Kettlebells! It sounds heavy... and for good reason! Specially molded from cast iron with an inlaid GladiatorFit logo and weight, these kettlebells are made specifically for working out. The handles have standardized colors for the different weights. They are available in a range of weights from 4kg to 36kg and are also popular with athletes looking to shape and tone their bodies. Lifting and controlling a kettlebell forces the abdominal muscles to tighten and can work every muscle in the body with just a few exercises! This seemingly ordinary item is actually a great ally for a complete workout and in addition to being versatile, it is solid. The cuff designs are formed from a colored line.
