Train Muscles, Movement will Follow
You may have heard the phrase: "Train movements, not muscle." This concept is intended to encourage trainees to exercise in a "functional" manner; which places the training emphasis on capacity(mathematical model) instead of aesthetics(metaphorical model). This sounds like a valid concept, but it is a contradiction. The primary function of muscle is to move bones around joints; without muscle contractions, you have no movement. Muscle precedes Movement; there is no separation between movement and muscle, they interact within a continuous loop. The only reason to strength train is to create an adaptive response in the muscles. Whether the exercise is functional or not is dependent only on the exercises contribution to the end goal.
