Hammer Curls with dumbbells

This exercise helps to make your upper arms and forearms overall stronger and thicker by targeting different muscles than regular Biceps Curls. Using dumbbells makes it easy to perform and well-suited for beginners. Regular hammer curls are performed with both arms simultaneously.
