## Abstract

The system of the present invention includes elastic bands that are affixed and inserted within elastic band insertion slots that are disposed on a u-shaped frame and a rectangular-shaped frame. The squatting motion the user performs on the present invention activates the expansion and retraction of the elastic bands, which exerts resisting force upon the user, simulating weights.
