Push-Up Stands / Handles - $5 These protect your wrists during push-ups by ensuring good hand and arm position; just doing push ups on the floor puts high PSI (pounds per square inch) pressure on your wrists at an unnatural 90 degree which your wrist muscles can't protect your joints properly at. Simple, easy to store, and necessary for the push-up portion of your workout. New varieties retail for anywhere from $15 to $60. I have two sets and my workout partners have grown up and moved out.
