Beth Bischoff Lean your head, upper back, and butt against the wall. (A) Place your hands and arms against the wall in the "high-five" position, your elbows bent 90 degrees and your upper arms at shoulder height. Hold for 1 second. Don't allow your head, upper back, or butt to lose contact with the wall. Keeping your elbows, wrists, and hands pressed into the wall, slide your elbows down toward your sides as far as you can. Squeeze your shoulder blades together.
