Shoulder Press Machine
The shoulder press machine is a seated overhead press along a fixed, guided path, pressing handles from shoulder height to straight arms. It trains the front and side deltoids and the triceps without any balance demand, which makes it easy to load and to take close to failure.
Also called: Machine Shoulder Press, Seated Machine Press, Overhead Press Machine · Equipment: machine · Pattern: push
Step by step
- Adjust the seat so the handles sit level with the tops of your shoulders when you sit down.
- Sit with your back and head against the pad and your feet flat on the floor.
- Grip the handles with your wrists straight and stacked over your elbows.
- Brace your trunk and keep your ribs down so your back stays on the pad.
- Press the handles straight up until your arms are straight.
- Bring the handles back down under control to shoulder height.
- After the last rep, return the handles slowly until the weight stack rests.
- Handles start at shoulder height
- Wrists stacked over your elbows
- Back and head on the pad
- Ribs down, no arch
- Press up to straight arms
- Control the handles back to your shoulders

What goes wrong, and the fix
Back arching off the pad
Fix: Brace with your ribs down and keep your back against the pad throughout.
Seat at the wrong height
Fix: Set the seat so the handles start level with the tops of your shoulders.
Partial reps
Fix: Bring the handles back to shoulder height and press to straight arms every rep.
Wrists bent back
Fix: Keep your wrists straight and stacked over your elbows on every rep.
Head pushing forward
Fix: Keep your head against the pad and let your arms move past it.
What the research says
Muscle growth · first choiceRehab & prehab · first choiceGeneral fitness · first choiceEndurance · first choiceStrength
- Machines and free weights — Randomised trials in trained lifters found machine and free-weight training produced similar muscle growth, while strength gains were specific to the equipment trained on.
- Muscle activity — An EMG study in trained men found barbell overhead pressing produced more deltoid activity than a machine press, as the machine's fixed path takes over some of the stabilising work.
- Load by goal — Research comparing loads finds maximal strength favours heavier loads, while muscle growth is similar across a wide range of loads when sets are taken close to failure.
- Effort — Studies show sets that finish a few reps short of failure capture most of the size benefit. A guided machine is a common choice when lifters take sets closer to failure without a spotter.
- Volume and frequency — Research links more weekly sets for a muscle to more growth, with diminishing returns, and training a muscle about twice a week is a common way to spread that volume. A common approach is 3–4 sets of 6–15 reps.
