Machine Shoulder Press
Also known as: machine military press
A fixed path and a full back pad strip away the balance demands that make free-weight overhead work slow to learn, so you can focus purely on pushing hard. Set the seat so the handles start at ear height, not down at your collarbones. It also lets you train within a rep of failure without a spotter.
How to do the Machine Shoulder Press
- Adjust the seat height and position yourself on the machine with your back against the backrest.
- Grasp the handles with an overhand grip and position your hands slightly wider than shoulder-width apart.
- Push the handles upward until your arms are fully extended, but do not lock your elbows.
- Pause for a moment at the top, then slowly lower the handles back down to the starting position.
- Repeat for the desired number of repetitions.
Tip: Take a breath and brace before unracking, then press up and slightly back so the bar ends over the middle of the foot.
Muscles worked
Primary
Delts · Shoulders
The front and side delts drive the weight off the shoulders and should carry the load all the way to lockout; the burn builds across the whole shoulder cap.
Common mistakes
- Leaning back into an incline — if the lower back arches hard, the chest is doing the work; squeeze the glutes, brace the abs and keep the ribs down.
- Pressing around the head — the bar should travel straight up, so pull the chin back to let it pass, then push the head through at the top.
- Stopping short of lockout — finish with the arms straight and the bar stacked over the shoulders and hips, shoulders shrugged slightly up at the top.
- Elbows drifting behind the bar — keep the elbows slightly in front of the bar at the bottom, with the wrists stacked straight above them.
Sets, reps and where it fits
| Goal | Sets × reps | Rest |
|---|---|---|
| Strength | 4–5 × 3–6 | 2–3 min |
| Muscle growth | 3–4 × 6–12 | 90–120 s |
| Endurance | 2–3 × 12–20 | 60 s |
Overhead presses go first in a shoulder session or second after bench in a push day. Superset them with a pulldown or pull-up for a vertical push and pull pair.

Frequently asked questions
What muscles does the Machine Shoulder Press work?
The Machine Shoulder Press primarily works the delts. It also involves the triceps and pectorals, which assist the movement and stabilise the joints.
Is the Machine Shoulder Press good for beginners?
Yes. The Machine Shoulder Press is rated beginner: it uses a machine and the movement is simple to learn. Start light, focus on the full range of motion and add load once every rep looks the same.
What can I do instead of the Machine Shoulder Press?
If you cannot do the Machine Shoulder Press, try the Iso Lateral Machine Shoulder Press, the Foot Assist Machine Shoulder Press or the Single Arm Landmine Shoulder Press. Each of them trains the delts through a similar movement, so you can swap them in without changing the rest of the workout.
How many sets and reps should I do?
It depends on your goal. For the Machine Shoulder Press, a sensible starting point is strength: 4–5 × 3–6 with 2–3 min rest; muscle growth: 3–4 × 6–12 with 90–120 s rest; endurance: 2–3 × 12–20 with 60 s rest. Put it early in the session while you are fresh, before isolation work for the same muscles.
