Overview

The PowerBlock Alternating Hammer Curl — Seated performed while seated helps build wrist and forearm strength. At the same time this exercise develops the brachioradialis.

• Starting with one arm, bend the elbow and pull the dumbbell up to the shoulder, and then lower it.
• Repeat with the other side.

• Leaning back excessively.
• Swinging the body.
