Setup
- Place a flat bench in front of a low cable pulley machine.
- Attach a straight bar or EZ-curl bar to the low pulley.
- Lie face-up on the bench with your head positioned closest to the weight stack.
- Reach back to grasp the bar with an overhand, shoulder-width grip and bring it over your chest.
How to do it
- Start with your arms extended, but angled slightly back toward the pulley (about 15-30 degrees) to keep tension on the triceps.
- Inhale and slowly lower the bar toward your forehead or just behind your head by bending only at the elbows.
- Exhale and drive the bar back to the starting angled position by fully extending your elbows.
- Maintain a controlled tempo, taking 2 seconds to lower the weight and 2 seconds to extend.
Form checklist
- Keep your elbows tucked in and pointing forward; do not let them flare out to the sides.
- Ensure your upper arms remain completely stationary throughout the set.
- Keep your lower back and hips pressed firmly against the bench.
- Avoid using your shoulders or momentum to 'swing' the weight up.
Pro tips
- Keep the upper arms angled back toward the pulley even at the top of the movement to prevent the triceps from 'resting' at full extension.
- Focus on a deep stretch at the bottom of the movement to maximize recruitment of the triceps long head.
- Imagine your elbows are pinned to an invisible board to ensure the movement remains strictly at the elbow joint.
Make it harder
- Swap the bar for a rope attachment to allow for a neutral grip and a greater range of motion at the bottom.
- Add a 2-second isometric hold at the point of maximum stretch (bottom) of each rep.
