Our patent-pending design enables you to perform dumbell and kettlebell exercises while having the ability to change the weight, rather than having to purchase individual kettlebells or dumbells. This has the potential to save thousands of dollars! The two-handle feature allows for one-handed and two-handed exercises, as well as the benefit of stability training. The Ropebell is lightweight and easy to store, making it great for home gyms and on the go! Our rope is abrasion-resistant and manufactured in Maine, and all Team Sciath products are made in the USA.
