How to Perform Skull Crushers
Equipment Setup
You can perform skull crushers using dumbbells or a barbell, on either a flat or incline bench. If using a barbell, load it with a weight that suits your fitness level.
Starting Position
- Flat Bench – Lie down with your back pressed firmly against the bench.
- Incline Bench – Adjust the angle to a comfortable position.
- Foot Placement – Keep your knees bent and feet flat on the floor.
- Grip –
- For a barbell or EZ curl bar, use an overhand grip with hands slightly wider than shoulder-width.
- If using dumbbells, hold them with palms facing inward.
Executing the Movement
- Fully extend your arms, holding the weight above your chest.
- Slowly lower the bar toward your forehead, keeping your elbows close to your head. Avoid touching your forehead.
- Pause briefly at the lowest point.
- Raise the weight back to the starting position, ensuring your elbows remain steady throughout the movement.
Reps and Sets
- Perform 8–12 reps per set.
- Take short rests between sets.
- Complete the desired number of sets based on your workout plan.
