How to perform Single-Arm Linear Jammer
- Position a bar into a landmine or securely anchor it in a corner. Load the bar to an appropriate weight.
- Raise the bar from the floor, taking it to your shoulders with one or both hands. Adopt a wide stance. This will be your starting position.
- Perform the movement by extending the elbow, pressing the weight up. Move explosively, extending the hips and knees fully to produce maximal force.
- Return to the starting position.
Muscles worked
- Shoulders (primary): raises and rotates the arms and drives everything overhead.
- Chest (secondary): pushes the arms forward and across the body — your horizontal pressing power.
- Triceps (secondary): straightens the elbow to lock out every press and pushdown.
Sets & reps by goal
| Goal | Sets × reps | Load | Rest |
|---|---|---|---|
| Strength | 3–5 × 3–5 | Heavy (~85%+) | 2–3 min |
| Hypertrophy | 3–4 × 8–12 | Moderate (~65–75%) | 60–90 s |
| Endurance | 2–3 × 15–20 | Lighter (~50–60%) | 30–45 s |
Pick the row that matches your goal. If you're newer, anchor in the hypertrophy range while you groove the form.
Form tips
- Keep the ribs down and the glutes tight so the lower back doesn't arch to 'help' the weight up.
- Keep the bar path close and stacked over your mid-foot; letting it drift forward wastes force and loads the lower back.
- Treat every rep the same — a repeatable setup and bar path is what lets you add weight safely over time.
- Stop a rep or two short of failure on most sets to keep form clean and recover faster.
Common mistakes
- Pressing with the lower back arched instead of a braced, stacked torso.
- Loading the bar heavier than your form allows and turning strict reps into a whole-body heave.
- Chasing weight jumps before the current load feels solid on every rep.
