I'm having trouble getting my HS/PE6 mobility, the underhand shoulder dislocations, to look like the demo video. At least I think -- the angle of the demo video may be misleading. My version looks basically like this guy's: https://youtu.be/ATDzViZ4jzQ?t=1m6s , with the hands/wrists looking all twisted up when they come to the front. To my eye, the demo video doesn't look like this... Assuming it's not, any suggestions on how to get to the good way? Thanks.
