Waist corners and hold the hip down firm. With the hip kept down firmly the muscles at the extreme corners of the back can be initiated. But there is no guarantee that the muscles that are on either side of the spine (paraspinal) get initiated with by just initiating the waist corner. The paraspinal muscles are the “action” muscles of the back. When they work, the result is the obvious movement of your spine. They course down your back and spine and help to move your spine into extension, rotation, and side bending. In this session we access those paraspinal muscles by initiating with the use of the belt.
