Setup
- Sit on the end of a flat bench with your feet planted firmly on the floor for stability.
- Grasp the barbell with an overhand (pronated) grip, with hands spaced about 6-8 inches apart.
- Press the barbell directly overhead until your arms are fully extended and your biceps are near your ears.
- Engage your core and pull your ribcage down to prevent your lower back from arching.
How to do it
- Inhale and slowly lower the barbell behind your head by bending only at the elbows, keeping your upper arms vertical and stationary.
- Lower the weight until your forearms are at least parallel to the floor and you feel a deep stretch in the triceps.
- Exhale and drive the barbell back to the starting position by extending your elbows, focusing on the triceps contraction.
- Maintain a controlled tempo, taking 2-3 seconds to lower the weight and 1 second to press it back up.
Form checklist
- Keep your elbows tucked in and pointing forward rather than flaring out to the sides.
- Ensure only the forearms move; the upper arms should remain perpendicular to the floor throughout.
- Maintain a neutral spine and avoid leaning forward or excessively arching the back.
- Avoid locking out the elbows aggressively at the top to maintain tension on the muscle.
Pro tips
- Focus on the 'stretch' at the bottom of the movement, as this is where the long head of the triceps is most active.
- If using a straight barbell causes wrist discomfort, try using an EZ-bar to allow for a more natural semi-supinated grip.
- Imagine you are trying to touch the barbell to the middle of your upper back while keeping your elbows glued in place.
Make it harder
- Add a 2-second pause at the bottom of each repetition to increase time under tension in the stretched position.
- Perform the exercise on a bench with a short back support to allow for heavier loading while maintaining strict torso positioning.
