1. Wide to Narrow Push-Up
    Depending on your strength you can either start in standard push-up position or modified (with your knees on the floor). Begin the wide to narrow push-up with your arms wide and your hands shoulder width apart. Do a push-up, and then move your hands in towards the center so they are closer together, almost in a tricep push-up position. Go down, then push back up, and then alternate moves for one minute.
