Forget posterior chain, glute medius, transverse abdominis and all those other reductionist, mechanistic ways of looking at the body. Instead, step back and look at the whole kinetic chain. Look at how everything is connected. Look at how the parts interact and work in synergistic patterns to solve movement problems. To analyze motion look at how everything links, syncs and coordinates. See if there is a flow, a rhythm that allows natural use of gravity and ground reaction forces to produce or reduce force. Look at movement as a big dance with varied rhythms and tempos. Look at how all systems of the body work together continually to produce efficient movement. Just like it is futile to isolate muscles the same is true with trying to isolate systems of the body. Everything is neural everything is metabolic. Read more
