Sit or stand at a lever chest press machine and grasp the single handle with one hand at shoulder level. Keep your torso stable and core engaged. Push the handle forward and slightly upward until your arm is extended, focusing on contracting the chest and triceps. Pause briefly at full extension, then slowly return to the starting position with control before repeating and switching sides.
