The zero runner is a totally new way to train because it replicates a true running motion but without any impact. There is no fixed path so it fits users of all sizes and you can decide what type of workout you want to do. You can simulate walking with short strides, or take full advantage of the zero runner’s design, and increase speed to replicate an all-out running motion with strides up to 58 inches. You will work the same muscles as you do when running and burn a lot of calories but without all the impact to your body. Plus, it’s self-powered and whisper quiet so it can go anywhere in your house.
