Relaxation, both mental and physical, is something repeatedly referred to in The Tao of Jeet Kune Do, as it should be with all sports and martial arts. In any movement, we have something called “force-couple relationships” occurring. This means that muscles—agonists, synergists, stabilizers, neutralizers, and antagonists—are working together to create the most efficient movement around a joint.17 To maximize efficiency, we want to minimize extraneous motion and unnecessary tension.
I’ve just mentioned muscles called agonists and antagonists. Agonists are prime movers that create joint motion. For instance, when we throw out a straight lead, we are performing a pushing motion. The triceps act as prime movers. Antagonists are muscles that act in direct opposition to the prime movers.18 As we throw out a lead punch, the biceps are antagonists, because they are involved mainly in pulling motions. Therefore, they act in opposition to the triceps. As we shoot out a straight, then, we want to activate the triceps while relaxing the biceps.
