The KingsBox competition kettlebells are made of 100% steel, which ensures a long life for them, despite their daily use. The main difference between the cast iron kettlebell and the competition Kettlebell is, in addition to the material, their size: the competition Kettlebells in fact do not vary in size. Regardless of whether you train with an 8 kg Kettlebell or a 32 kg Kettlebell, the dimensions of the ball and the handle will remain unchanged.
