- Intermediate
- Isolation
- Rep-based
- Chest

Setup
- Lie flat on a bench with your feet firmly planted on the floor for stability.
- Hold a dumbbell in each hand directly over your chest with your arms fully extended.
- Rotate your wrists so your palms are facing toward your feet in a pronated grip.
- Position your upper arms so they are vertical or slightly tilted back toward your head to maintain constant tension.
How to do it
- Inhale and slowly lower the dumbbells by bending only at the elbows, bringing the weights down toward the sides of your forehead.
- Keep your upper arms stationary and tucked in throughout the entire descent.
- Exhale as you use your triceps to extend your arms back to the starting position, focusing on a strong contraction at the top.
- Maintain a controlled 3-second eccentric (lowering) phase and a 1-second concentric (lifting) phase.
Form checklist
- Keep your elbows tucked in and avoid letting them flare out to the sides.
- Ensure the movement occurs only at the elbow joint; the shoulders should remain locked in place.
- Keep your lower back pressed against the bench to avoid arching.
- Maintain a firm, pronated grip without letting the wrists collapse.
Pro tips
- Focus on the mind-muscle connection by imagining you are pushing the weight away using only the back of your arms.
- For maximum long-head activation, lower the dumbbells slightly past your ears to increase the stretch before extending.
Make it harder
- Pause for two seconds at the bottom of the movement to eliminate momentum and increase time under tension.
- Perform the exercise on a slight decline bench to further increase the range of motion and triceps recruitment.
