US Patent 11266866 Portable exercise device

The portable exercise device is a physical training device. The portable exercise device is an elastic structure that generates a counterforce used to exercise muscles. The portable exercise device comprises a plurality of resistance bands, a plurality of supporting bars, and a plurality of carabiners. The plurality of carabiners attaches the plurality of resistance bands to the plurality of supporting bars. Each of the plurality of supporting bars is a rigid structure to which the plurality of resistance bands anchors. The plurality of supporting bars are manipulated to apply deformation forces to the plurality of resistance bands during the use of the portable exercise device. The plurality of resistance bands generates the counterforce used to exercise muscles as each of the plurality of resistance bands returns to the relaxed shape.
