A way to strengthen your right gluteus medius (in this case). You should stand on the side you are trying to strengthen with nice alignmet in your upper body (no leaning and upright posture). Your knee can be slightly bent but no further bending or straightening should occur during the exercise. All of the up and down movement should come from your pelvis raising and lowering below and just slightly above horizontal. People who are weak tend to use their left lower back to do this exercise but it should be done using the right gluteus medius muscle. Thus, you should feel fatigue in the right hip if you are doing it correctly. Remember, no leaning your trunk/shoulders !
