How to Perform
- 1
Adjust the seat, pads, and handles so the machine aligns properly with your joints. Proper setup prevents injury and ensures the target muscle does the work.
- 2
Brace your body against the pads to isolate the target muscle. Grip the handles or position yourself as indicated.
- 3
Move through the full range of motion with deliberate control. Focus on the squeeze at peak contraction.
- 4
Return to the starting position slowly — the eccentric phase is where significant muscle damage and growth occurs.
Common Mistakes
Using too much weight and turning a raise into a shrug. Your traps should not be doing most of the work.
Raising above shoulder height, which shifts stress to the traps and can impinge the shoulder.
Locking the elbows completely straight, which stresses the joint. Maintain a slight bend throughout.
Pro Tips
Lead with your elbows, not your hands. Imagine pouring a glass of water as you raise — this keeps the tension on the delts.
Use lighter weight than you think you need. Delts respond exceptionally well to higher reps (15-20) with strict form.
