Description

This application claims priority to and the benefit of U.S. Provisional Application No. 61/052,038, filed on May 9, 2008, which is incorporated in its entirety in this document by reference.

FIELD OF THE INVENTION

This invention relates generally to the field of exercise equipment. In particular, the invention relates to a fitness paddle that allows a user to simulate the action of paddling a canoe or kayak, thereby providing both aerobic and anaerobic exercise.

BACKGROUND OF THE INVENTION

Watercraft paddling sports involve a person propelling a watercraft through a body of water such as a river or lake with a paddle. Two common watercraft paddling sports are canoeing and kayaking. Canoes are small, narrow boats that are usually pointed at both ends and open on top. Most canoeists use a paddle having a single paddling blade on one end of a shaft, and a T-shaped handle on the other end. In order to paddle a canoe, a canoeist sitting or kneeling in a canoe typically places one hand on the shaft of the paddle, and the other hand on the T-shaped handle. The blade is then dipped into the water on the side of the canoe and pulled backward, causing the canoe to move forward through the water.

Kayaks are also small narrow boats that are usually pointed on both ends, and are usually closed on top. Kayaks are typically propelled by a double-bladed paddle, i.e. a shaft having a blade on both ends. In order to propel a kayak, a kayakist typically spaces his or her hands along the shaft, and alternatively dips each blade into the water on either side of the kayak.

SUMMARY OF THE INVENTION

According to various aspects, the present invention is a fitness paddle exercise device for simulating the action of paddling a canoe or a kayak. In one aspect, the device can comprise an elongate rod having a longitudinal axis, a proximal end and an opposed distal end. In another aspect, the device can further comprise a first assembly comprising a first member and a second member attached to the distal end of the rod. In still another aspect, the second member can have at least two degrees of freedom relative to the longitudinal axis of the rod. In one embodiment, the first assembly can comprise a first member configured to be rotatably attached to the elongate rod, and a second member rotatably attached to the first member. In this aspect, the second member can be releasably attached to a resistance source, such as, for example and without limitation, a weight stack or an elastic cord to provide a user both aerobic and anaerobic exercise.

In another embodiment, the first assembly can comprise a first ball and socket interconnection comprising a first ball member and a first socket member, wherein the first ball member has at least three degrees of freedom relative to the longitudinal axis of the rod. In this aspect, the first socket member can be attached to the distal end of the elongate rod, and the first socket member can be adapted to receive the first ball member such that when the first ball member is received in the first socket member it is capable of pivotal and rotational movement within the socket. A first ring can be fixedly attached to the first ball member and a resistance source can be releasably attached to the first ring.

In another aspect, the device can further comprise a second assembly. In one aspect, the second assembly can be substantially the same as the first assembly. The second assembly can, in another aspect, be attached to the proximal end of the elongate rod. In still another aspect, a second member of the second assembly can have at least two degrees of freedom relative to the longitudinal axis of the rod. In this aspect, the second member of the second assembly can be releasably attached to a resistance source, such as, for example and without limitation, a weight stack.

In still another aspect, the device can further comprise a handle configured to be attached to the proximal end of the elongate rod. The handle can be mounted such that a longitudinal axis of the handle can be substantially perpendicular to the longitudinal axis of the elongate rod so that user can simulate canoe paddling.

In yet another aspect, the device can further comprise a first connector having a proximal end and a distal end. The proximal end of the first connector can be selectively and releasably attached to the first assembly, and the distal end of the first connector can be selectively and releasably attached to a resistance source.

A fitness paddle exercise device is provided, according to various aspects of the present invention. In one embodiment, as shown in FIG. 1A, the exercise device 10 can comprise an elongate rod 20 and a first assembly 40 configured to be fixedly attached to the elongate rod. In one aspect, the first assembly comprises a first member 42 and a second member 44. In this aspect, the second member can be releasably attached to a resistance source, such as, for example and without limitation, a weight stack. In one exemplary embodiment, illustrated in FIG. 1B, the exercise device can further comprise a second assembly 80 fixedly attached to the elongate rod. In another aspect, the second assembly can be substantially the same as the first assembly.

One embodiment of the elongate rod 20 is illustrated in FIG. 2A. In one exemplary embodiment, the elongate rod 20 can be substantially cylindrical and have a proximal end 22, an opposed distal end 24, and a longitudinal axis. In one aspect, the elongate rod can extend for a predetermined distance. In another aspect, the distal end of the elongate rod can define a first orifice 26 having a longitudinal axis that is substantially co-axially aligned with the longitudinal axis of the elongate rod and that can be configured for receiving at least a portion of the first assembly 40 therein. In still another aspect, the proximal end of the elongate rod 20 can define a second orifice 28 having a longitudinal axis that is substantially co-axially aligned with the longitudinal axis of the elongate rod and that can be configured for receiving at least a portion of the second assembly 80 therein.

In one aspect, the elongate rod 20 can comprise at least one shaft end member 29. In another aspect, the elongate rod can comprise two shaft end members. In still another aspect, the at least one shaft end member can have a proximal end configured to be securedly attached to the first orifice 26 or the second orifice 28 of the elongate rod. In one aspect, the at least one shaft end member 29 can be fixedly attached to an end of the elongate rod by known methods, including, for example and without limitation, welding the pieces together, adhering the pieces with an epoxy or other adhesive, threading the pieces together, pressure fitting the pieces together, screwing or bolting the pieces together, or other conventional attachment methods.

In another aspect, the at least one shaft end member can have a distal end that is configured to interact with the first assembly 40 or the second assembly 80, described more fully below. In yet another aspect, at least a portion of the at least one shaft member can have a cross-sectional diameter substantially equal to the cross-sectional diameter of the elongate rod 20. In another aspect, however, the distal end of the at least one shaft member can have a cross-sectional diameter less than the cross-sectional diameter of the elongate rod. In still another aspect, the cross-sectional area of the at least one shaft end member 29 can be tapered toward the distal end of the at least one shaft end member.

Generally, for clarity, the first assembly 40 and the second assembly 80 are described herein as being attached to the distal end 24 or the proximal end 22 of the elongate rod. It is of course contemplated, as one skilled in the art will appreciate, that in different embodiments of the device 10, the first assembly and the second assembly, if present, can also be attached to the at least one shaft end member 29 on the distal end and/or the proximal end of the elongate rod 20. Additionally, it is of course contemplated that in different embodiments of the device the first assembly and the second assembly can also be attached to the elongate rod at various other locations along the length of the elongate rod. For example, in one aspect, the first assembly and/or the second assembly can be offset from the ends of the rod a distance, which offset optionally can be selected by the operator.

In one aspect, the elongate rod can be a single continuous rod. In another aspect, as illustrated in FIG. 8, the elongate rod 20 can be a telescopic rod formed from a plurality of segments 30 that can be nested inside of a center segment 32 of the plurality of segments. The center segment 32 can have a distal end 34 and a proximal end 36, and nested segments can be extendable from both the distal and proximal ends of the center segment. In one aspect, upon extension of the segments, the segments 30 can be held in place by spring-loaded retaining pins 38 that are configured to be complementarily received in bores 39 formed in mating segments. To collapse the telescopic rod, a user can push the spring-loaded retaining pins inwardly towards the center of the rod, thereby allowing the extended segments to be inserted into the center segment. To extend the telescopic rod, a user can simply pull the nested segments 30 out of the center segment 32 until the spring-loaded retaining pins snap into place in the bores of the mating segments.

In another aspect, the elongate rod 20 can be formed from a plurality of segments 30 that are selectively detachable from each other. In this aspect, the segments can be attached to each other by, for example and without limitation, threads on one end of a segment and complementary mating threads on the end of a mating segment. In this manner, the elongate rod can be broken down into a plurality of pieces by unthreading the segments. The elongate rod can be assembled by threading the segments together, so that an elongate rod, as described above, is formed. In one example, and as illustrated in FIG. 11, the elongate rod 20 can be formed from two mating segments, such that the two segments are of substantially equal length. In another aspect, the segments can be attached to each other by, for example and without limitation, bolts, screws, pins, and the like.

One embodiment of the first assembly 40 is illustrated in FIG. 3C. In one aspect, the first assembly can be comprised of the first member 42 and the second member 44. In another aspect, and as illustrated in FIG. 3A, the first member can have a proximal end 48, a distal end 46, and a longitudinal axis. In one aspect, the proximal end of the first member can be configured to be inserted into the orifice 26 defined in the distal end 24 of the elongate rod 20 such that the first member 42 can be fixedly attached to the elongate rod. In another aspect, the first member can define at least one bore 52 having a fixed diameter configured or otherwise sized or shaped for rotatable attachment with the second member 44. In still another aspect, the at least one bore can comprise a plurality of bores 52. In another aspect, between the proximal end 46 and the distal end 48 of the first member, there can be a bearing 50 that allows the distal end of the first member to rotate freely with respect to the proximal end of the first member, while the proximal end of the first member 42 does not rotate and is held in fixed contact with the elongate rod.

In another aspect, and as shown in FIG. 3B, the second member 44 of the first assembly can be a rod 58 formed such that it is substantially D-shaped, though it is contemplated that the second member could be other shapes, such as, for example and without limitation, substantially circular, substantially oval, substantially square or substantially rectangular. In one aspect, the rod can have a diameter that is slightly smaller than the diameter of the plurality of bores 52 defined therein the first member 42. In another aspect, the second member can have a first end 54 and a second end 56 that do not meet, and thus do not form a continuous ring. In another aspect, the first end and the second of the second member can be positioned to form a substantially continuous ring. The two ends of the second member can be substantially co-axially aligned, and can be separated by a distance that is less than the thickness of the proximal end 46 of the first member.

In one exemplary aspect, with reference to FIGS. 3C and 1A, this embodiment of the first assembly 40 can be assembled and attached to the distal end 24 of the elongate rod by inserting the proximal end 48 of the first member 42 into the orifice 26 defined in the distal end of the elongate rod 20, such that the longitudinal axis of the first member is substantially co-axially aligned with the longitudinal axis of the elongate rod. The first member can then be fixedly attached to the elongate rod by known conventional attachment methods, including, for example and without limitation, welding the pieces together, adhering the pieces with an epoxy or other adhesive, threading the pieces together, pressure fitting the pieces together, screwing or bolting the pieces together, or other attachment methods. A first end 54 of the second member 44 can be inserted into one of the plurality of bores 52 defined therein the first member 42, and a second end 56 of the second member can be inserted into another bore of the plurality of bores 52 defined therein the first member. In this aspect, upon insertion of the second member 44 into the first member 42, the second member can rotate around an axis substantially perpendicular to the longitudinal axis of the first member, and thus, the longitudinal axis of the elongate rod, and in a plane that bisects the longitudinal axis of the rod. Thus, when assembled as described herein, in this embodiment, the first member can rotate with respect to the longitudinal axis of the elongate rod, and the second member can rotate relative to both the longitudinal axis of the elongate rod 20 and in a plane bisecting the longitudinal axis of the elongate rod.

Another embodiment of the first assembly 40 is illustrated in FIG. 4C. In this embodiment, the first assembly can be comprised of the first member 42 and the second member 44. In another aspect, the first member 42 can comprise a fastening member 60 and a rotating member 62. In one aspect, the fastening member, such as a screw, bolt, or the like can have a neck having a neck diameter and can be configured to fixedly attach the first assembly to the distal end 24 of the elongate rod 20. In one exemplary aspect, the fastening member can fixedly attach the first assembly 40 to the elongate rod by matingly engaging threads defined in the orifice 26 defined in the distal end of the elongate rod. In this aspect, the fastening member 60 can be configured such that, when assembled as described herein, a portion of the fastening member can extend through a first bore 64 of the rotating member 62 and matingly engage the threads in the distal end of the elongate rod. In another aspect, the fastening member 60 can fixedly attach the first assembly to the elongate rod by forming a pressure fit between the fastening member and the orifice of the elongate rod 20. In still another aspect, the fastening member can fixedly attach the first assembly 40 to the elongate rod by other known attachment methods.

As illustrated in FIG. 4A, the rotating member 62 of the first member 42, in one aspect, can have a longitudinal axis extending from an upper surface 68 of the rotating member to a lower surface 69. In another aspect, the rotating member can define a substantially circular first bore 64 that extends from an upper opening 61 defined in the upper surface of the rotating member to a lower opening 63 defined in the lower surface, the first bore being substantially parallel to the longitudinal axis of the rotating member. In another aspect, the first bore of the rotating member 62 can have a diameter slightly larger than the diameter of the neck of the fastening member 60. In another aspect, the rotating member can define a second bore 66 having a longitudinal axis substantially transverse to the longitudinal axis of the rotating member.

The second member 44 of this embodiment of the first assembly 40 is illustrated in FIG. 4B. In one aspect, the second member can have a proximal end 70 and a distal end 72. In one aspect, a slot 74 can be formed in the proximal end of the second member, which, in one example, can bifurcate the proximal end of the second member into two portions separated by a distance. In another aspect, at least a portion of the bifurcated proximal end 70 of the second member 44 can be configured to receive a portion of the rotating member 62. Still referring to FIG. 4B, the second member can define a substantially circular rotation bore 76 having a predetermined radius and a longitudinal axis. In one aspect, the rotation bore can extend from a front surface 77 of the second member 44 through the slot 74 and to a rear surface 78 of the second member. As shown in FIG. 4C, the rotation bore can be configured to receive a rotation element 73, such as for example and without limitation, a pin, screw, bolt, or the like, about which the second member can rotate. In still another aspect, the second member 44 can define a substantially circular connection bore 79 configured for receiving a first connector or a second connector, described more fully below. In another aspect, a longitudinal axis of the connection bore can be substantially parallel to the longitudinal axis of the rotation bore 76.

In one exemplary aspect, with reference to FIG. 4C, this embodiment of the first assembly 40 can be assembled and attached to the distal end 26 of the elongate rod 20 by inserting the neck of the fastening member 60 therethrough the first bore 64 of the rotating member 62 in a direction from the upper surface 68 of the rotating member to the lower surface 69, until at least a portion of the fastening member protrudes from the lower opening 63 of the rotating member. At least a portion of the neck of the fastening member that protrudes from the lower opening can be fixedly attached to the orifice 26 defined therein the distal end of the elongate rod. In one aspect, the fastening member 60 can fixedly attach the rotating member 62 to the elongate rod while still allowing the rotating member to rotate about the longitudinal axis of the rod. In another aspect, a portion of the rotating member can be inserted into the slot 74 of the second member 44 such that the second bore 66 of the first member is co-axially aligned with the rotation bore 76 of the second member. In another aspect, the rotation element 73 can be inserted therethrough the co-axially aligned bores to create a hinge about which the second member can rotate. In still another aspect, the second member 44 can rotate in a plane bisecting the longitudinal axis of the first bore 64 of the rotating member of the first member 42. Thus, when assembled as described herein, in this embodiment, the first member can rotate with respect to the longitudinal axis of the elongate rod, and the second member can rotate relative to both the longitudinal axis of the elongate rod 20 and in a plane bisecting the longitudinal axis of the elongate rod.

FIG. 5A illustrates another embodiment of the first assembly 40. In this embodiment, the first assembly can be comprised of a first ball and socket interconnection member 140 and a second member 142. The first ball and socket interconnection member can be comprised of a first ball member 144 and a first socket member 146. In one aspect, the first socket member can be adapted to receive the first ball member and have a mounting arm 152 protruding from the socket member configured to be inserted into the orifice 26 defined in the distal end of the elongate rod 20. In this aspect, when the first ball member is received within the first socket member, the first ball member can have at least three degrees of freedom, i.e. it can be capable of both pivotal and rotational movement within the socket. In another aspect, the first ball member 144 can have a first spacing arm 148 protruding from the ball. The first spacing arm can have a distal end 150 extending a predetermined distance from the ball. In one aspect, as illustrated in FIG. 5A the first spacing arm can be substantially straight. In another aspect, as illustrated in FIG. 5B, the first spacing arm 148 can have at least one bend in it.

In this embodiment, the second member 142 can be a rod formed such that it is substantially D-shaped, though it is contemplated that the second member could be other shapes, such as, for example and without limitation, substantially circular, substantially oval, substantially square or substantially rectangular. In one aspect, the second member 142 can have two ends that are adjacent to each other, forming a continuous ring, and the second member can be attached to the first spacing arm 148 by conventional means, such as, for example and without limitation, welding or otherwise adhering.

This embodiment of the first assembly 40 can be assembled and attached to the distal end 24 of the elongate rod 20 by inserting the mounting arm 152 of the first socket member 146 into the orifice 26 defined in the distal end of the elongate rod. The first socket member can be fixedly attached to the elongate rod by known attachment methods, as discussed above. The first socket member can receive the first ball member 144 in the socket of the first socket member, and the second member 142 can be attached to the first spacing arm 148 by known methods including, for example and without limitation, welding or otherwise adhering them together. When assembled as described herein, in this embodiment, the first ball member can have at least three degrees of freedom relative to the longitudinal axis of the elongate rod 20, i.e. it can be capable of both pivotal and rotational movement within the socket.

FIG. 6 illustrates another embodiment of the first assembly 40. In this embodiment, the first assembly can comprise a rotating neck 160, a fastener 162, and a second member 164. In one aspect, the rotating neck can be substantially circular having an inner diameter, an outer diameter, and a longitudinal axis. The fastener can be, without limitation, a bolt, screw, pin or the like. The second member 164 can be a rod formed into a substantially circular shape, and having a first end 166 attached to the rotating neck and a second end 168 attached to an opposed side of the rotating neck. Although a substantially circular second member 164 is illustrated, other shapes, including, for example and without limitation, substantially oval, substantially square or substantially rectangular are contemplated. In this aspect, the second member can be attached to the rotating neck 160 by conventional means, such as, for example and with limitation, welding or otherwise adhering them together.

This embodiment of the first assembly 40 can be assembled and attached to the distal end 24 of the elongate rod 20 by placing the rotating neck 160 over the orifice 26 defined in the distal end of the elongate rod. In one aspect, a portion of the fastener 162 can be inserted through the inner diameter of the rotating neck into the orifice 26 defined therein the distal end of the elongate rod to fixedly attach the first assembly to the elongate rod. The fastener can be fixedly attached to the elongate rod 20 by known attachment methods, including for example and without limitation, welding, adhering, threading and other conventional attachment methods.

In another aspect, the exercise device 10 can further comprise a second assembly 80 configured to be fixedly attached to the proximal end 22 of the elongate rod 20. In this aspect, with both the first assembly and the second assembly attached to respective ends of the elongate rod 20, a user of the device 10 can be provided resistance from both ends of the rod, as would occur in paddling a kayak.

In one aspect, the second assembly 80 can be formed similarly to any of the embodiments of the first assembly 40, as previously described. In another aspect, the exercise device 10 can be further assembled by fixedly attaching the second assembly 80 to the proximal end 22 of the elongate rod. The second assembly can be attached to the elongate rod 20 in any of the manners described above with reference to attaching the first assembly 40 to the elongate rod.

In other aspects, it is contemplated that the first assembly 40 can be selectively placed, in addition to the distal end 24 of the elongate rod, at any one of a plurality of locations along the length of the elongate rod. In one exemplary aspect, the elongate rod can define a plurality of mounting bores spaced along the length of the elongate rod, such that the first assembly can be selectively bolted to the elongate rod at a desired one of the plurality of mounting bores. In another aspect, the first assembly can further comprise a clamping element, such that the first assembly can be selectively clamped to the elongate rod at any location the user selects. In still other aspects, it is contemplated that the first assembly 40 can be selectively attached to the elongate rod at any location by other conventional attachment methods. Thus, the first assembly can be offset along the longitudinal axis of the elongate rod 20 a predetermined distance from the distal end 24 of the rod.

Similarly, in various other aspects, it is contemplated that the second assembly 80 can be placed, in addition to the proximal end 22 of the elongate rod, at any one of a plurality of locations along the length of the elongate rod. In one exemplary aspect, the elongate rod 20 can define a plurality of mounting bores spaced along the length of the elongate rod, such that the second assembly can be selectively bolted to the elongate rod at a desired one of the plurality of mounting bores. In another aspect, the second assembly can further comprise a clamping element, such that the second assembly can be selectively clamped to the elongate rod at any location the user selects. In still other aspects, it is contemplated that the second assembly 40 can be selectively attached to the elongate rod at any location by other conventional attachment methods. Thus, the second assembly can be offset along the longitudinal axis of the elongate rod 20 a predetermined distance from the proximal end of the rod.

In still another aspect, the device 10 can further comprise at least one cushioning grip 180, illustrated in FIG. 9. The at least one cushioning grip can be formed from a soft cushioning material, for example and without limitation, foam. The at least one cushioning grip can have a substantially tubular shape configured to fit over the elongate rod 20. In one aspect, the at least one cushioning grip can have an inner diameter that is substantially the same as the diameter of the elongate rod, and the at least one cushioning grip 180 can be adhered to the elongate rod using conventional adhesives. In another aspect, the at least one cushioning grip can be formed with a slit in a longitudinal direction through the thickness of one side of the at least one cushioning grip so that the at least one cushioning grip 180 can easily be placed over the elongate rod, at any location along the length of the elongate rod.

In yet another aspect, the exercise device 10 can further comprise a handle 200, as illustrated in FIG. 7, configured for selective, releasable attachment to the proximal end 22 of the elongate rod 20. In one aspect, the handle can have a longitudinal axis that, when attached to the elongate rod, is substantially perpendicular to the longitudinal axis of the elongate rod. In another aspect, the handle can be configured to simulate the shape and feel of the end of a canoe paddle, and can be attached to the elongate rod by, for example and without limitation, a bolt, screw, or other similar restraining device. In yet another aspect, the handle can be threaded, and the proximal end 22 of the elongate rod can be complementarily threaded, such that the handle 200 can be screwed onto the proximal end 22 of the elongate rod 20. In another aspect, for example, if a user desires resistance from only one end of the device, as in paddling a canoe, instead of attaching the second assembly to the proximal end of the elongate rod, the handle 200 can be detachably secured to the proximal end of the elongate rod. Additionally, a user can choose to alternate between selectively attaching the second assembly 80 and the handle 200 to the proximal end of the elongate rod, so that resistance can be alternatively, selectively provided from both ends of the device and then only one end.

In another aspect, as illustrated in FIG. 10, the exercise device 10 can further comprise a first connector 210 having a proximal end and a distal end. In various aspects, the first connector can be an elastic cord, rope, wire or the like. In one aspect, the proximal end of the first connector can be selectively, releasably attached to the first assembly 40 of the exercise device. In another aspect, the distal end of the first connector can be selectively, releasably attached to a resistance source 214, such as, for example and without limitation, a weight stack or, if the first connector 210 is an elastic cord, a stationary object, such as, for example and without limitation, a door knob, a doorjamb, a table leg, and the like. In one aspect, then, when assembled as described herein, the first connector can be movable about at least three degrees of freedom relative to the longitudinal axis of the elongate rod 20, i.e., the first member 42 of the first assembly 40 can rotate about the longitudinal axis of the elongate rod; the second member 44 of the first assembly can rotate about a plane bisecting the longitudinal axis of the elongate rod; and the first connector 210 can rotate within the connection bore 79 of the second member 44.

In another aspect, the device can further comprise a second connector 212 having a proximal end and a distal end. In various aspects, the second connector can be an elastic cord, rope, wire or the like. In one aspect, the proximal end of the second connector can be selectively, releasably attached to the second assembly 80. In another aspect, the distal end of the second connector can be selectively, releasably attached to a resistance source, as described above. Thus, in one aspect, when assembled as described herein, the second connector can be movable about at least three degrees of freedom relative to the longitudinal axis of the elongate rod 20, i.e., the first member 42 of the second assembly 80 can rotate about the longitudinal axis of the elongate rod; the second member 44 of the second assembly can rotate about a plane bisecting the longitudinal axis of the elongate rod; and the second connector 212 can rotate within the connection bore 79 of the second member 44. Optionally, in other aspects, the second connector 212 can be attached to the same resistance source that the first connector 210 is attached to, or alternatively, the second connector can be attached to a different resistance source than the first connector.

In one aspect, the components of the exercise device can be formed from steel, such as, for example, stainless steel. It is contemplated, as can be appreciated by one skilled in the art, that the components of the exercise device 10 can be formed from other metals, such as, for example and without limitation, aluminum, titanium and the like. It is further contemplated that the components of the exercise device can be formed from polymeric materials, including fiber-reinforced polymers, such as, for example and without limitation, fiberglass. It is further still contemplated that the elongate rod 20 can be formed from wood. It is also contemplated that the exercise device can be formed from a combination of wooden, metallic components and polymeric components.

In order to use the exercise device 10, a user can attach the exercise device to a resistance source 214, such as, for example and without limitation, a weight stack. In one aspect, the user can releasably attach a cable from a weight stack, as are commonly known in the art, to the first assembly 40. In another aspect, it is contemplated that the user can position the first assembly at a desired location along the length of the elongate rod. The user can, if desired, selectively, releasably attach the handle 200 to the proximal end 22 of the elongate rod. The user can then sit, kneel or stand a distance away from the weight stack and move the device to cause the weight stack to rise repetitively, thereby providing both aerobic and anaerobic exercise. In this aspect, the user can move the device 10 in a motion similar to that used in paddling a canoe. However, the user can move the device through various other directions in the frontal, sagittal and horizontal planes.

Optionally, in another aspect, the user can releasably attach the proximal end of the first connector 210 to the first assembly 40, and the distal end of the connector to a resistance source 214. If the first connector is an elastic connector, the distal end of the connector can be releasably attached to a stationary resistance source, such as, for example and without limitation, the frame of a weight stack, a door knob, a doorjamb, a table leg, and the like. If the first connector 210 is a non-elastic connector, such as, for example and without limitation, a rope or wire, the distal end of the first connector can be releasably attached to a mobile resistance source, such as, for example and without limitation, a weight stack. The user can then sit, kneel or stand a distance away from the resistance source and move the device repetitively, thereby providing both aerobic and anaerobic exercise. In this aspect, the user can move the device in a motion similar to that used in paddling a canoe. Again, however, the user can move the device through various other directions in the frontal, sagittal and horizontal planes.

In various other aspects, in addition to having a first resistance source attached to the first assembly 40, as described above, the user can attach a second resistance source to the second assembly 80. Additionally, in another aspect, it is contemplated that the user can position the second assembly at a desired location along the length of the elongate rod. In one aspect, the second resistance source can be the same resistance source as the first resistance source. In another aspect, the user can releasably attach a cable from a weight stack, to the second assembly of the exercise device 10. The user can then sit, kneel or stand a distance away from the weight stack and move the device to cause the weight stack to rise repetitively, thereby providing both aerobic and anaerobic exercise. In this aspect, the user can move the device 10 in a motion similar to that used in paddling a kayak. However, the user can move the device through various other directions in the frontal, sagittal and horizontal planes.

In yet another aspect, the user can releasably attach the proximal end of the second connector 212 to the second assembly 80, and the distal end of the connector to a second resistance source. If the second connector is an elastic connector, the distal end of the connector can be releasably attached to a stationary resistance source, such as, for example and without limitation, the frame of a weight stack, a door knob, a door jamb, a table leg, and the like. If the second connector is a non-elastic connector, such as, for example and without limitation, a rope or wire, the distal end of the connector can be releasably attached to a mobile resistance source, such as, for example and without limitation, a weight stack. The user can then sit, kneel or stand a distance away from the resistance source and move the device repetitively, thereby providing both aerobic and anaerobic exercise. In this aspect, the user can move the device 10 in a motion similar to that used in paddling a kayak. Again, however, the user can move the device through various other directions in the frontal, sagittal and horizontal planes.
