How to Do Barbell Lying Triceps Extension Skull Crusher
- 1Setup
Lie supine on a flat bench with your feet flat on the floor, holding a barbell with an overhand grip, hands shoulder-width apart.
- 2Setup
Extend your arms straight up, positioning the barbell directly over your upper chest, ensuring your elbows are slightly bent to avoid locking out.
- 3
Inhale and slowly lower the barbell by bending only your elbows, allowing the bar to descend towards your forehead or just behind your head. Keep your upper arms stationary throughout the movement.
- 4
Feel a stretch in your triceps, then powerfully exhale as you extend your elbows, pushing the barbell back to the starting position using only your triceps.
- 5
Maintain control at the top, avoiding locking your elbows, and prepare for the next repetition.
Tips
- Keep your elbows tucked in and pointing forward throughout the exercise. Flaring them out reduces triceps activation and can put undue strain on the shoulder joint.
- Control the eccentric (lowering) phase by slowly lowering the weight. This increases time under tension, enhancing muscle growth and improving control.
- Consider using an EZ curl bar instead of a straight barbell if you experience wrist discomfort, as its angled grips can provide a more natural hand position.
- Always prioritize form over weight; it's better to use a lighter weight with perfect execution to maximize triceps engagement and minimize injury risk.
Common Mistakes
- ×Many people flare their elbows out, reducing triceps engagement; keep your elbows tucked in and pointed forward to maximize triceps activation.
- ×Lifting a weight that is too heavy often leads to using momentum or involving the shoulders; reduce the weight to focus on strict triceps isolation and controlled movement.
- ×Lowering the bar excessively behind the head can strain the shoulder joint; aim to bring the bar to your forehead or just slightly behind it while maintaining stable upper arms.
