The deltoid muscle uses a third-class lever system when abducting the arm. In this system, the effort (contraction of the deltoid) is applied between the fulcrum (the shoulder joint) and the load (the weight of the arm). This arrangement allows for a greater range of motion and speed of movement, although it requires more effort to lift the arm compared to other lever systems.
