Want to add amazing gains to your biceps? Supinating dumbbell biceps curls maybe just what you need to add mass to your arms. Supinating dumbbell biceps curls (also known as twisting dumbbell biceps curls) helps to achieve peak concentration of your biceps by taking advantage of a greater range of motion. The excercise can be achieved by rotating the forearms and thumbs outward while lifting the weight and can be performed while standing or while seated.
