The landmine press is one of the best pressing exercises for people whose shoulders complain about a strict overhead press. You anchor one end of a barbell, hold the other end at shoulder height, and press it up and forward along an angled arc. That path keeps your arm in front of your body rather than forcing it fully overhead, so you build strong shoulders and an upper chest without the pinch that overhead work can cause. It is also a superb core and stability exercise, especially done one arm at a time. Here is how to do it properly, the muscles it works, and how to make it a staple.
Set up by anchoring one end of a barbell in a landmine attachment or a secure corner, and load a plate on the free end. The half-kneeling single-arm version is the best place to learn.
Do not let your back arch
Because you press up and forward, it is tempting to lean back and arch your lower spine to help the weight up. That shifts the work off your shoulders and stresses your back. Squeeze your glutes, keep your ribs pulled down, and press with a tall, stacked torso. If you have to lean back to finish a rep, the weight is too heavy.
The landmine press is a compound push with a big stability demand.
Training your shoulders and chest a couple of times a week fits the NHS advice to work all major muscle groups on at least two days a week.
Arching your lower back. Leaning back to muscle the weight up stresses your spine and takes the shoulders out of it. Brace your abs, squeeze your glutes and stay stacked.
Flaring the elbow wide. Letting your elbow drift far out to the side stresses the shoulder. Keep your elbow tucked in front of your body and press along the bar's natural line.
Pressing with your legs. In the half-kneeling version, bouncing your hips to help the press defeats the purpose. Keep your hips locked and let your shoulder do the work.
Cutting the range short. Not locking out or not returning fully to the shoulder shortchanges the movement. Press to a straight arm and lower all the way down.
Uneven sides. Doing more reps or more weight on your stronger arm builds in an imbalance. Match your reps and load on both sides.

A simple plan that works for most people:
Add a little weight once you can hit the top of your rep range with clean form on both arms. A barbell, weight plates and a landmine point will keep you progressing for a long time.
The landmine press mainly works the front deltoids (shoulders) and the upper chest, with the triceps helping to straighten the arm. Because the bar travels up and forward on an arc, the serratus anterior around your ribs and your core work hard to control the movement, which is why it feels like a whole upper-body pressing exercise.
The bar moves on an angled path, up and slightly forward, rather than straight overhead. That keeps your arm in front of your body instead of forcing it into full overhead reach, which is where many people feel shoulder pinching. For anyone who finds a strict overhead press uncomfortable, the landmine press is often a friendlier way to train the same muscles.
It is mostly a shoulder press with a strong upper-chest contribution, so it sits between the two. The angled pressing path means your front deltoids and the top of your chest share the load. You can shift the emphasis a little by changing your body angle, but treat it as a shoulder and upper-chest builder.
It helps but is not essential. A landmine attachment that pins one end of the barbell is the most secure option, and many power racks have a landmine point. If you do not have one, you can wedge the end of the barbell into a corner with a towel to protect the walls, though a proper attachment is safer and smoother.
Both work. The half-kneeling landmine press, with one knee down, removes momentum from your legs and forces your core to stabilise, so it is great for strict single-arm work and fixing imbalances. The standing version lets you use a little leg drive and press heavier or with both hands. Beginners often start half-kneeling to nail the path.
For strength and muscle, 3 to 4 sets of 8 to 12 reps per arm (or total, if pressing with both hands), two or three times a week, works well. Keep the reps equal on each side for single-arm work. Rest 60 to 90 seconds between sets.
