Training tire Kwell XREVOLVE SMART offers new functional training challenges and gives strength training originality. Functional training introduces a tendency to practice with non-traditional products, such as truck and tractor tires. For that reason, Kwell created a Revolve - a professional overlay of truck tires. Kwell makes it possible to purchase both a lorry tyre and a specially manufactured coating that guarantees adequate hygiene. The revolve tire has a glamorous design and handles that are tightly attached to its surface. Thanks to this innovative product, you can do power exercises without losing style, professionalism and cleanliness.
