I am at the wall handstand progressions, but can't shake the feeling that I'm unable to reach proper form because of my bad shoulder mobility. However much I squeeze the PPT, I get out of every set with lower back pain. I'm assuming that's my lower back compensating for terrible shoulder flexion. Should I keep doing the progression and hope that that takes care of the shoulder flexion over time, or is there some other mobility that I can do to get to 180 degree shoulder flexion from what is right now more like 140 degrees? I've been doing the shoulder restore series for a long time, but it hasn't helped the flexion whatsoever. Any other ideas?
Thanks a lot!
