what muscles are used in a dumbbell bicep curl
The biceps curl is an exercise for the elbow flexors, which comprise the biceps brachii, brachialis and brachioradialis. You can emphasize each of these muscles by using a variety of grips. It is best to do biceps curls using dumbbells to ensure the elbow flexors of each arm are being worked to the same extent. Also, when you use dumbbells, it is best you do the biceps curls unilaterally, meaning one side at a time. By doing so, you can focus on one side at a time and better stimulate the muscles.
