Instructions
Loop a light resistance band around at the base of a thin stable structure like a fence railing or even a small tree. Lie on your stomach with the powerband looped around one ankle. With the other leg straight, curl the leg with the powerband attached up to a 90 degree angle, then release it back down. Repeat for the desired number of reps and then repeat on the other leg.
Tips
Move further away from the structure that the powerband is attached to, to create more resistance, or set yourself closer for less resistance.
