HOW: Begin by lying on your back and bringing one knee up towards your chest. Grab onto the back of your thigh with both hands and relax your lower leg. From here, point your ankle in and down as you kick your leg straight up slow and controlled. Stay in a comfortable range of motion for each rep.
FEEL: You should feel a stretch in your lower leg and even the back of your thigh.
COMPENSATION: Keep the toes and ankle pointed down and inward the entire time.
