Tricep Skull Crushers Video - Also called Lying Triceps Extensions, if Skull Crushers aren't part of your triceps workout they definitely should be. Here's a quick video demo!
When people think of "big arms" the biceps seem to get all the attention. When someone says "flex for me" they likely mean show me your biceps. The triceps however, are more responsible for the size of the upper arm than any other muscle group. The triceps brachii muscle is the largest muscle of the arm and is composed of three heads (hence tri). There really isn't any way to ONLY target one part of the triceps despite what some muscle heads may say. The three heads of the muscle work in unison and are engaged with any triceps exercise. Having said that, like with most exercises you can definitely change how the muscle is worked by changing angles or using different variations. An ACE (American Council on Exercise) study found that the Lying Triceps Extension (or Skull Crusher) is 70% more effective than say a tricep push up. You may have already read our previous post on Bodyweight Skull Crushers. This is a great example of how a slight variation can give you "new" workout.
