People have been asking me what I mean by more left arm rotation and how does that differ from rolling the wrists or forearms.
Here you go.
Stand straight up and down and extend your left arm away from you with your palm down and your left elbow pointed left of you. Now rotate your arm so the back of your left hand is pointed left of you and your elbow is pointed down.
That is the move that will keep you connected and give you a gradual release.
