Incline Skull Crusher
How to Do an Incline Skull Crusher
Set an adjustable bench to approximately 30–45 degrees.
Lie back and hold a barbell with a comfortable grip slightly narrower than shoulder width.
Press the bar above the upper chest with elbows extended.
Keep the upper arms relatively stable as you bend the elbows.
Lower the bar toward the forehead or slightly behind the head depending on comfort.
Stop at a controlled depth without forcing the shoulders or elbows.
Extend the elbows and return the bar to the start.
Form Check & Technique
DO THIS (Technique Tips)
- Start with a 30–45 degree bench angle.
- Use conservative loads.
- Keep the bar path controlled near the head.
- Use an EZ bar if wrist comfort is better.
- Do not assume a steeper incline is automatically better.
AVOID THIS (Common Mistakes)
- Setting the bench excessively upright — Fix: Start around 30–45 degrees.
- Using too much weight — Fix: Reduce load until the path is controlled.
- Letting elbows flare dramatically — Fix: Keep them relatively stable.
- Dropping the bar quickly — Fix: Use a deliberate eccentric.
- Turning it into an incline press — Fix: Keep most motion at the elbows.
- Using an uncomfortable straight-bar grip — Fix: Try an EZ bar.
About Incline Skull Crusher
The incline skull crusher is a lying barbell triceps extension performed on an incline bench, commonly around 30–45 degrees. The incline changes the upper-arm and shoulder position compared with a flat skull crusher, creating a different line of movement while the triceps extend the elbows. Current research supports the importance of shoulder position in triceps training, but it does not directly prove that incline skull crushers are superior to flat skull crushers.
Incline Skull Crusher Muscles Worked
The triceps perform elbow extension.
- The incline changes shoulder and upper-arm position compared with a flat skull crusher, while forearms and shoulders stabilize the bar.

What Bench Angle Should You Use?
A 30–45 degree incline is a practical starting range. Higher inclines move the shoulder position closer to a fully overhead extension.
Incline vs Flat Skull Crusher
The incline changes torso and upper-arm angle relative to gravity. Both train elbow extension, but the shoulder position and bar path feel different.
Incline Skull Crusher vs Overhead Extension
The incline position sits between flat lying and fully overhead shoulder positions.
Does Incline Automatically Build More Triceps?
Not necessarily. Shoulder position can influence triceps training, but direct research has not established incline skull crushers as superior to flat skull crushers.
