Intro: Lying tricep extensions are a solid exercise to include in any bodybuilding or fitness routine. They are sometimes called skull crushers. They will hit the long head of your tricep that does not get much work in other chest and tricep exercises. You will need a flat bench and a curl bar to perform them. The E-Z curl bar is recommended. Form is very important here and should not be neglected. Do not bring the weight to your forehead as many people do.

How it is performed: Approach the flat bench with a loaded E-Z curl bar. Place the bar on the ground in front of the bench and lie on your back. Position yourself so that your head is hanging off the side of the bench. In this position, reach for the curl bar and grip it with a narrow grip. The starting position is having your arms extended with the E-Z curl bar over your upper chest area.

Lower the bar by bending your elbows. Make sure you keep them in throughout the duration of the lift. Allow the curl bar to go past your head and make the necessary adjustments to do this with your elbows. Go down until you feel a stretch in your triceps. Rotate your elbows again to move the weight back up into the starting position.

When you are finished, lower the weight back behind your head so you can drop it on the floor or have a spotter take it for you. It is very important to maintain proper form. Flaring your elbows or using to much weight could potential cause an injury.
