HOW: Start by lying on your back with a band looped around the bottom of your foot. While holding the band, bring both arms above your head and anchor the band to the ground. Keep your toes pointed up as you let the band pull your leg up with your leg straight. When your leg is as high as you can comfortably go, push into the band and drive your leg back down into the starting position.
FEEL: You should feel your hamstring and glute working.
COMPENSATION: Keep your knee straight, don’t bend it. Control the band going up and down, don’t let the band control you. Don’t let your body or other leg twist or rotate.
