The hip abductor muscles are the primary stabilizing muscles and serve to maintain your balance when you run. All other muscles, such as your quads, hamstrings, gluteus maximus, and calf muscles, are concerned with energy absorption when your foot strikes the ground and energy generation to propel you forward. The hip abductor muscles are the only muscles to maintain side-to-side balance. So keeping them good and strong is critical to prevent injuries and optimize your running mechanics.
