Know the basics...
Breathing:For your blood to circulate well and do its job of restoring and energizing your body, it requires oxygen. Deep, full inhalations are important in strength training and just as much attention needs to be paid to breathing as to the exercises themselves.
Centering:Learn to focus on your abdominal muscles, back, buttocks and hips. Building a strong core (or center) will flow out to the rest of your extremities and benefit you in every aspect of daily life.
Control:No sloppy, uncontrolled movements here. Your mind needs to be totally focused on your body and the exercises. Every exercise needs to be controlled to avoid injury and build strength. Slower is better!
Precision:Every exercise has a purpose and details are vital. It is better to do one precise move than to do many exercises the wrong way.
Fluidity:Every exercise is fluid. There is no isolation of muscles. Grace and balance replace quick, jerky moves. As a result, over time, uniformly developed muscles begin to cause good posture and natural grace in your sport and life.
