Kettlebell training has been growing steadily in popularity because it focuses on basic training that requires functional, whole-body fitness. This is because lifting and controlling a kettlebell forces the entire body - and specifically the core muscles - to contract as a group. Kettlebell workouts engage multiple muscle groups at once, better mimicking physical activities such as digging, making them a perfect option for getting a whole body workout in a short time!
Unlike traditional dumbbells, the kettlebell's center of mass is extended beyond the hand. This allows you to perform swinging movements that are not possible with traditional dumbbells. Because more muscle groups are utilized in the swinging and movement of a kettlebell than during the lifting of dumbbells, kettlebell workouts are sometimes claimed to be more effective, better for improving joint mobility and to yield quick results.
