Setup
- Lie flat on a bench with your feet firmly planted on the floor for stability.
- Grasp the Olympic barbell with an overhand grip, hands spaced shoulder-width apart.
- Extend your arms fully to hold the bar directly over your upper chest.
- Retract your shoulder blades into the bench to create a stable base for the lift.
How to do it
- Inhale and slowly lower the bar by bending only at the elbows, bringing the bar toward your forehead or just past the top of your head.
- Keep your upper arms stationary and perpendicular to the floor throughout the descent.
- Exhale and use your triceps to extend your arms back to the starting position, focusing on a strong contraction at the top.
- Maintain a controlled 3-second tempo on the descent and a powerful 1-second tempo on the ascent.
Form checklist
- Keep your elbows tucked in and pointing forward; do not let them flare out to the sides.
- Ensure the movement occurs only at the elbow joint; keep the shoulders and upper arms still.
- Maintain a neutral spine and avoid arching your lower back off the bench.
- Control the weight throughout the entire range of motion to avoid hitting your head.
Pro tips
- Angle your upper arms slightly back toward your head (about 15 degrees) to maintain constant tension on the triceps at the top of the movement.
- Focus on the mind-muscle connection by imagining your triceps pulling your forearms back into the straight position.
Make it harder
- Perform the exercise on a slight decline bench to increase the stretch and range of motion for the long head.
- Add a 2-second pause at the bottom of the rep to eliminate momentum and increase time under tension.
