HOW: Get set-up standing with a band around and above the knee with the band anchored in front of you. To perform the exercise, put tension on the band so that it wants to pull your knee forward, balance on the leg with the band, then perform a single leg squat and let your knee bend forward in line with your foot while keeping your chest up. Then return to starting position by squeezing your quad and pushing your knee back until it is fully straight.
FEEL: You will feel your quads working with this exercise and your glutes and calves. You may also feel a stretch behind your knee in the calf and hamstring region when your knee is straight
COMPENSATION: Focus on staying tall with your chest up as you perform this exercise. Do not lean side to side, lose your balance, or have poor knee alignment. Make sure your hip is pushed forward with your knee straight at the top of the movement.
