Kai Chang

Kai Chang was a fit competitive rower 15 years ago. He was in great shape! After gaining 50 pounds in recent years he decided to make a change. In this video, Kai talks about his CrossFit training. Kai started CrossFit because it produced effective results with short, high-intensity workouts, which fit well into his busy lifestyle. He used his self-tracking data from CrossFit to motivate (and punish) himself, even when the numbers were bad.
