Hip flexion performed with the band while standing strengthens the hip flexors. These muscles help move your thigh toward your abdominals. It’s important to develop both extension and flexion at the hip joint to prevent injuries and imbalances. Keep your knee locked and our toes pointed up toward your shins as you raise your leg. This will keep the tension on the hip joint and not on the thigh. This exercise can be performed at home or at the gym.
