holding the h bar and swinging your legs so you land holding the bar around your waist
No offense intended, but I'm a level 9 gymnast and I didn't even understand what you meant by that answer :/. So I will try to clarify.
1. It doesn't matter what kind of bar you are on
2. you start in a front support (if you dont know what that is look it up online)
3. bend at your hips around the bars and then swing then away from the bar to start your swing
4. using your momentum glide all the way up to hand stand
That was probably a much longer answer than you wanted but... now you know.
