How to Perform Barbell Skull Crusher

The skull crusher is an isolation exercise that targets the triceps by emphasizing elbow extension under load. Performed lying on a bench with a barbell or EZ-bar, the movement involves lowering the weight toward the forehead or behind the head while keeping the upper arms stationary, then extending the elbows to return to the starting position. Controlled tempo and strict form help maximize triceps activation while minimizing strain on the elbows and shoulders.
