How to do a skull crusher

  1. Lie flat on a bench and grip the barbell shoulder-width or slightly narrower with an overhand grip.
  2. Extend your arms so the bar is above your chest with a slight backward angle.
  3. Keeping upper arms fixed, bend your elbows to lower the bar toward your forehead.
  4. Stop just above your forehead, feeling the stretch in your triceps.
  5. Extend your elbows to press the bar back up to the starting position.
  6. Repeat for the desired number of repetitions with controlled tempo.

Form tips

  • Keep your upper arms stationary and elbows pointed forward, avoid flaring them out.
  • Lower the bar under control to protect your elbows and forehead.
  • Do not lock out aggressively; keep tension on the triceps throughout.
  • Maintain a stable core and keep your back flat on the bench.
