The military press is one of the oldest tests of strength there is: standing tall and pressing a weight from your shoulders to overhead using nothing but your upper body and a braced torso. It builds strong, capable shoulders, adds size to the delts and triceps, and teaches your whole body to stay rigid under load. It is also honest. With no leg drive and no bench to lie back on, you cannot hide a weak shoulder behind momentum. Here is how to do the military press properly with a barbell or dumbbells, the muscles it trains, and how to make it a staple of your training.
The classic version uses a barbell, standing with a narrow stance. You can do the same movement with dumbbells.
Bar path and the lean-back trap
The bar should travel in a straight vertical line, which means getting your face out of the way rather than pressing the bar around it. The most common failure is leaning your whole upper body back to turn the lift into an incline press, which strains your lower back. Squeeze your glutes and abs to keep your ribs down and your body upright, and move only your head, not your whole torso.
The military press is a vertical pressing movement, so it is driven by the shoulders and triceps, with the whole body working to stabilise.
The way you press also shifts the emphasis. Studies comparing overhead press variations confirm that grip, equipment and bar position all change how the deltoids and supporting muscles are loaded (EMG analysis of overhead press variations).
Leaning back too far. Turning the press into a standing incline bench press by arching your lower back is the most common and most risky mistake. Brace your abs and glutes and keep your ribs down.
Pressing the bar around your face. If the bar drifts forward to avoid your chin, the bar path curves and you lose power. Tuck your head back as the bar rises, then push it back through.
Using leg drive. Bending and driving with your knees turns a military press into a push press. Keep your legs straight and rigid so the shoulders do the work.
Flaring the elbows. Letting your elbows point straight out to the sides at the bottom stresses the shoulder. Keep them slightly in front of the bar with vertical forearms.
Half locking out. Stopping short of a full overhead lockout cheats the range and the triceps. Finish every rep with straight arms, shoulders shrugged up under the bar.
For strength, work in the 4 to 6 rep range for 3 to 5 sets, adding a little weight when you can hit the top of the range with good form. For size, 3 to 4 sets of 8 to 12 reps works well. Train the military press once or twice a week, resting at least 48 hours between heavy sessions, and always warm up the shoulders first. The NHS recommends muscle-strengthening work for all the major muscle groups on at least two days a week, and one overhead pressing session covers the shoulders neatly.
Pair the military press with pulling work like the bent over row and face pulls to keep your shoulders balanced and healthy, and add lateral raises to bring up the side delts. If you train at home, a squat rack with a barbell makes heavy standing presses safe and simple to set up.
The military press mainly works the anterior (front) and lateral (side) deltoids of the shoulder and the triceps, which straighten your arms overhead. Standing to press also recruits your upper chest, upper back and, importantly, your core and glutes, which brace hard to keep your body rigid as you push the weight overhead. It is a genuine full-body strength exercise built around the shoulders.
They are very similar, and many people use the names interchangeably. The strict difference is stance: the traditional military press is done with the feet together or close, which reduces how much you can lean and drive with the legs, while the standard overhead press is done with feet about shoulder-width apart. The military press is stricter and usually done with a bit less weight as a result. Neither should involve a leg drive, which would be a push press.
Standing is the classic version and trains more of your body, because your core and legs must brace to keep you stable, and standing presses tend to involve the shoulder stabilisers more. Seated presses let you handle more weight and isolate the shoulders by removing the balance demand, which some people prefer for building the delts. Both are valid. If you want the most functional, full-body version, press standing.
It varies enormously with training age, bodyweight and build. As a rough guide, many men work towards pressing around half to two-thirds of their bodyweight for reps over time, and women a little less, but these are only ballpark figures. Far more important than the number is pressing with strict form and adding small amounts of weight gradually. Start light enough to keep perfect technique.
Pressing overhead is safe for most healthy shoulders and is one of the best ways to build shoulder strength, provided you have the mobility to reach overhead without arching your lower back and you progress sensibly. If you have a shoulder injury or cannot raise your arms fully overhead without pain, see a physiotherapist and consider a landmine or incline press instead. Warm up, keep the reps strict, and do not chase weight your form cannot handle.
Once or twice a week is plenty for most people. The shoulders and triceps are also worked by other pressing movements, so one dedicated overhead pressing session, or two lighter ones, fits well alongside bench and pulling work. Give the shoulders 48 hours or so to recover between heavy pressing sessions.
