The human deltoid muscle is divided into three bundles: anterior, middle and posterior. The instrument can effectively exercise the middle and front bundles, but it has basically no exercise effect on the rear bundle of deltoid muscle. This kind of equipment usually has different handles and the height of the seat can be adjusted. Through these adjustments, you can choose the range of motion, as well as toe-in and toe-in.
