【High-quality Material Used】Our 3 pcs kettlebell set is made of concrete which is filled with cement inside. Heavy duty gear means burning more calorie. Besides, our kettlebell is integrated, the one with no welds or seams. It is also a priority when you are working out.||【Thoughtful Design for Better Kettlebell】Each of our kettlebell is firm, the film preventing it from being chipped. The wide but not so smooth handle is much easy to grip even when your palms are sweating. Also suitable for amateurs or those with no experience at all.||【Flat Bottom For More Exercise】Kettlebells are more stable with flat bottoms. Ideal for those exercise on the ground. Thus you can do more pushups, renegade rows, handstands or mounted pistol squats. Great to use them indoor & outdoor, even under harsh condition.||【Three Weight Levels Choose From】This kettlebell set includes three different weight levels: 5+10+15 Lbs. And color-coded numbers on the body make it easy to identify the weight.
