I call these the magic muscles - Glute Medius, Transverse Abdominis, Internal Oblique – If they can do everything people think they do then they must be magic! Stability is a moving target; no one muscle can be responsible for stability. It is these muscles working in synergy with other muscles that produce efficient flowing movement that reduces and produces force effectively. As far as compensation, it does occur. There is normal and abnormal compensation. Athletes are great compensators; they know their bodies and how to efficiently accommodate. Abnormal compensation usually results from some sort of a traumatic event that forces the athlete is a position or a series of movements that they cannot handle.
