Here is another exercise machine that lets you work on your thighs and butt. The Bun and Thigh Rocker with Powerflex Bands is pretty simple to use. Simply take a seat, plant your feet on either side, and lower your body onto the seat. Simply press upward so the backrest slides up to the top of the machine.
The machine prevents injuries and lets you add resistance bands to increase difficulty as your body gets stronger.
