Lying tricep extensions (Barbell)

COURTESY OF GLOBAL FITNESS

Major muscles used

• Triceps

Performing lying tricep extensions (aka Skull crushers)

• Lie on your back on a bench, holding a barbell above your face with a narrow grip, hands 6-8 inches apart, with palms facing up.
• Your feet should be together on the bench and legs slightly apart.
• Keeping your upper arms straight (from shoulders to elbows) and your elbows at a "fixed-point", slowly lower the weight down until it barely reaches your forehead.
• Raise the weight to the starting position, keeping your upper arms and elbows in the same position.

Be careful

• Don't sway your arms through the motion. Concentrate on only using your triceps.
• Don't let your elbows wander outward from your body.
• Don't cut the movement short. Be sure to raise the barbell until your arms are fully extended and lower it until it barely touches your forehead.
