Adjust the bench so your upper arms rest comfortably on the pad. Sit, gripping dumbbells with a neutral grip. Position your upper arms on the pad, elbows slightly bent. Start with arms extended downward. Curl the weights up by flexing your elbows, keeping your upper arms stationary. Raise until forearms are vertical. Pause briefly at the top. Slowly lower to the starting position. Repeat.
Keep wrists straight. Avoid momentum; control the movement. Shoulders relaxed, remain on the bench. Exhale on the curl, inhale on the lower. Engage your core for stability. Start with lighter weight.
