Landmine Single-Arm Press: Form, Muscles Worked, Sets, Tips & FAQ

Shoulders

Landmine Single-Arm Press

Beginner to Intermediate Barbell + Landmine Attachment Shoulders / Upper Chest / Core Stability

The Landmine Single-Arm Press is a shoulder-friendly unilateral pressing exercise that trains the anterior deltoid while also involving the upper chest, triceps, and core stabilizers. Because the bar travels on an angled arc instead of straight overhead, this variation can feel smoother on the shoulders while still building pressing strength, shoulder control, and anti-rotation stability.

This movement is ideal for lifters who want to build pressing strength with a more natural bar path. Since you work one arm at a time, the exercise also challenges your torso to resist twisting, making it useful for improving coordination, side-to-side balance, and total-body control. Keep the rep smooth, stay tall through the torso, and press the bar up and slightly forward rather than trying to force it into a straight overhead line.

Safety tip: Stop the set if you feel sharp shoulder pain, pinching at the front of the joint, or excessive lower-back arching. Use a load you can control without leaning back or rotating through the torso.

Quick Overview

Body Part	Front Shoulders
Primary Muscle	Anterior deltoid
Secondary Muscle	Upper chest, triceps, serratus anterior, obliques, and core stabilizers
Equipment	Barbell, landmine base or corner setup, weight plates
Difficulty	Beginner to Intermediate

Sets & Reps (By Goal)

Muscle growth: 3–4 sets × 8–12 reps per side
Strength: 4–5 sets × 4–6 reps per side
Technique and control: 2–4 sets × 6–10 reps per side with a slow tempo
Warm-up activation: 2–3 sets × 10–12 light reps per side

Progression rule: Increase weight only after you can press both sides with the same smooth path, stable torso position, and no compensatory lean.

Setup / Starting Position

Set the bar: Place one end of a barbell in a landmine attachment or secure corner setup.
Stand tall: Position your feet about shoulder-width apart for a stable base.
Grip the sleeve end: Hold the loaded end of the bar with one hand at shoulder level.
Elbow position: Keep your elbow slightly in front of the body, not flared straight out to the side.
Brace the core: Tighten your abs and glutes to prevent leaning back during the press.
Keep the wrist stacked: Maintain a neutral wrist so the hand stays directly behind the bar.

Tip: A staggered stance can help some lifters feel more stable, but a square stance works well if you can resist rotation cleanly.

Execution (Step-by-Step)

Start from the shoulder: Begin with the bar close to the front of the shoulder and the torso upright.
Drive the bar up and forward: Press along the natural diagonal landmine path until the arm is nearly straight.
Keep the ribs down: Avoid excessive lower-back extension as the bar rises.
Stay square: Do not rotate the torso toward the working arm.
Pause briefly: Control the top position without shrugging excessively.
Lower with control: Bring the bar back to shoulder level smoothly and repeat for the target reps before switching sides.

Form checkpoint: The bar path should feel like a clean diagonal press, not a strict overhead press and not a chest throw. Think “press through the shoulder, stay tall, resist twisting.”

Pro Tips & Common Mistakes

Press on a diagonal path: Let the landmine guide the bar instead of forcing it vertically.
Do not lean back: Excessive backward lean shifts stress away from the shoulder and into the lower back.
Keep the core engaged: The torso should resist rotation throughout every rep.
Do not flare the elbow too wide: A slightly tucked pressing angle is usually stronger and more shoulder-friendly.
Control the eccentric: Lowering the bar slowly improves stability and keeps tension on the target muscles.
Use even reps per side: Match volume left to right to reduce side-to-side imbalances.
Start lighter than you think: Unilateral landmine pressing often feels harder than bilateral pressing because of the stabilization demand.

FAQ

What muscles does the Landmine Single-Arm Press work?

It primarily targets the front deltoid, while the upper chest, triceps, and core stabilizers assist during the press.

Is the Landmine Single-Arm Press better than a dumbbell shoulder press?

Not necessarily better, but different. The landmine variation offers a more angled pressing path that many lifters find more comfortable on the shoulders, especially if strict overhead pressing feels awkward.

Should I do this exercise standing or half-kneeling?

Standing is great for full-body coordination and anti-rotation control. Half-kneeling can be useful if you want more core focus and less chance of compensatory leaning.

How heavy should I go?

Start with a load you can move smoothly without torso twisting, rib flare, or lower-back arching. Clean mechanics matter more than loading the bar aggressively too soon.

Can beginners use the Landmine Single-Arm Press?

Yes. It is often beginner-friendly because the fixed arc can make pressing mechanics easier to learn than a fully vertical overhead press.

Recommended Equipment

Landmine Attachment for Barbell — the key tool for creating a smooth 360° landmine pressing setup
Barbell Collars — helps keep plates secure during pressing and setup changes
Fractional Weight Plates — useful for making small progressive overload jumps without disrupting technique
Resistance Bands Set — excellent for shoulder warm-ups, pull-aparts, and activation work before pressing
Foam Exercise / Knee Pad — helpful for half-kneeling landmine press variations and more comfortable floor contact

Tip: The best first purchase for this exercise is a solid landmine attachment. After that, small plates, collars, and warm-up tools make progression and setup easier.
