Stability training improves neuromuscular efficiencies, giving athletes greater motor control within a muscle and between muscle groups. Even with lighter loads all muscle fibers are completely engaged.
Unstable weight gives athletes immediate feedback when technique is correct. Incorrect form is magnified making it easier to correct.
Stabilizing muscles tend to be underdeveloped in athletes, often leading to injury. Recruiting these stabilizing muscles helps to recover from as well as prevent common injuries.
