How to Do Barbell Skull Crushers: Form and Top Tips

Master the barbell skull crusher with our step-by-step guide. Learn proper form to build stronger triceps and avoid common elbow injuries.

How to Perform

  1. Lie flat on a bench and hold a barbell or EZ-curl bar with a shoulder-width overhand grip.
  2. Extend your arms fully to hold the bar directly above your upper chest or neck area.
  3. Keeping your upper arms stationary and elbows tucked, slowly lower the bar by bending your elbows until it is an inch above your forehead.
  4. Pause for a brief moment at the bottom of the movement to maintain control and tension.
  5. Contract your triceps to extend your arms back to the starting position without locking out the elbows aggressively.
  6. Maintain a slight backward angle with your upper arms throughout the set to keep constant tension on the muscle.

Common Mistakes

  • Flaring the elbows out to the sides during the descent
  • Moving the upper arms back and forth rather than keeping them fixed
  • Lowering the bar too quickly or bouncing it off the forehead
  • Using excessive weight that compromises form and strains the elbow joints
