This video showcases crazy hip and leg flexibility plus amazing hand balancing skills by Ricardo Sosa.
Many people underestimate how much flexibility is needed, or at least is very helpful, in doing many hand balancing stunts. Now you don’t need to be this flexible, but improving your flexibility wouldn’t hurt either.
In fact I know it’s the one thing that is holding me back, more so than strength or skill, to attaining some of the skills I’m going after.
Unless you’re a mutant you won’t be able to get started with these stretches but if you look closely and watch the video a couple times, you may gain some ideas on drills (at a lesser intensity) that you could do.
