Lie face down on an incline bench, gripping dumbbells with palms facing up. Curl the weights towards your shoulders, keeping your upper arms still and concentrating on your forearm muscles. Lower the weights slowly to return to the initial position.
Keep tension on your biceps throughout the entire range of motion. Execute each rep with a slow, controlled pace. You can substitute dumbbells with an EZ curl bar. Focus on isolating the biceps muscle. Prevent any movement in your upper arms.
