The Cascade Ultra Runner not only gives you all the exercise benefits of a self powered curved treadmill, it gives you the option to add 4 levels of magnetic resistance to add higher intensity interval training. Walk or run at your own pace then add resistance to burn more calories and add variety to your workout. Comfortable handlebars accommodate all user sizes and facilitate different exercises. Premium anti-slip molded rubber slats with sealed bearings create an exceptionally quiet and smooth running surface and reduce friction wear and tear. The ultimate training tool, the Cascade Ultra Runner is fully commercial and built to last.
