I built the first one for my son Jordan when he was 10 years old. He trained on it for four years, and the results spoke for themselves: more explosive, faster, stronger. After seeing what it did for him, I started building the King Resistance Trainer by hand for other athletes.
It's a full resistance training platform. You can train vertical jump, speed, first-step, core, and overall strength, all from a single setup. Dozens of exercises, real resistance on every rep. The same principle behind the machines the pros use, at a fraction of the cost.
