Setup
- Stand with your feet shoulder-width apart and a slight bend in your knees for stability.
- Grip a single dumbbell with both hands, forming a diamond shape with your palms against the underside of the top weight plate.
- Lift the dumbbell directly overhead until your arms are fully extended and your biceps are near your ears.
How to do it
- Inhale as you slowly lower the dumbbell behind your head by bending only at the elbows, keeping your upper arms stationary and vertical.
- Lower the weight until your forearms are at least parallel to the floor or you feel a deep stretch in the triceps.
- Exhale as you use your triceps to press the weight back to the starting position using a controlled 2-0-2 tempo.
Form checklist
- Keep your elbows tucked in toward your head rather than flaring them out to the sides.
- Engage your core and glutes to prevent your lower back from arching as the weight moves behind you.
- Ensure only your forearms are moving; your upper arms should remain perpendicular to the floor throughout the set.
- Maintain a neutral neck position, looking straight ahead rather than down at the floor.
Pro tips
- Focus on the deep stretch at the bottom of the movement to maximize recruitment of the triceps' long head.
- Avoid a hard lockout at the top of the rep to keep constant tension on the muscle fibers.
Make it harder
- Perform the exercise unilaterally (one arm at a time) to increase core stability demands and address strength imbalances.
- Add a 2-second pause at the bottom of each repetition to eliminate momentum and increase time under tension.
