I think wall sits are best for you. You should try it.
I dont think you right
The problem is, that there is no rly good gyms. Not enough ppl looking for the same... So not enought demand
I am agree. U need just try to focus. And continue practice. Ask a coach for some advise. Try to do what he says. Maybe it will help you.
I think so too. Try to improve it. And it will be better now
