KEY CONCEPT
Compromised joint movement alters neuromuscular control and function, prompting additional postural misalignments and faulty loading at the joints that inevitably increases overload and the likelihood for further injury and pain (Figure 9-9). It is therefore imperative that trainers work to restore and maintain normal joint alignment, joint movement, muscle balance, and muscle function, all of which are critical for optimal health and longevity. Effective programming and attention to exercise technique will help the trainer achieve this goal.
THE OBJECTIVE OF THIS FIRST PHASE OF FUNCTIONAL MOVEMENT AND resistance training is to reestablish appropriate levels of stability and mobility within the body. This process begins by targeting an important proximal region of the body,
