The hip hike exercise strengthens your hit abductors which are essential to pelvic stability. Strengthen your hip abductors in order to prevent common knee pains. Push the pelvis sideways against the band until the left side of the pelvis is higher than the right. The hip abductors, among them the gluteus medius, pull the pelvis and create lateral flexion. Weak gluteus medius muscles are a common reason for knee valgus, ITB syndrome, hip and lower back problems. Keep your pelvis stable.
