Traditional bicep curls will target the biceps well. However, adding in different variations is always good for keeping workouts fresh, muscle shaping, and various training regimen. Rotating bicep curls start the dumbbell with a neutral grip (palms facing each other). As you curl up you’re going to rotate the dumbbell until the palm is up, or facing the shoulder. By incorporating the rotation you work not only the bicep, but also the forearm, and multiple stabilizer muscles in the back and shoulder. Try it out!
