So convenient, can be used while sitting down. The UREVO 2 in 1 Under Desk Treadmill is designed, as the name suggest, as an under-desk walking machine meaning you can workout while working. The clever construction can also be converted into a regular running machine, its 5-layer non-slip running belt with silica gel support column to cushion the impact on the joints. The design is foldable and on wheels for ease of transport and storage.
