Set an incline bench to 45 degrees. Lie face down, chest supported, arms hanging. Hold a dumbbell in each hand, palms facing each other. Keep elbows slightly bent and stationary. Curl dumbbells up by flexing elbows, wrists straight. Squeeze at the top, contracting the brachialis. Slowly lower to the starting position. Repeat.
Maintain a controlled motion. Avoid swinging. Keep elbows stationary to isolate muscles. Exhale on the curl, inhale on the lower. Start with lighter weights, ensuring proper form. Keep chest in contact with the bench.
