I cannot tell you how many injuries I have seen over the years from people adhering to bodybuilding and machine training principles instead of functional training principles.
Functional training is “reactive” teaching muscles to “fire” in a pattern, with primary “moving” muscles and secondary “stabilizing” muscles working in sequence to execute movement. This integration engages strong, stable “core” muscles aiding in balance. The result? Your body attains equilibrium between strength and flexibility, between agonist and antagonist muscles, increasing functionality while reducing risk of injury.
The bottom line: you can either have a bulky, unfunctional body that is injury prone or a lean, functional one that is resilient. It also never hurts that functional training workouts are shorter, more effective, and more interesting than all those monotonous curls, leg curls, bench presses, etc.
Principle #1
Integration vs. Isolation -
Strength training on machines works muscles in isolation-although it’s rare that your muscles would be required to work in isolation in any other situation. Functional training, on the other hand, removes the support provided by machines, requiring the body to work multiple muscle groups in integration, as the body is intended to move, resulting in more balanced muscle tone.
There are many reasons why functional exercises are important; here are some of the primary reasons:
Traditionally, when people exercise, they are working on “cosmetic fitness” – exercising to look good and working on surface muscles or those that we see. The problem with this is that it doesn’t help you in daily tasks. How often do you hear that someone hurt themselves reaching to the back seat of their car, turning quickly, or bending down quickly to pick up something? These are daily living tasks; therefore, it makes sense to train the muscles doing similar movements. You aren’t lying down most of the day doing crunches, yet your abdominal muscles are constantly working to stabilize your spine. So why not train them in a way that makes sense (i.e. standing, sitting, twisting)? That’s what core and functional training are about, and there are several methods you can use.
