Which dumbbell is best for beginners?

When you're first getting started with beginner dumbbell exercises, Moore suggests keeping it simple and choosing light dumbbells—ideally between five and 10 pounds. "You want to be able to learn the exercise movements correctly and execute proper form, so you don't want the weight to be too heavy," she explains.
