Dumbbell Skull Crushers
Dumbbell skull crushers are an effective exercise for strengthening your triceps. This exercise not only helps build muscle mass but also improves the stability of your elbows and shoulders.
Execution
-
1
Lie on a flat bench with a dumbbell in each hand. Hold the dumbbells with your arms extended above your chest.
-
2
Inhale and slowly bend your elbows to lower the dumbbells. The weights should come down on either side of your head, almost as if you were putting on a helmet.
-
3
Keep your upper arms still throughout the exercise and move only your forearms.
-
4
Press the dumbbells back to the starting position by contracting your triceps and exhaling.
Benefits
- Strengthening and enlargement of the triceps.
- Improved elbow and shoulder stability.
- Increased arm strength that is useful for other exercises such as the bench press.
Common Mistakes
- ! Moving the upper arms: Try to keep your upper arms still to ensure maximum isolation of the triceps.
- ! Lowering the weights too quickly: Lower the dumbbells in a controlled manner to prevent injuries and train the muscles effectively.
Main Muscles
The primary focus is on the triceps brachii. The forearms and part of the shoulder muscles are also engaged secondarily.
Possible Alternatives
- Use an EZ bar instead of dumbbells for a different grip and pressure distribution.
- Perform the exercise on an incline or decline bench to emphasize different parts of the triceps.
- Add a pause at the bottom of the movement to increase the intensity.
