Skull Crushers

Skull crushers deliver a deep stretch to the long head of the triceps in isolation exercises, fostering maximal growth and definition with proper skull crusher form. This lying extension minimizes momentum for pure tricep work.

Skull Crushers

📋 How to Do?

  1. Lie flat on a bench with an EZ-bar held above your chest, arms extended and elbows pointed straight up toward the ceiling.
  2. Bend your elbows to lower the bar slowly toward your forehead, keeping upper arms stationary and perpendicular to the floor.
  3. Extend your elbows to press the bar back up to the starting position, squeezing the triceps at the top for full contraction.
  4. Perform 3 sets of 10-12 reps, maintaining control to avoid any head contact.

Keep elbows tightly tucked and pointed upward during skull crushers, using a spotter for heavier loads, and lower only to forehead level to protect your head. Warm up with light extensions for elbow prep. If shoulder discomfort arises, switch to dumbbells.

💪 Working Muscles

Primary: Triceps Brachii (long head elbow extension); Secondary: Anterior Deltoids (shoulder stabilization); Forearms (grip during extension)

Equipment Needed: EZ-bar, flat bench

Difficulty: Intermediate

✨ Benefits

Skull crushers target all three tricep heads for balanced development, improving pressing lockout strength while adding serious arm mass. They enhance elbow stability in compound lifts.

🔥 Burned Calories

Burns Approx. 40-60 kcal per 10 min at moderate intensity

Metabolic Impact: Low, focused on tricep isolation

Common Mistakes

  1. Allowing elbows to drift outward, which stresses the shoulders and dilutes tricep focus.
  2. Selecting too heavy a weight, leading to loss of control and potential forehead impact.
  3. Performing partial reps without full stretch, missing the eccentric benefits for growth.
