Hi,
I've just started working on standing overgrip dislocates and am having trouble figuring out the correct technique. I'm finding that I can do the dislocate quite easily with my hands reasonably wide apart, but that as my hands come behind my back, my shoulder doesn't fully rotate and I lose the grip with my outer fingers (pinky, then third, then second) so I'm no longer gripping the bar with my whole hand. Below is an example YouTube clip where the guy does the same thing as me (actually his is more extreme):
From about 18 seconds you can see that he does the dislocate, but when his hands are behind his back he is only holding the bar with his first finger and thumb, not with a full grip. In most of the vidoes I can find including the GB ones, people are holding with a full grip for the whole time.
My question is, does this matter? and if it does, what's the cause and how can I fix it?
Many thanks!
