I've got some decent control in the handstand with just doing attempts but my progress is stalling now. My max hold time is 20 seconds and usually I get the perfect stacked position but other times my feet are out of line behind my back and I am not aware of that during the hold. I feel I really wack awareness and control outside the thin balance window and this makes my HSPU balance very inconsistent. How do you guys suggest I train at this point to make further progress - shoud I do just holds, drills, experiment with shapes or smth? I would appreciate some cues how to incorporate this in my split - pull push rest repeat.
