I would like to have a personal pov from all the moderators so that we can't give different opinions on the same post, simply because it is not acceptable.
Personally I do not agree completely with Mark suggestion due to my personal experience and tons of clients limitations. Working on HBP elements that requires a free aligned hs in between reps (as a rest position) without a good handstand will strongly reduce the progress over more different elements. Usually here I suggest to spend more time on handstand refinement and mobility rather then progress independently on H1 and HBP.
This is one of the clear point where foundations need the co-requisite of H1.
I think that for a team the first thing is that we need to agree on the fundamentals of GST.
cheers
