I am working on perfecting the PE2 handstand exercise. The problem that I think I have with this exercise is the "balance". But I am not sure if it is a balance thing (so I need to focus on my brain training) or a lack of strength of my core (or some other part). My height is 188cm (approximately 6.2"). When I am trying this exercise, I usually stand for a little bit and then I fall... I can't control the time that I stay, sometimes I stay only for 6 seconds and sometimes I am finding the correct "spot" where I can stay even for 60 seconds. I thought to go back on PE1 but I can do it comfortably up to 3 minutes and I am finding the correct spot everytime.
So, my questions are:
1) Is it a problem of strength or is there a balance "thing"? If it is a strength problem, then I should focus on my core and foundation one?
2) If there is a balance thing, should I just keep doing it until my brain learn to find the correct spot immediately and more often? I was thinking to start doing it on the wall and start slowly bringing my legs away, is it a bad idea? Or is it better to start working it with my legs not fully extended but on the knees (and raising them a little bit each time)?
3) I am trying this exercise every day and I don't fill sore, but is it a bad approach?
