WHAT IS THE AK PWR-Cord?

Introducing the AK PWR-Cord—a new resistance and speed training tool designed to transform your approach to athletic performance. In collaboration with Kratos Fly Fitness, the AK PWR-Cord addresses a specific need for precision and portability across various sports.

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.

Developed by Experts, Backed by Research

This journey began with a conversation between ALTIS and Kratos Fly Fitness, a trusted name in flywheel technology. Kratos’s commitment to engineering excellence combined with ALTIS’s performance insights created the AK PWR-Cord series as a direct answer to the needs of coaches worldwide.

“We knew there was a huge gap in the market—a need for a portable, precisely calibrated resistance tool that didn’t tear up track, turf and field surfaces. Partnering with Kratos Fly Fitness, we’ve developed the AK PWR-Cord to be affordable, accurate, and ideal for team sports and track and field athletes alike.”
