Two of the most famous martial artists to ever take Hollywood by storm also shared the mats in a training session that many fans never knew about. In 1984, middleweight Karate champion Chuck Norris and Karate phenom Jean-Claude Van Damme linked up on what appears to be a German TV program, where the pair trained together.

Unfortunately, the clip doesn’t exactly show much of Van-Damme, however both men also take part in a side-by-side interview towards the end of the video. While the video is in German, via the YouTube player, subtitles can be generated in English, with surprising accuracy.

While at 77 years old Norris isn’t as active in Martial Arts like he once was, Van-Damme is still as active as ever, even recently training with Stockton California’s Diaz Brothers several times. In addition, the trio were pictured numerous times hanging out together.
