Sit on the end of a flat bench with a barbell on your thighs.

Grip the barbell with an underhand grip (Palms facing up) with your hands about shoulder width apart.

Bring the bar up to your chest and lay down on your back.

Extend your arms straight up above your chest.

Keeping your elbows fixed in place and not pointing out, slowly lower the bar until it is about an inch from your forehead (hence the name skullcrusher!).

Pause, and then slowly extend your arms back to the starting position.

Do not lock your elbows out, and then repeat for desired reps.

Exercise Tips:

This exercise is best when using an EZ bar, because it's much easier onthe wrists when using a reverse grip.

Keep your elbows in throughout the set and don't allow them to move forward or back as your raise the weight.

Keep your rep timing slow and control the weight on the way down.
