Landmine Single-Arm Press

Body Part: Shoulders

Muscle: Chest

Equipment: Barbell

Landmine Single-Arm Press is a standing pressing exercise that drives a barbell along a fixed diagonal path. The landmine setup makes the press feel more shoulder-friendly than a strict vertical overhead press because the arm travels forward and up instead of straight overhead. That angle still trains the shoulders hard, but it also asks the triceps, upper chest, serratus, and trunk to keep the rep smooth and controlled.

The exercise is useful when you want pressing strength without the same shoulder position demands as a full overhead press. The working side has to stabilize the bar path while the torso resists rotation, so the movement trains force production and anti-rotation control at the same time. In practice, that means you should feel a strong press through the shoulder and triceps with the core and upper back staying organized so the bar does not drift off line.

Setup matters more here than on many machine presses. Stand with the landmine sleeve anchored securely, the working hand holding the end of the bar at about shoulder height, and the body slightly staggered or split so you can brace without leaning into the weight. Keep the rib cage stacked over the pelvis, let the free arm balance naturally, and start every rep from a stable shoulder position before you drive the bar upward along the arc.

Press the bar up and forward until the arm reaches a strong, controlled finish without shrugging hard or twisting the torso. Lower it back to the shoulder under control and keep the path clean on every repetition. If the load is too heavy, the bar will swing away from the torso, the trunk will rotate, and the shoulder will lose its clean pressing line. The best set feels stable, repeatable, and powerful rather than rushed.

This movement fits well in upper-body strength work, hypertrophy blocks, or accessory sessions for athletes who need pressing strength with less overhead stress. It is also a practical option for lifters who want to train one side at a time and expose side-to-side differences in shoulder control. Keep the repetition quality high, switch sides deliberately, and stop the set when the press turns into a body English-driven heave.

Instructions

• Anchor one end of the barbell in a landmine base and stand facing the bar with your working side nearest the sleeve.
• Take a staggered or split stance so you can brace without rocking, and keep your feet flat and planted.
• Grip the end of the bar with one hand and bring it to shoulder height with your elbow slightly in front of your body.
• Set your rib cage over your pelvis, tighten your midsection, and keep your free hand relaxed for balance.
• Press the bar up and forward in a smooth arc until your arm is nearly straight and your shoulder stays packed, not jammed.
• Do not lean back or twist to finish the rep; let the bar travel while your torso stays mostly square.
• Lower the bar back to shoulder height under control, keeping the path steady and the elbow under the hand.
• Exhale as you press, inhale as you lower, then repeat for the planned reps before switching sides.

Tips & Tricks

• Keep the bar path slightly forward and upward; if it moves straight out in front, the press usually turns into a shoulder and trunk compensation drill.
• Use a split stance when you need more balance, especially on heavier sets or when the bar wants to pull you off center.
• Let the elbow travel just in front of the torso at the bottom so the shoulder can press from a strong line instead of being forced wide.
• Do not finish by arching your lower back; the ribs should stay stacked so the press comes from the shoulder, not from a lean.
• If the top half gets shaky, reduce the load and own the final third of the arc before adding weight.
• Keep the free hand quiet rather than swinging it for counterbalance, which can hide torso rotation.
• Lower the bar slowly enough to keep tension in the pressing side, but not so slowly that you lose the clean line of the rep.
• Stop the set when the shoulder shrugs, the torso rotates, or the bar starts bouncing off the bottom position.

Frequently Asked Questions

What muscles does the Landmine Single-Arm Press work?

It primarily trains the shoulder on the working side, with strong help from the triceps, upper chest, serratus, and core.

Why use a landmine press instead of a strict overhead press?

The diagonal bar path is usually easier on the shoulders and lets you press hard without requiring a fully vertical overhead position.

How should my body be positioned during the press?

Stand in a staggered or split stance, keep your ribs stacked over your pelvis, and avoid twisting as the bar moves.

Where should the bar start before each repetition?

Start with the end of the bar at shoulder height on the working side, with the elbow slightly in front of the torso.

Should I lock out hard at the top?

Reach a strong finish, but do not jam the shoulder or overarch the lower back to force extra height.

What is the biggest form mistake with this movement?

Leaning back or rotating the torso to help the press is the most common breakdown, especially when the load is too heavy.

Is the single-arm version useful for core training?

Yes. One side has to resist rotation while the other side presses, so the core works hard to keep the torso stable.

How do I progress the Landmine Single-Arm Press?

Add small amounts of load, tighten the rep path, and keep the torso quieter before pushing for more weight or volume.
