Join Kelly Starrett, owner of San Francisco CrossFit and creator of MobilityWOD, as he teaches coaches and their athletes how to diagnose dysfunction.

In Part 3, Starrett shares positioning strategy. An organized set-up for good start position leads to a good finish position, and you don’t have to focus on what happens in between, he says.

“Once you’ve lost position or surrendered that position of dominance or that organization, you cannot reclaim that good position, so it’s lost potential,” he says.

Starrett’s “One-Joint Rule” is employed to stabilize as much of your body as possible so that one joint is primarily responsible for the movement.

“What we want to try to do is reduce the number of variables in the spine and reduce the number of variables out in the joint to just stabilizing at the prime mover,” he says.

Another application of the One Joint Rule is that joints are similar, so they should move in the same ways.

“If I understand how the hip joint works, I understand how the shoulder joint works and that they’re approximately the same joint,” Starrett says.

“Most of the downstream issues of elbow and wrist and ankle and knee are resultant from faults that arise much closer to the trunk,” he says. “And so if I can control the trunk and then control for the position of the primary one joint, then a lot of the other mechanics clean themselves up automatically.”

For some reason I don't have tags for this file visible in iTunes, so no Album, no Artist etc. :) It would be cool to have them back again - I'm using automator to add files from CFJ to my iTunes library and sync them to iPad.
Thanks !

Absolutely genius. Starrett has helped me understand proper joint mechanics at the hip/shoulder in a way that would've taken me years of painful trial and error to uncover. Thank you!!

The point about starting and finishing position is key stuff that applies across the board of human movement on a daily basis, not only in sports performance or training. I use functional formal movements and movement analysis to detect where a client in musculoskeletal pain is "giving out" i.e. compromised from the start by a non optimal posture or movement pattern......if that movement pattern is not checked then the eventual effects ripple exponentially through the system like a butterfly effect - slight dysfunction in the centre is expressed in gross "off-track" patterns at the periphery - eg shoulder to elbow to wrist....

These "off-track" patterns are and should be used as signs that the "one joint" is no longer operating as one.....if left unchecked, the one joint/centre itself will become the victim of pain and mechanical dysfunction -

look for clues you bodyworkers, before the slightly dysfunctional centre becomes grossly so.

GREAT stuff by Kelly here - underlining good, basic and essential things. Loving it!!
