I've just started working this, with feet on straps and rings very close to the ground. I'm reasonably stable.
I can do 3-5 headstand pushups against the wall, and can hold a free handstand (when I'm lucky) for 10s.
I don't have anywhere near the strength to press from shoulderstand to handstand. Anyway, I plan to keep working headstand pushups until they get to full rom.
In the meantime, is it productive to press (isometrically, since I'm not strong enough to move) while in shoulerstand position on the rings, just to start working on strength in that position? If so, what would be the best way to program it?
Thanks for any advice!
