How to Perform the Barbell Skullcrusher
- Lie flat on a bench and grip a barbell with a close overhand grip, about 8-12 inches apart.
- Press the barbell up so it is directly above your chin or forehead with arms fully extended.
- Keeping your upper arms stationary and perpendicular to the floor, slowly bend your elbows to lower the barbell toward your forehead.
- Lower the bar until it is just above your forehead or slightly behind your head for a greater stretch.
- Pause briefly at the bottom, then extend your elbows to press the bar back to the starting position.
- Squeeze your triceps at the top and repeat, keeping your elbows from flaring out throughout the set.
Common Mistakes to Avoid
Flaring the elbows wide apart
Keep your elbows shoulder-width apart and pointing toward the ceiling to isolate the triceps.
Moving the upper arms back and forth
Lock your upper arms in position; only your forearms should move to ensure the triceps are doing all the work.
Lowering the bar too quickly without control
Use a slow 2-3 second eccentric to maintain tension and protect the elbow joints from excessive stress.
Muscles Worked
Benefits
- ✓Effectively isolates all three heads of the triceps.
- ✓Allows for progressive overload with a barbell for consistent strength gains.
- ✓Builds the elbow extension strength needed for pressing movements.
Pro Tips
- ●Use an EZ bar if the straight barbell causes wrist strain.
- ●Lower the bar slightly behind your head rather than to the forehead for a deeper tricep stretch.
- ●Keep your feet flat on the floor to maintain stability on the bench.
