@hypertrophycoach: Free course in my bio: 11 tips from training 11 Olympia champions. Rear delt cable raises and the 45 degree myth, Joe Bennett on which arm angle trains your rear delts. Somebody made up that the fibers run at 45 degrees so your arm has to be there; the rear delt crosses the shoulder joint and follows the humerus, so with the cable lined up with your arm a whole range of heights works, and the thing to listen to is your shoulder joint, not a diagram. The one reason to go higher is isolation, because the lower you go the more your lats can help. #reardelts #reardeltraise #shoulderworkout #delts
