The Fitness Mad 12kg Cast Iron Kettlebell is an extremely versatile piece of gym equipment which can be used for hundreds of different exercises. Besides giving you a good cardio workout, it can be used for weight training in the same way as dumbbells, to tone and build muscle in the arms, shoulders and back. Or swing with one or two hands to target the arms, shoulders, core and legs. Kettlebells are highly effective at burning fat, developing core strength, tone and strengthen most muscle groups in the body and can also help build agility, stamina and balance.. This cast iron kettlebell weighs 12kg but other weights from 4kg to 24kg are also available (see our website). The kettlebells are made with an oversized powder coated handle to help you maximise your motion and also get a fantastic grip whilst you work out. This kettlebell has a green heavy duty vinyl skin which has the weight clearly displayed on the side and helps to protect your floor.
