Functional Movements:

There are movements that mimic motor recruitment patterns that are found in everyday life. Others are somewhat unique to the gym. Squatting is standing from a seated position; deadlifting is picking any object off the ground.They are both functional movements. Leg extension and leg curl both have no equivalent in nature and are in turn nonfunctional movements. The bulk of isolation movements are non-functional movements. By contrast the compound or multi-joint movements are functional. Natural movement typically involves the movement of multiple joints for every activity.

The importance of functional movements is primarily two-fold. First of all the functional movements are mechanically sound and therefore safe, and secondly they are the movements that elicit a high neuroendocrine response. The superiority of training with functional movements is clearly apparent with any athlete within weeks of their incorporation.

The soundness and efficacy of functional movement is so profound that exercising without them is by comparison a colossal waste of time. For this reason functional movement is one of the four dominant CrossFit themes.
