I haven't progressed to this PE in H1 but would like to get a form check because I'm doing wall handstands as part of Stretch. So it's not much weekly volume but I'd like to do the S exercise with as good a form as possible.
I think I need to get my shoulders more open (more flexion). Also focusing on shrugging and protracting. How's PPT etc.? Doing H1 iMs 9 and 10 helped me a lot to improve PPT.
