Shoulder extensions

Hi all

I was just wondering if shoulder extension help with the HS/PE2>iM

I started training shoulder extensions on and off a few months back.

I noticed the HS/PE2>iM so had a go and could raise almost level so was thinking that this may have helped or do they have no connection at all?

The shoulder extension it is the basic range of motion of more advanced dislocate variation. shoulder girdle control like all the stabilization movement must be built up before with isometric then with dynamic movement, before with partial rom and then with full range of motion.
