Kettlebells are extremely popular all over the world as they have the ability to help strengthen and tone a wide variety of muscles including the biceps, triceps, deltoids, trapezius, quads, glutes, calves, hamstrings and core abdominals.
Although they can be used in much the same way dumbbells are used, kettlebells are also extremely effective when combined with high-intensity training programs such as CrossFit and circuit training. Combining Kettlebells to your workout routine can help boost your cardio stamina and increase your endurance.
