WHY THE AK PWR-Cord?
Our partnership with Kratos Fly Fitness began with a simple vision: to design a resistance training tool that solves the problems coaches face with traditional sleds and tires—tools that tear up surfaces, deliver inconsistent resistance, bounce unpredictably, and take up too much space.
This device changes all of that. It's smooth, consistent, and quiet. It protects your training surface, offers scalable resistance without the need for extra plates, and stores easily when not in use. Built with the coach in mind, it delivers the performance benefits of resisted sprinting—without the usual hassle.
Drawing from feedback from top coaches and inspired by Kratos Fly Fitness's reputation for quality engineering, the AK PWR-Cord brings innovative resistance training within reach—without compromising on precision or durability.
