The Zero Runner ZR8, Octane’s new Zero Impact Running Machine, will take your running program to the next level. The Zero Runner is a new type of machine, a hybrid between a treadmill and an elliptical trainer so you get the best of both – a true running motion without the impact. Every detail of the quiet-running ZR8 was built for power, speed, endurance, efficiency, versatility, and recovery. The Zero Runner is different from traditional ellipticals due to its much larger range of motion. See the Zero Runner reviews on this page.
