Instructions
First, attach one end of the resistance band comfortably around your ankle
Lie prone on an exercise mat, with your arms folded together cushioning your head while holding the other end of the resistance band on the same side as the attached ankle
When ready, inhale and slowly bend at the knee to bring your heel up towards your glutes, while keeping your other leg fully grounded
Once your knee reaches a 90-degree bend, slowly exhale and control it smoothly back down to the starting position
