The center of it all.

The torso or core is what connects all the moving body parts around it. The spine is the conduit which transfers power from your lower body to your upper body. Core postural muscles can be used to free your swinging action and allow you to impart more force in your ball strike. Improve your core stabilization now for better form on the courts!  -Tracy
