HOW: Loop a strong resistance band around a pull up bar or something tall and sturdy. Pull the band down and lay on your back underneath the band. Loop it around the ankle of the leg you want to work. Start with your leg curled and slowly let the band pull the leg straight as you resist the tension of the band. Once it is straight, use the other leg and place it on top to curl the leg back down to repeat the process. FEEL: You should feel your hamstring muscles working. COMPENSATION: Control the band as you straighten your leg, don’t let the band abruptly pull your leg up. Use the free leg to help curl it back down. Exercise Library
