Walk on Your Hands
Once you get comfortable with handstands start walking laterally along the wall with your feet still in contact with it. Eventually, once you master your handstands you can start walking without the wall. In the meantime, slap a Power Wheel on your feet and walk up and down the gym floor or across a field. A great goal to shoot for is being able to walk 100 yards on your hands. You can make hand walking even more challenging by doing Alligator pushups with the Power Wheel . Any type of dynamic range of motion exercise like this that has you moving positions on each rep is great for strengthening the shoulders.
