WHAT IS THE AK PWR-Cord?

Introducing version 2 of the AK PWR-Cord— an all-in-one sprint resistance, timing, and performance data system designed for all levels of track, field, and court sport athletes. It is optimal for use on a variety of gym and playing surfaces including all types of track, playing fields, and courts. Built to use standalone or pair with the Kratos Performance App, it delivers lab-quality data at high throughput — directly on the track, field, or court.

Resistance Range:
- Up to 25 lbs resistance at distances up to 120m
- Up to 50 lbs resistance at distances up to 60m
- Comes with three standard resistance profiles: 1.) Direct resistance, 2.) Hill sprints, 3) Sled pulling
- Ability to program custom variable resistance profiles
- Workout Programming via PlayerID — Coaches pre-program athlete-specific resistance workouts. Resistance workout follows each athlete between team devices with no coach intervention required.
Designed For: Team sports, Track & Field, and anyone requiring portable resistance training

Please note: This is an acceleration / sprint training resistance device with a resistance of up to 50lbs, and it not designed for heavy resisted strength activities.

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.”
