Barbell Reverse Grip Skullcrusher

The reverse grip skullcrusher flips the hands underhand for the lying triceps extension, which changes the angle at the elbow and shifts more emphasis onto the long head of the triceps along with the forearms. It's a less common grip that takes some adjustment before it feels stable overhead. Keep the elbows steady and start with lighter weight than your standard skullcrusher until the groove feels secure.

How to Do the Barbell Reverse Grip Skullcrusher

1. Lie back flat on a bench, feet planted on the floor and your head near the end of the bench.
2. Grip the barbell with a reverse hold, palms turned toward your face, hands set shoulder-width apart.
3. Press the bar straight up above your chest, keeping your elbows tucked in and your wrists locked straight.
4. Bend your elbows to lower the bar slowly toward your forehead, keeping your upper arms fixed in place.
5. Hold briefly at the bottom, then straighten your arms to bring the bar back up.
6. Repeat for your target rep goal, keeping your core engaged and avoiding any reliance on momentum.

Technique & Form Tips

Focus on controlled elbow extension while keeping your upper arms fixed in the position required by your specific variation, such as a pushdown or overhead extension. Manage your range of motion based on your own comfort during both flexion and extension.

Common Mistakes to Avoid

• Elbow migration: Keep the upper arm stationary to prevent the movement from turning into a different exercise.
• Inconsistent elbow tracking: Follow the intended path for your elbows to ensure they do not excessively flare outward.
• Forcing the end position: Straighten and bend the elbow through a controlled, comfortable range without snapping into the end position.

How to Breathe During This Exercise

Breathe continuously, matching your inhale and exhale to the pace of your repetitions.

Comfort and Control

Choose a load and range you can control. Stop if the movement causes pain. If discomfort persists, stop and ask a qualified professional about an appropriate exercise and range.
