Arching off the backrest
Keep your ribs down and lower back near the pad; if you have to arch to finish a rep, drop the weight.

Machine Shoulder Press
The machine shoulder press is a seated overhead press on a guided path, so you can push the front delts and triceps close to failure without balancing a bar or dumbbells. It suits beginners, lifters training alone, and anyone whose shoulders prefer a fixed, supported press.

Muscles worked
The front delts drive the arms up, the triceps finish the lockout, and the side delts help more as the elbows flare out to the sides. Machines with a neutral (palms-in) grip tend to keep elbows forward and feel easier on cranky shoulders.
How to set up
- Adjust the seat so the handles start at or just below shoulder height; too low overstretches the shoulder.
- Sit with your hips and upper back against the pad, feet flat and a little wider than hips.
- Grip the handles with wrists straight and stacked over your elbows.
- Brace your abs so your ribs stay down against the pad.
How to do each rep
- Press up and slightly back along the machine's path until your elbows are just short of locked.
- Keep your head and upper back on the pad; do not crane your neck forward.
- Lower over 2-3 seconds until the handles are back at shoulder level.
- Reset your brace at the bottom instead of bouncing out of it.
Common machine shoulder press mistakes
Half reps at the top
Bring the handles all the way down to shoulder height each rep, using a lighter load if needed.
Seat set too low
Raise the seat so the starting position is not a deep, uncomfortable stretch at the front of the shoulder.
Sets, reps, and progression
Surpass starts the machine shoulder press at 8–12 reps with about 1.5 reps in reserve. As a compound lift it usually belongs early in the session, when you are fresh.
Work in a 6-12 rep range and add one plate or pin once every set reaches the top of the range. When the machine stops feeling challenging relative to your free-weight work, use it for the back-off or high-rep sets.
Know what to lift next time
Surpass shows what you lifted last time beside a target for this set, and adjusts it from your reps and RIR. Free on iPhone, no account needed.

Questions
Is the machine shoulder press good for building shoulders?
Yes. It loads the front delts and triceps through a stable path, which makes it easy to train hard and add weight over time. Add lateral raises if you also want to target the side delts directly.
Machine shoulder press vs dumbbell shoulder press?
The machine is more stable, quicker to load, and safer to take to failure; dumbbells demand more stabilization and let each arm find its own path. Both build the shoulders, so choose based on comfort and equipment.
