The "Hip Hinge" (or the athletic ready position) has been called the most important sports movement. There are many ways to teach the hip hinge. I prefer teaching it using a light two-pound "SandBell" disc. Due to some recent inquiries, here's a fairly detailed explanation of how I teach the Hip Hinge with SandBells plus a link to one of my videos on this topic for further review.
