How many times do we see people in the gym lifting their elbows during these shoulders movements? When the elbows come up there is a loss in resistance due to gravity. Also, when the elbows come up, the full extension is lost, so the bottom of the shoulders muscle will not be hit with the movement.
Too few weightlifters in the gym pay attention to wrist position while performing shoulders lifts. In order to achieve results from training, emphasis must be kept on this muscle during the lift. But, when the wrist is bent backward, some emphasis will be taken off the shoulders muscle and shifted to the forearms.
While most bodybuilders will have varying opinions on the most efficient shoulders exercise, many will agree that you should never sacrifice form for weight. Incorrect form hinders progress because it leads to injury. Low back problems, tennis elbow tendonitis can become injury factors when an improper form is sacrificed to heave heavier weights.
