This video shows a man doing 5 ring handstand push-ups. Can you do this too? I could probably do one or two reps right now if I tried.
The ring handstand pushup takes much more strength then even full range handstand pushups against a wall. Although the straps can be used so you don’t have to balance, the strength it takes to stabilize your body dramatically increases.
It would also be smart to work the shoulder stand position on the rings at the bottom.
