- Isolation

Setup
- Set an adjustable bench to a 30 to 45-degree incline.
- Sit back with your head and spine supported and feet planted firmly on the ground for stability.
- Hold a dumbbell in each hand with a neutral grip (palms facing each other).
- Extend your arms straight up so they are perpendicular to the floor or angled slightly back toward your head.
How to do it
- Inhale and slowly lower the dumbbells by bending only at the elbows until the weights are beside your ears.
- Keep your upper arms fixed and elbows pointing forward throughout the descent.
- Exhale and contract your triceps to extend your arms back to the starting position.
- Maintain a controlled tempo, focusing on a 3-second lowering phase and a 1-second squeeze at the top.
Form checklist
- Keep elbows tucked in and avoid letting them flare out to the sides.
- Ensure the upper arm remains stationary; only the forearm should move.
- Keep your lower back pressed against the bench to prevent arching.
- Maintain a neutral wrist position throughout the entire set.
Pro tips
- Angle your upper arms slightly back toward your head (about 15 degrees) rather than perfectly vertical to keep constant tension on the triceps at the top of the rep.
- Focus on the 'stretch' at the bottom of the movement to maximize hypertrophy in the long head of the triceps.
Make it harder
- Incorporate a 2-second pause at the bottom of each rep to eliminate momentum and increase time under tension in the stretched position.
- Perform the exercise unilaterally (one arm at a time) to identify and correct strength imbalances.
