- Keeping your upper arms stationary, slowly bend your elbows to lower the dumbbells toward your temples.
- Stop just before the dumbbells reach your forehead, ensuring control at all times.
- Press the dumbbells back up by extending your elbows to return to the starting position.
Technical Tips
- Keep your elbows fixed and close to your head throughout the movement.
- Avoid letting your upper arms drift backward during the eccentric phase.
- Use a neutral grip to reduce wrist strain and improve triceps engagement.
- Perform the movement slowly and under control to maximize muscle tension.
Breathing Tips
- Inhale as you lower the dumbbells toward your head.
- Exhale as you extend your arms and return to the starting position.
Medical restrictions
- Elbow tendonitis or joint pain

- Wrist injuries or limited wrist mobility
The Dumbbell Skullcrusher is an effective isolation exercise designed to build and strengthen the triceps. Performed lying on a musculation bench, this movement targets the muscles through elbow extension, promoting muscle hypertrophy and definition in the upper arms. By using individual dumbbells, the exercise allows for a more natural wrist position and better range of motion compared to barbell variations, which can enhance muscle activation and joint comfort. It also helps correct muscular imbalances between the arms by engaging both limbs independently. Ideal for intermediate lifters, the Dumbbell Skullcrusher is a staple in bodybuilding and fitness routines aimed at increasing arm size and pushing strength. Its simplicity and minimal equipment requirements make it accessible for home and gym settings alike, while its focused execution delivers targeted results. Incorporating this movement into your training program can significantly improve triceps development and contribute to overall upper body performance.
How do I avoid hitting my forehead during dumbbell skullcrushers?
To avoid hitting your forehead during dumbbell skullcrushers, keep your elbows steady and lower the dumbbells slightly behind your head instead of directly toward your face. This ensures a safe range of motion and protects your skull.
Can I use heavy weights for dumbbell skullcrushers?
Yes, you can use heavy weights for dumbbell skullcrushers, but it's crucial to prioritize form. Using moderate weights with controlled movement often yields better results and reduces the risk of elbow or shoulder strain.
Are dumbbell skullcrushers better than barbell skullcrushers?
Dumbbell skullcrushers offer a greater range of motion and allow for more natural wrist positioning, which can reduce joint stress and improve triceps isolation compared to barbell skullcrushers.
What bench angle should I use for dumbbell skullcrushers?
A flat bench is most commonly used for dumbbell skullcrushers, providing optimal triceps engagement. However, a slight incline can also be used to vary the stimulus and target the long head of the triceps more intensely.
Can beginners perform dumbbell skullcrushers safely?
Beginners can perform dumbbell skullcrushers safely by starting with light weights and focusing on proper form. Controlled movement and supervision are key to preventing injury and ensuring effectiveness.
