When I do these movements, and with the lightest band I have, by the 8th to 10th rep range my left shoulder basically gives out. By gives out, I mean it feels like it comes out of place; dislocates, and in the bad sense (not the warm-up movement by the same name). The lightest band I have is yellow in this package of bands I bought and is about 2-5 lbs I believe in resistance. In any case, yes I stop doing the movement at this point. I also realize that this is likely an issue of strength, in that I'm lacking it in my shoulders. Being that I'm using the lightest weight band for the exercise....I'm not sure how to go about strengthening my shoulders while still working on this movement pattern.
I relish the day when I can do a handstand, but these shoulders...I'll tell ya. I would have never thought that I was this tight up until I started doing this program.
