Built with cutting-edge innovation, the Zero Runner offers the same great workout as a treadmill, but because there’s no belt, deck, or power cord, it has significantly lower maintenance and electricity needs and offers a low cost of ownership. Smarter than a treadmill, the Zero Runner enables users to optimize their form, engage the core and concentrate on activating hamstrings and glutes. Independent hip and knee joints replicate natural walking, jogging or running motion without any stressful impact, and custom fit users of different sizes. Plus, with no fixed path like an elliptical and no moving belt like a treadmill, the Zero Runner allows for custom movement, while a stride length up to 58" lets users customize their stride. And because the Zero Runner is shorter than a treadmill, self-powered, and features whisper-quiet operation, it provides the utmost in flexibility.
