How to properly perform skull crushers with an EZ bar?

To properly perform skull crushers with an EZ bar, lie on a bench with your feet flat on the floor. Hold the EZ bar with an overhand grip, arms extended above your chest. Lower the bar towards your forehead by bending your elbows, keeping them stationary. Extend your arms back up to the starting position. Repeat for desired reps, ensuring proper form and control throughout the movement.
