How to do the Single-Arm Linear Jammer

Steps

1. Position a bar into a landmine or securely anchor it in a corner. Load the bar to an appropriate weight.
2. 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.
3. Perform the movement by extending the elbow, pressing the weight up. Move explosively, extending the hips and knees fully to produce maximal force.
4. Return to the starting position.

Tracking it in OneRep

Add the single-arm linear jammer to a routine and your previous weight and reps sit beside every set, so the decision to add load is made by what is already on the screen rather than by memory. Exercise history and volume trends are one tap away, and logging works offline for the gyms where signal does not reach.

Because OneRep tracks food on the same timeline, a stall on this lift can be read against what you were actually eating that month — which is the difference between a programming problem and an eating one. More on that in tracking progressive overload without a spreadsheet.

Where the instructions come from

The steps above come from free-exercise-db, a public-domain exercise dataset. They are general guidance, not coaching for your body: if a movement hurts, stop and get someone qualified to look at it.
