Setup
- Lie flat on a bench with your feet firmly planted on the floor for stability.
- Grasp the barbell with an overhand grip, hands spaced roughly 6-8 inches apart (inside shoulder width).
- Extend your arms straight up, then tilt them back slightly toward your head so your upper arms are at a 75-degree angle to the floor.
- Retract your shoulder blades and press them into the bench.
How to do it
- Inhale and slowly lower the bar by bending only at the elbows until it is just above your forehead or slightly behind the top of your head.
- Keep your upper arms stationary and your elbows tucked in throughout the entire descent.
- Exhale and use your triceps to extend your arms back to the starting position, maintaining the slight backward tilt of the upper arms to keep constant tension.
- Follow a controlled tempo, taking 2-3 seconds to lower the weight and 1 second to extend.
Form checklist
- Keep elbows tucked in and pointing forward; do not let them flare out to the sides.
- Ensure the movement occurs exclusively at the elbow joint; keep the shoulders locked in place.
- Maintain a neutral wrist position to avoid unnecessary strain on the forearm and wrist joints.
- Keep your lower back in a natural position, avoiding excessive arching off the bench.
Pro tips
- Lowering the bar slightly behind your head rather than to your forehead increases the stretch on the long head of the triceps.
- Focus on the mind-muscle connection by imagining you are 'unfolding' your arms using only the back of your upper arm.
- Stop just short of a full lockout at the top to maintain continuous tension on the muscle fibers.
Make it harder
- Perform the movement on a decline bench to increase the range of motion and the stretch at the bottom of the rep.
- Incorporate a 'dead stop' at the bottom by resting the bar for one second on the bench behind your head to eliminate momentum.
