The lying tricep extensions exercise is a great way of executing a good muscle building program for your triceps.  This is an exercise that you would like to start off by using small weights and gradually work your way up with experience.

However, if you want your arms to look proportion with one another, then building strong triceps is an essential part of succeeding.  You have to look proportion to look good. 

Here you will find a step by step description on how to properly do this exercise:

• Another name for this exercise is called the skull crushers for a simple reason.
  
• Be sure to never start heavy and start with a light weight.
• Skull crushers can  be performed with dumbbells as well. 
• This exercise may be done easier by using an EZ-curl bar instead of a straight bar or with dumbbells.
  

1. On a flat bench, lie on your back with a barbell or an EZ-Curl bar.
2. Use a close overhand grip and press the bar until arms are fully extended above your chest. 
3. By bending your arms, lower the bar towards your forehead.  Be sure that your upper arms stay in the vertical position the whole time. 
4. Return back to the original position. 
5. Repeat the process.
