The Cascade Ultra Runner not only gives you all the exercise benefits of a self-powered curved treadmill, but it also 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 users of all sizes and support a variety of exercises. Premium anti-slip TPE slats with sealed bearings create an exceptionally quiet, smooth-running surface and reduce friction and wear and tear. The ultimate training tool, the Cascade Ultra Runner is fully commercial and built to last.
