Complete Muscular Development
You need an un-wavering mind set to work out your entire body; and the entire muscle. Balance within a muscle or a muscle group is a pre-requisite to overall muscular balance. Complete development creates full muscle bellies and allows for a fully proportional body of muscles. You achieve complete muscle development through variety and focus.
Variety – Constantly vary your workouts and what you use. Your body will adapt to the same planes of motion and resistance. Use cables, dumbbells, keep switching the grip, hand position, etc. Every muscle we have has fibers that run on different planes. If you take the chest, it starts on the sternum and attaches below the shoulder; so you have fibers that run across, down, and that sweep around. If you continually work at different planes, you work the entire muscle.
Muscle Function – Most people go through the motions of lifting. By focusing on muscle function, you are effectively isolating and targeting the muscle. Muscle function is the understanding of what a muscle or group of muscles do when contracted (line of pull). This focus helps work the entire muscle and forces you to lift the weight, not throw.
