Lying Triceps Extension (skull crusher)

Exercise: Lying Triceps Extension (skull crusher)

Muscles Exercised: Triceps

Description: When trying this exercise for the first time, choose a very light weight, or just use the bar for practice. This exercise completely isolates the triceps and allows you to maximally stimulate this muscle group.

Use the “ez curl” or cambered bar for this exercise. Sit down at the end of a bench with your spotter at the head side of the bench. You can either lay down and lift the bar into the starting position on the way down, or have your spotter pass you the bar once you are in position.

Grip the bar with a close, underhand grip (although you can alternate your grip - palms down - to get a different effect). Keep your arms (and elbows) less than shoulder width apart. Extend your arms until they are nearly fully extended and then lower the bar down until it's almost touching your forehead. Repeat for the desired amount of reps until complete.
