Often see the "glove/headcover under left armpit drill" and have found it to be helpful in my pre -TGM days. Should this feeling of connection be present whilst "swinging"?
When I try to swing, with pitch elbow position, i sometimes feel that there is minimal connection between left upper arm and chest. It gives me a loose-limbed feeling with little tension or conscious "hit" but ball striking is inconsistent.
It seems to occur if my left shoulder rises too early and my shoulders rotate too early on downswing? The only way I can create that feeling of connection is by delaying shoulder downswing rotation - along the lines of keeping back to target longer in downswing.
