The ZR8000 features a heavy-duty frame for exceptional performance, as well as cordless, virtually silent operation, a lower cost of ownership, and fewer maintenance requirements than treadmills. Because the ZR8000 has no belt or motor, facility owners save money on electricity as well as costly downtime and treadmill repairs. The Zero Runner takes care of equipment maintenance and service for you. Club owners and members win big when the cardio floor is fueled like never before. The ZR8000 has all of the advantages of a treadmill, but it's even better. The ZR8000 creates a buzz on the cardio floor by combining the best of a treadmill and an elliptical for standout workouts that mimic real running. And, unlike a treadmill, the ZR8000 provides valuable benefits to clubs: no electricity costs, quiet operation, and minimal maintenance and service requirements.
