Today’s mission is going after two goals:
1) When I see athletes in the clinic with extension based back pain, those athletes rarely know how to stand effectively.
2) We’ve got to better understand the relationship of the stabilizing effects of limb torque (primary engines of hip/shoulder) and the the trunk. In order to effectively generate force and control the hip and shoulder, the trunk must be well organized and can be thought of as a “chassis” or ”frame” on which the primary engines are mounted. But, the relationship extends the other direction as well. Torque force generated downstream at the hip and shoulder make for a stable pelvis and rib cage (off of which the rest of the trunk can stabilize). The bottom line is, you need both a rock solid trunk (or core/spine) and limbs that are positioned to create optimal torque (this is why we squat with the feet between 5 and 12 degrees for example).
