Isolate – Integrate – Improvise

I believe you have to isolate basic movement patterns creating a pain free, mobile and stable platform for your body to effectively build skill and complexity, whether it is running mechanics, a squat or handstands. Once you have efficient isolated patterns you can start to add and integrate load and complexity through a hierarchy of progressions meant to continually add stress so the body will adapt. The end goal is to be able to improvise. By this I mean to interact fluidly and efficiently with your surroundings, whether it is a running back in a football game, an Olympic lifter doing a clean and jerk or something as simple as bending over and picking up groceries.
