This exercise combines the benefits of the preacher curl and the EZ-bar, emphasizing bicep isolation and reducing wrist strain. The preacher bench supports the arms, preventing momentum and encouraging strict form. This exercise targets the lower biceps, enhancing muscle definition and strength, and is particularly effective for building a peak in the biceps.

1. Sit on a preacher bench with an EZ-bar.
2. Rest your arms on the pad and curl the bar towards your shoulders.
3. Squeeze your biceps at the top of the movement.
4. Slowly lower the bar back to the starting position.
