Barbell Lying Extension

Target
Triceps

The barbell lying extension is the general triceps isolation movement most people know as a skull crusher, lowering the bar to the head or behind it while lying flat. The long range under tension is what makes it effective for triceps size, more so than heavier compound pressing where the triceps only work through part of the range. Keep the upper arms still and let the forearm do the moving.

How to Do the Barbell Lying Extension

  1. Lie flat on a bench with your feet flat on the ground and your head at the end of the bench.
  2. Hold the barbell with an overhand grip, hands shoulder-width apart, and extend your arms straight up over your chest.
  3. Keeping your upper arms stationary, slowly lower the barbell towards your forehead by bending your elbows.
  4. Pause for a moment, then extend your arms back up to the starting position.
  5. Repeat for the desired number of repetitions.

Muscles Worked
