How to do the landmine linear jammer

  1. Position a bar into landmine or, lacking one, securely anchor it in a corner. Load the bar to an appropriate weight and position the handle attachment on the bar.
  2. Raise the bar from the floor, taking the handles to your shoulders. This will be your starting position.
  3. In an athletic stance, squat by flexing your hips and setting your hips back, keeping your arms flexed.
  4. Reverse the motion by powerfully extending through the hips, knees, and ankles, while also extending the elbows to straighten the arms. This movement should be done explosively, coming out of the squat to full extension as powerfully as possible.
  5. Return to the starting position.

Muscles worked

The prime movers are the deltoids, which raise and rotate the upper arm at the shoulder joint.

Because more than one joint is moving, the work does not stay in one place: the abdominals brace the trunk so force can pass between the hips and the shoulders; the calves control the ankle and hold the heel position; the chest adds pushing force at the shoulder.

The hamstrings, quadriceps and triceps take a share of the work as well.

How this movement works

The working muscles shorten as they drive the load away from you, and more than one joint changes angle to do it. Load spreads down a chain instead of sitting on one muscle, which is why a compound push handles more weight than any single-joint alternative — and why joint position, not the muscle, is usually what fails first.

It is filed under strength: produce force against resistance for a countable number of repetitions, and progress the resistance over time.

What you need

A barbell locks both hands to one bar, so neither side can drift and the load climbs in plate-sized steps. That makes it the simplest way to add weight and the least forgiving thing to bail out of.

Difficulty

Listed at intermediate level. It assumes you already own the underlying pattern and can hold position under load — if the position breaks before the target muscle tires, drop back to a beginner variation until it does not.
