Build Insane Triceps by Doing Skull Crushers – Laz – Tymoff

When it comes to achieving sculpted and powerful triceps, the “skull crusher” exercise stands out as one of the most effective and challenging movements. Renowned fitness expert Laz Tymoff has gained recognition for his comprehensive approach to fitness, and he particularly emphasizes the importance of skull crushers in triceps development. In this article, we’ll delve into Laz Tymoff’s expert guidance on how to build insane triceps by incorporating skull crushers into your workout routine.

The Anatomy of the Triceps

Before we delve into the skull crusher exercise, it’s crucial to understand the triceps’ anatomy. The triceps brachii consists of three muscle heads: the long head, the lateral head, and the medial head. To develop impressive triceps, it’s essential to target each of these muscle groups effectively. The skull crusher, also known as the “lying triceps extension,” does precisely that.

Laz Tymoff’s Guide to Skull Crushers

  1. Proper Form: Form is paramount when performing skull crushers. Lie on a bench with your feet flat on the floor. Hold an EZ curl bar or dumbbells with an overhand grip, arms fully extended. Lower the weight down towards your forehead while keeping your elbows stationary, and then extend your arms to the starting position.
  2. Range of Motion: Laz Tymoff emphasizes the importance of a full range of motion. Lower the weight as close to your forehead as comfortably possible without straining your elbow or shoulder joints.
  3. Mind-Muscle Connection: To get the most out of skull crushers, focus on the contraction and extension of your triceps. Feel the muscles working as you push the weight up.
  4. Weight Selection: Start with a manageable weight that allows you to complete the exercise with proper form. As you progress, gradually increase the weight to challenge your triceps.
  5. Sets and Repetitions: Laz Tymoff recommends incorporating skull crushers into your triceps workout with 3-4 sets of 8-12 repetitions. Ensure that you have adequate rest between sets for recovery.

Benefits of Skull Crushers

  1. Targeted Triceps Development: Skull crushers isolate the triceps, targeting all three heads of the muscle, making it a powerful exercise for triceps growth.
  2. Enhanced Strength: Regularly incorporating skull crushers into your workout routine can significantly improve your triceps strength, contributing to better overall performance in various exercises.
  3. Versatility: Whether you prefer using a barbell, EZ curl bar, or dumbbells, skull crushers can be customized to your equipment and fitness level.
  4. Aesthetic Appeal: Well-developed triceps provide an aesthetic and balanced look to the arms, which is particularly appealing for bodybuilders and fitness enthusiasts.


When it comes to sculpting impressive triceps, Laz Tymoff’s recommendation of incorporating skull crushers into your workout routine is solid advice. The exercise targets all three triceps heads, promoting growth, strength, and aesthetic appeal. However, it’s essential to practice proper form and gradually increase the weight as you progress. Remember that consistency and dedication are key to achieving insane triceps that make a lasting impression in the world of fitness.
