This is a total body movement the strengthens the hips, rump, legs, and shoulders. It moves the body through all of the primary motions - hinge, squat, push, and pull.
Start with the feet just slightly wider than hip width apart. Press the rump back, hingeing at the waist, to reach down and touch the toes. Bring the hips forward and return to standing tall. Next, sit down into a squat by bringing the elbows between the knees. Return to standing tall and press the hands overhead while coming up. That is one repetition. Complete one set of 10 repetitions.
