Build Insane Triceps by Doing Skull Crushers – Laz – Tymoff

For fitness enthusiasts seeking to sculpt extraordinarily defined and voluminous triceps, the inclusion of skull crushers into training regimens emerges as a potent maneuver. Colloquially termed triceps extensions, this exercise exhibits meticulous precision in targeting the triceps brachii muscles of the upper arm.

Anatomy of the Triceps by Doing Skull Crushers

Comprehending the rationale behind skull crushers necessitates familiarity with triceps anatomy. The triceps comprise three distinct heads – the lateral, medial and long heads. Each head originates from the humerus bone of the upper arm and converges to attach to the olecranon process of the ulna.

This multi-headed configuration enables the triceps to fulfill several functions, primarily elbow extension. The long head stretches over both shoulder and elbow joints, imbuing the capacity for shoulder extension and adduction. The medial head contributes to arm adduction while the lateral head engages in elbow extension.

Benefits of Skull Crushers

The integration of skull crushers into training regimens confers numerous advantages:

Isolated Triceps Targeting

By stabilizing upper arms and moving only the forearms, skull crushers achieve unparalleled isolation of the triceps. This enables peak contraction and tension.

Muscle Hypertrophy

The controlled eccentric and concentric phases mechanically load the triceps, creating microtears in muscle fibers that stimulate growth through hypertrophy.

Improved Arm Definition

Increased triceps development enhances that coveted defined and sculpted arm appearance.

Elbow Extension Strength

Bolstering triceps power translates into greater elbow extension force production for pushing, lifting and throwing activities.

Complement Compound Lifts

Robust triceps generated via skull crushers stabilize elbows when performing presses, enhancing compound lift performance.

Variations for Different Fitness Levels

Numerous variations including hand positioning, inclination angles and resistance styles allow customization for any fitness enthusiast.

Proper Skull Crusher Technique

Perfecting skull crusher technique is paramount for safety and optimal triceps activation.


  • Lie supine on a flat bench. Plant feet firmly on the floor.
  • Grasp a barbell or dumbbells with palms facing up and hands slightly wider than shoulder-width.


  • Initiate movement by bending elbows and lowering weights towards forehead.
  • Keep upper arms stationary throughout movement.
  • Lower until weights nearly touch forehead then reverse direction.
  • Focus on flexing triceps to lift weights back to starting position.
  • Inhale during eccentric lowering phase, exhale during concentric lift.
  • Avoid arched back, flared elbows and using momentum.


  • Initiate lift from full stretch position for constant tension.
  • Pause briefly at bottom stretch position.
  • Visualize triceps contraction throughout full range of motion.


Skull crushers offer excellent customization for trainees of all levels:


  • Lightweight or bodyweight variation
  • Limit range of motion
  • Focus on mastering form and technique


  • Increase resistance
  • Full range of motion
  • Use barbell or dumbbells
  • Tempo focused execution


  • Weighted chains or bands for variable resistance
  • Superset with complementary exercise
  • Decline bench skull crushers
  • Overhead single arm extensions

Sample Skull Crusher Workouts

Integrating skull crushers into weekly training splits stimulates maximal triceps growth.

Workout A

  • Overhead Barbell Extension 3 x 10
  • Seated Dumbbell Overhead Extension 3 x 12
  • Rope Pushdowns 3 x 15

Workout B

  • Overhead Cable Extensions 2 x 15

Workout C

  • Diamond Pushups 3 x Failure
  • Barbell Skull Crushers 4 x 8-10
  • Triceps Dips 3 x 12-15

Nutrition Tips

Fueling skull crusher training for insane triceps requires nutrition that supports hypertrophy:

  • Consume adequate protein – aim for 0.5-1g per pound of bodyweight
  • Time protein intake before and after workouts to maximize uptake
  • Carbohydrate intake fuels intense sessions
  • Hydrate consistently, especially during workouts
  • Allow muscle protein synthesis phase after workouts (24-48 hrs)
  • Consider creatine supplementation to boost power output

Recovery Tips

Allowing proper recovery enables optimal adaptation and growth:

  • Get adequate sleep (7-9 hrs) for muscle protein synthesis
  • Use massage, stretching, foam rolling to alleviate muscle tightness
  • Avoid overtraining triceps
  • Listen to your body and take needed rest days
  • Stay active on rest days with light cardio or yoga
  • Manage outside life stresses that can hamper recovery

In summary, the integration of skull crushers into training provides unparalleled triceps targeting and development. When performed with proper technique and coupled with strategic nutrition and recovery, skull crushers can help you build insane triceps!
