We are working on the posterior chain today: posture, hammies, lumbar curve. I often get asked how to mobilize the lower back. This is a hard question because your back pain is usually caused by something else. Has your back ever hurt after doing deadlifts? Or box jumps? This might not be because of direct impact on your back, but of an elusive little booger called your psoas. You have to mobilize it through the torso, so it may be counterintuitive to the posterior chain although it's anatomical connections can yank on lots of stuff. Get to know this guy because it can contribute to rotated/tilted hips, back pain, and worst of all, overextension. Overextension is the reason you can’t get into THE position, the hollow. Loading your body up day after day in a compromised position can do some damage over time.

We are going to stick with posterior chain basics in classes today. But consider mobilizing your psoas as well. Now everyone will know you're mobilizing, not humping the floor. So have at it!
