The wall push-up is a great exercise for beginning to weight bear through your wrists, which is important for preventing further bone loss in that area. The wall push-up also strengthens the muscles of your upper body, including your chest, shoulders, and arms.
Begin by standing about a foot away from a wall. Facing the wall, place your hands on the wall at about shoulder height.
Bend your elbows in a push-up position. Straighten your elbows, pushing yourself back to the starting position.
