Lil' gym

A person in a white shirt and brown pants lies on their back on a green mat, while another person in a patterned shirt and brown pants stands over them, adjusting a black strap around their waist. The standing person pulls the strap tight, then releases it, causing the strap to snap back and the person on the ground to be lifted slightly. The scene takes place on a green mat with a blue mat visible in the background.
