Good posture

Rarely is physical therapy funny. But with movement and mobility guru Kelly Starrett at the helm, laughs are guaranteed.

During the CrossFit Experience at the 2012 Reebok CrossFit Games, the doctor of physical therapy talks about good posture and how it translates to athleticism.

"I want you to take a huge breath in your belly—big breath. Hold it. Now get tight. How's that workin' for ya?" he asks the crowd. "It's like putting a bounce house into a little duffle bag, isn't it? It's never gonna work."

The butt sets the pelvis, which is the body's source of power, says Starrett, founder of San Francisco CrossFit. The pelvis needs to be in a neutral position to avoid overextension.

"If you're disorganized or in a bad position, things don't turn on," he explains. "If you're in a good position, things turn on."

Starrett asks the group to put their arms straight overhead as if they were swinging a kettlebell.

"In order to control the spine, I have to think about what's happening at the pelvis," he says. "So if I have to control my shoulder-ribcage relationship, that's got to start at the pelvis."
