Equipment

Pattern
Shoulder horizontal abduction
Setup
- 01Set the seat so the handles sit at shoulder height.
- 02Sit chest against the pad facing the machine.
- 03Grip the handles with arms extended forward.
- 04Soften the elbows and pull the shoulders down.
Execution
- 01Open the arms out to the sides in a wide arc.
- 02Lead with the elbows, not the hands.
- 03Stop in line with the torso while squeezing the rear delts.
- 04Return slowly under control to the start.
Checkpoints
- -Elbows stay slightly bent throughout.
- -The chest stays pinned to the pad.
- -Rear delts drive the movement, not the traps.
- -The arc stops level with the body, not behind it.
Common mistakes
- -Shrugging and letting the upper traps take over.
- -Bending and straightening the elbows like a row.
- -Using momentum to fling the handles open.
- -Going too heavy and losing rear-delt tension.
Programming notes
- -Use 3 to 4 sets of 12 to 20 reps.
- -A brief squeeze at the open position improves the stimulus.
- -Pair with lateral raises and pressing for balanced shoulders.
