The IT Band (Iliotibial Band) attaches the Gluteus Maximus (butt) muscle to the lower leg. These structures work together to help control the leg as it rotates over the foot during all weight bearing activities such as walking, running, squatting and lunging.  Rejuvenating and regenerating the IT Band (i.e., the tissues on the side of the thigh) with this self-myofascial release exercise can help recondition it and take stress of the foot, ankles, knees, hips and lower back.
