Description
Skull Crusher (Skull Crusher) is a classic triceps isolation exercise performed lying on a flat bench using a barbell or EZ bar. This exercise strongly targets all three heads of the triceps muscle but places significant tension especially on the long head. It is considered one of the most effective triceps exercises for increasing arm mass and strength. Its name comes from the possibility of the bar coming toward the forehead if control is lost, so performing it with control is extremely important. It is commonly used by both beginners and advanced athletes. The EZ bar version is generally preferred because it places less stress on the wrists.
Skull Crusher How-To Guide
- 1
Lie on your back on a flat bench, extend your arms straight up holding an EZ bar or straight bar with a shoulder-width grip
- 2
Keeping your upper arms stationary, slowly lower the bar to just above your forehead or behind your head
- 3
Bring the bar to the bottom position in a controlled manner without flaring your elbows outward
- 4
Push the bar back to the starting position powerfully by contracting your triceps
- 5
Move slowly during the negative phase and keep your elbows fixed at shoulder width
- 6
Always have a spotter for safety when using heavy weights
Key Points
- ✓Lie on your back, use a barbell or EZ bar, maintain shoulder-width grip
- ✓Lower the bar in a controlled manner to the forehead or above the head
- ✓Elbows should be stationary and slightly turned inward, not flared outward
- ✓Upper arms should be perpendicular to the floor or slightly tilted back
- ✓Fully contract and lock out the triceps when pushing the bar up
Common Mistakes
- ✗Flaring elbows too wide - places stress on the shoulder and elbow joints
- ✗Lowering the bar too quickly with risk of hitting the head or face - control is essential
- ✗Using too heavy weight and moving the elbows - risk of injury
- ✗Moving the upper arms - shoulders engage, triceps isolation is compromised
Breathing
Inhale as you lower the bar, exhale as you lift it up. You can hold your breath briefly during the most difficult part of the movement.
