  1. The ornamental design for a back strengthener, as shown and described.
Description

This application claims the benefit of U.S. utility patent application Ser. No. 12/080,545, filed Apr. 3, 2008 by the present inventor.

FIG. 1 is a front and top perspective view showing my new design;

FIG. 2 is a front and bottom perspective view thereof;

FIG. 3 is a front elevational view thereof; and,

FIG. 4 is a top plan view and the bottom plan view being a mirror image thereof.

My back strengthening device is characterized by an elevated convex shaped middle section with two adjacent elongated flat surfaced convoluted structures, and one smaller pole centrally positioned covered at each end with shorter but slightly larger convoluted pieces.

The broken lines shown in the drawings represent unclaimed portions of the Device and form no part of the claimed design.
