Build Massive Arms with Skull Crushers – Technique, Benefits and Variations

This guide will teach you how and why you need to include Skull Crushers in your training.

What are Skull Crushers?

Skull Crushers are a lying barbell exercise that targets and isolates the triceps.

Muscles Worked by Skull Crushers

The primary muscles worked are the triceps. The exercise also strengthens the wrists, forearms and shoulders to a lesser degree.

Triceps: Skull Crushers isolate the triceps through deep elbow flexion whilst forcing the shoulders and wrists to stabilise and balance the load throughout the full range of motion.

Shoulders: The shoulders are worked during the exercise but not as intensely as they might be with a Strict Press or Handstand Push Up for example. This means that the scapular stabilisers and rear deltoids must work hard to balance the movement.
