Setup
- Set an incline bench to an angle between 30 and 45 degrees.
- Sit firmly against the backrest with your feet flat on the floor for stability.
- Grasp a weight plate on opposite sides (3 o'clock and 9 o'clock positions) with a neutral grip.
- Extend your arms straight up so the plate is directly above your chest/head, keeping your elbows tucked.
How to do it
- Inhale and slowly lower the plate behind your head by bending only at the elbows, keeping your upper arms stationary and vertical.
- Lower the weight until you feel a full stretch in your triceps, ensuring the plate does not hit the bench.
- Exhale as you use your triceps to extend your arms back to the starting position, focusing on a powerful contraction.
- Maintain a controlled tempo, taking 2 seconds to lower the weight and 1-2 seconds to press it back up.
Form checklist
- Keep your elbows pointing forward and tucked in; do not let them flare out to the sides.
- Ensure only your forearms move; your upper arms should remain locked in place throughout the set.
- Keep your lower back pressed firmly against the bench to prevent rib flare or spinal arching.
- Avoid using momentum or 'swinging' the plate from the shoulders.
Pro tips
- Focus on the mind-muscle connection by imagining you are trying to pull the plate apart as you extend to increase lateral head engagement.
- Pause for one second at the bottom of the rep to maximize the stretch on the long head of the triceps.
- Keep a slight bend in the elbows at the top of the movement to maintain constant tension on the muscle.
Make it harder
- Slow down the eccentric (lowering) phase to 4 seconds to increase time under tension.
- Perform '1.5 reps' by lowering the plate fully, coming halfway up, lowering again, and then extending fully to the top.
