Core strength is important in helping the body fight fatigue, prevent injury from overload and power explosiveness. A strong core preserves momentum as muscles transfer power from the upper body to the lower body (when running or sprinting, for instance) and the lower body to the upper body (like when punching). A strong core then helps develop physical power by minimizing the loss of force transfer across the body's muscles. Core Control will help you develop your core. As you feel yourself getting stronger you will find yourself becoming more physically capable.
