Barbell JM-Bench Press
- Intermediate
- Compound
- Rep-based
- Chest
- Upper arms
- Waist
The JM Press is a high-performance hybrid between a close-grip bench press and a triceps extension, specifically designed to build massive triceps strength and lockout power. It utilizes the pectorals and deltoids as stabilizers while placing maximum mechanical tension on the triceps through a unique range of motion.

Setup
- Lie flat on a bench with your eyes directly under the barbell.
- Grip the bar with a shoulder-width or slightly narrower grip, ensuring your wrists are stacked over your forearms.
- Unrack the bar and hold it directly over your upper chest with your shoulder blades retracted and feet driven into the floor.
- Position your elbows so they are tucked at a 45-degree angle relative to your torso.
How to do it
- Inhale and lower the bar in a straight line toward your chin or upper chest by simultaneously bending the elbows and allowing them to travel slightly forward toward your feet.
- Lower the weight until your forearms make contact with your biceps, ensuring the bar stays over your face/neck area rather than your mid-chest.
- Exhale and drive the bar back to the starting position by forcefully extending your elbows and pushing through the triceps.
- Maintain a controlled 3-second eccentric phase and a powerful 1-second concentric phase.
Form checklist
- Keep the bar path vertical over the upper chest and neck area.
- Ensure your elbows stay tucked and do not flare out to the sides.
- Keep your wrists neutral and rigid to prevent strain.
- Do not bounce the bar off your chest; maintain total control at the bottom of the rep.
Pro tips
- Think of the movement as a 'folding' action where the bar moves toward your face while the elbows move toward your hips.
- Focus on the mind-muscle connection by 'squeezing' the triceps to initiate the upward drive from the bottom position.
Make it harder
- Add resistance bands to the bar to create accommodating resistance, increasing tension at the lockout.
- Implement a 2-second pause at the bottom of each rep to eliminate elastic recoil and maximize muscle fiber recruitment.
