Landmine Linear Jammer
The landmine linear jammer has you standing in an athletic stance, holding the loaded end of a barbell anchored in a landmine sleeve at chest height, then explosively extending your hips, knees, and arms together to drive the bar forward and slightly upward. It's less a shoulder press than a full-body extension that happens to finish through the shoulders, closer in feel to a punch or a shot-put throw than a slow overhead lift. The angled bar path takes some strain off the shoulder joint compared to a straight vertical press, which is part of why it shows up in athletic and combine-style training.
Why it works
Because the bar pivots from a fixed point on the floor, its path arcs up and away from your chest rather than straight overhead, letting your legs and hips contribute real drive to the press instead of leaving your shoulders to do all the work alone. Your quads and hamstrings extend first, your core transmits that force up through your trunk without letting your lower back arch, and your shoulders, chest, and triceps finish the movement by locking the bar out at the end of its arc. That hip-to-hand sequencing, extend the legs first, then the arms, is the same pattern behind throwing, punching, and jumping, which is why the jammer builds explosive pressing power rather than just shoulder size.
Set up
- Anchor one end of a barbell in a landmine attachment or a sturdy corner.
- Stand in a staggered or athletic stance facing the anchor, holding the free end of the bar at chest height with both hands, elbows bent and tucked.
- Brace your core and set your feet before the first rep.
How to do it
- Drive through your legs first, extending your hips and knees explosively.
- Let that leg drive transfer up through your core into your arms.
- Press the bar forward and slightly upward, finishing with your arms extended.
- Control the bar back down to your chest rather than letting it drop.
- Reset your stance briefly between reps if power output starts to fade.
Form cues
- Legs drive first; the arms finish what the hips start.
- Core stays braced so force travels up, not into an arched back.
- Bar path angles up and away, not straight overhead.
- Control the bar back to your chest every rep.
Breathing: Exhale sharply as you drive the bar forward, inhale as you bring it back to your chest.
Common mistakes
Pressing with the arms alone and skipping the leg drive.
Fix: Pause and feel your hips and knees extend first before your arms move at all.
Arching the lower back to help drive the bar.
Fix: Keep your ribs stacked over your hips and brace your core hard before each rep; a braced trunk transmits leg drive without needing to arch.
Letting the bar crash back to the chest between reps.
Fix: Catch and control the bar's return with your arms and shoulders every time, even when you're chasing more reps.
Loading the bar heavier than your form can control.
Fix: Drop the weight until every rep looks the same from the first to the last; this movement trains power output, not a one-rep max.
How to program it
- Three or four sets of 5 to 8 explosive reps per side is typical, since the point is producing power on every rep, not grinding out volume.
- Loaded jammer work is demanding on the whole body at once, so once a week is usually enough when it's the main power movement in a session.
- Program it early in a workout, right after your warm-up, while your nervous system is fresh enough to move the bar with real speed.
- If you train both sides, split your reps evenly between a staggered stance leading with each leg.
Safety notes
- Keep the load light enough that your form stays identical on the last rep as the first; a jammer that turns into a grinding press has stopped training power and started risking your shoulders.
- Make sure the landmine sleeve or corner anchor is genuinely stable and the barbell sleeve is secure before adding weight.

Frequently asked questions
What muscles does the landmine linear jammer work?
Its primary target is the shoulders, with real contribution from your chest, triceps, quads, hamstrings, calves, and abdominals as the whole body extends together.
Is the landmine linear jammer the same as a shoulder press?
Not quite. A shoulder press moves slowly and straight up under control; the jammer is an explosive, full-body extension that happens to finish through the shoulders, closer to a punch or a shot-put motion.
How many reps should I do for landmine jammers?
Five to eight explosive reps per set, for 3 or 4 sets, keeps the focus on producing power rather than grinding through fatigue.
What can I use instead of a landmine attachment for jammers?
A cable shoulder press trains a similar pressing pattern for the shoulders, though without the same hip-driven power component.
