Fundamental Capacity Screen: A Gray Cook Interview with Cody Dimak

What’s the next movement screen?

In this interview with Cody Dimak (and featuring a surprise appearance by Phil Plisky), Gray Cook dives deep into he wants to screen after movement is functional. This is an overview of the new FMS Fundamental Capacity Screen—the FCS.

“The cleaner, quicker, and more valid we can make the test, the better techniques and exercises will emerge. It’s not the other way around. We try to introduce better techniques and exercises, yet without a baseline, we’re going to be missing something. I don’t care if it’s my baseline or somebody else’s, but we get a baseline and then we start bouncing all this innovation off of it.” ~Gray Cook
