ABSTRACT:
The principle of the back exerciser is a pedal held in an initial position by elastic strips and a back brace and side handles in such relation that the person pressing on the side handles and bracing his back against the back brace, repeatedly pressing his heels on the pedal against the action of the elastic strips, exercises his back muscles. The structure is a skeleton frame with a pivoted pedal having its rear edge raised by elastic strips toward a back frame so that the elastic strips pull the back edge of the pedal upward and the front edge downward against a stop holding the pedal in a horizontal position. On the back frame at a suitable height is a padded back brace for the person to bear against when he presses the pedal down against the action of the elastic strips.
