JM Press

How to perform it

1. 1Preparation and positioning. Use a stable bench, set rack hooks and safety arms, and use a competent spotter for heavy or near-failure barbell work. Secure plates with collars.
2. 2Starting position. Set stable foot and upper-back contact, take the prescribed grip, unrack to straight arms, and hold the load above the shoulder line.
3. 3Eccentric / dip phase. Lower the load under control to the fixed chest, upper-arm, or hover marker while the forearms remain well aligned.
4. 4Bottom / transition position. Reach the same controlled pause, floor contact, or hover distance without bounce; keep the wrists and shoulders centered.
5. 5Concentric phase / lockout. Press the load to stable elbow extension over the shoulder line without bouncing or losing upper-back contact. For the JM press, keep the path between a close-grip press and elbow extension; do not turn it into a free-falling skull crusher.
6. 6Breathing and bracing. Brace before the loaded phase, maintain pressure through the sticking region, and exhale/reset only when the load is stable. Avoid prolonged breath-holding across repetitions.
7. 7Valid rep. A rep uses the same start, depth, pause/hover standard, and lockout with no bounce, spotter contact, unplanned leg drive, or change in load path.

Common mistakes

• Losing wrist–forearm alignment

  Fix: Stack the wrist over the forearm and adjust grip, handle, or range before adding load.

• Elbows escaping the intended path

  Fix: Use a repeatable elbow angle that keeps forearms supportive and shoulders controlled.

• Creating range with the lower back

  Fix: Keep ribcage over pelvis and stop at the shoulder range you can own.

• Bouncing or dropping the bottom

  Fix: Lower under control to a fixed marker and reverse without rebound.

Safety

• For heavy barbell work, use correctly set safeties and/or a competent spotter and collars; do not rely on a spotter to rescue a technically uncontrolled repetition.
• Choose a load, range, and setup that permit a controlled return or exit; stop the set rather than compensating through sharp or progressively worsening symptoms.

Progressions & alternatives

• regressionCable Triceps Pushdown— Reduce strength, balance, or coordination demand while rehearsing the key pattern before returning to JM Press.
• progressionOverhead Triceps Extension— Increase load, range, instability, or skill demand after JM Press is repeatable through the planned volume with reserve and no technique drift.
• alternativeClose-grip Press— Train a similar primary pattern with a different stability, equipment, or joint-loading profile when JM Press is impractical or poorly tolerated.
