To start with I'll say I have very poor mobility on the shoulder and I definitely want to improve that (I cannot even reach half the way up in a wall slide), cause it affects me in all overhead work. This seems to be a good exercise for this purpose.
So I've been reading the posts about form check on this exercise and seen the demo video dozens of times now, and each time I see it the more the more I'm sure the lad dislocates a bit the shoulders (his elbows pit come a bit from facing each other to face forwards). In the forum people actually encourage not to dislocate the shoulders at all, so keep elbow pits facing each other. The feeling from one style to the other is totally different
On the other hand people seem to agree that keeping flat back and ribcage down is the way to go.
So, any acclarations on the shoulder form?
Thanks
