Unlike traditional dumbbells, the true power of the kettlebell lies in its unique shape. Because the kettlebell's center of mass is extended beyond the hand, more muscle groups are utilized in the swinging and movement of a kettlebell as opposed to the lifting of dumbbells, thus producing a much more effective workout. For this reason, the kettlebell has attracted attention from fitness professionals and is being increasingly adapted for the general public.
