How to EZ-Bar Skullcrusher

  1. 1

    Using a close grip, lift the EZ bar and hold it with your elbows in as you lie on the bench. Your arms should be perpendicular to the floor. This will be your starting position.

  2. 2

    Keeping the upper arms stationary, lower the bar by allowing the elbows to flex. Inhale as you perform this portion of the movement. Pause once the bar is directly above the forehead.

  3. 3

    Lift the bar back to the starting position by extending the elbow and exhaling.

  4. 4

    Repeat.

Common Mistakes

  • Focus on the mind-muscle connection — feel the target muscle working through each rep.
  • Use a controlled tempo of 2 seconds up, 2 seconds down to eliminate momentum.
  • Avoid locking out aggressively at the top — stop just short of full extension to keep tension on the muscle.
