The Cybex VR3 Lateral Raise is a machine designed to train specifically the medial deltoid. The position of the medial deltoid varies from person to person & most lateral raise machines are not designed to capture these differences. However, Cybex has engineered the Lateral Raise to align the muscle with the movement so that the expected muscle is trained. The machines padded arms are slightly angled to encourage neutral shoulder position & to eliminate external rotation (undesirable in this movement), whereas the floating handgrip helps to target the forearm & provides consistent positioning.
