There are many benefits to using Reebok's Kettlebell, whether you're just getting started on a fitness program or you're already a trained athlete. Kettlebell exercises activate your core muscles, including your abdominals, hip, gluteals and back. Developing a strong and active core will help to prevent injuries, ensure the long-term health of your spine and teach your body to move more efficiently. Reebok's Kettlebell has a glossy vinyl coating in a calming colour. The handle is smooth and shaped to comfortably sit in your hand. These dumbbells are sold individually.
