At a 45-degree bench angle, the EZ bar has to travel behind your head rather than to your forehead, which keeps the triceps under stretch and removes the dead spot at lockout that flat skull crushers have. The angled grips keep your wrists semi-neutral, and loading stays a notch below the flat barbell version, so treat it as a stretch-focused second movement.

How to do the Incline EZ-Bar Skull Crusher

  1. Set up an incline bench at a 45-degree angle.
  2. Sit on the bench with your back against the pad and hold the ez barbell with an overhand grip.
  3. Extend your arms fully overhead, keeping your elbows close to your head.
  4. Lower the barbell behind your head by bending your elbows, keeping your upper arms stationary.
  5. Pause for a moment, then extend your arms back to the starting position.
  6. Repeat for the desired number of repetitions.

Tip: Keep a slight bend at the top on lying extensions to protect the elbow, but lock out fully on cable pushdowns.

Muscles worked

Primary

Triceps · Arms

The triceps straighten the elbow, and overhead variations stretch the long head at the bottom, so you should feel the whole back of the upper arm working with a hard squeeze at lockout.

Secondary

  • Delts — The front delt holds the upper arm in position on overhead extensions and should feel tension but not be lifting.

Common mistakes

  • Elbows flaring out — on overhead and lying extensions the elbows should stay pointed forward or up, not out to the sides, since flaring turns it into a press.
  • Upper arm moving — the upper arm should be pinned in place and only the forearm should move; if the elbow drifts, drop the weight.
  • Not finishing the rep — take every rep to a full triceps squeeze; on pushdowns that means a complete lockout for a count.
  • Cutting the stretch — on overhead extensions let the weight travel down behind the head until you feel the long head stretch before pressing up.

Where it fits in a workout

Triceps extensions go after the presses in a push session or at the end of an arm day. Superset them with biceps curls.

When to talk to someone

  • Chest discomfort, feeling faint or lightheaded, or trouble breathing during or after exercise can be signs of a heart attack. In the US, call 911 right away; elsewhere, call your local emergency number.
  • Heart, metabolic or kidney disease, or symptoms like these when you are active: talk to your doctor before you start or step up training.
