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.”
