Functional training is more than just building muscle.
“The main word here is function. Function movement has real purpose.
So functional training is just training that has a purpose. Functional training is focused on movement patterns that have a purpose.
That purpose can be related to getting better at everyday activities—like walking, squatting to pick up something heavy, pushing a revolving door, or getting in and out of a chair—or preparing to compete in a sport, like soccer, football, or tennis. A functional workout is simply one that strengthens you in a way that directly translates to an activity outside the weight room. For most people, the practical application of functional training is to make daily activities easier to perform.
