The Bionic Runner is for serious runners who want a bio-mechanical training advantage, gives you the tough training sessions you crave, whilst protecting your body from the two main causes of injury – impact fatigue and over extension. The Bionic Runner utilizes a 60:40 swing/stance phase timing, which not only feels like running, but engages the same muscles as you would out on the road. Its foldable and made with durable materials up to the scientific standards. You may order one from Kickstarter.
