Boxers are known to hide themselves away for intense training in the run-up to the fight. But Tyson Fury's not your average fighter.
Even the man himself recently claimed it was a "disgrace" to call him an athlete and, with just four weeks to go until his heavyweight title rematch with Wladimir Klitschsko, he's been caught on video at Welsh festival Gottwood.
On the same weekend that Ukraine's Klitschko was photographed in warrior-like training get-up, in a -150c sauna, UK ravers were going toe-to-toe with Fury on the dancefloor.
When asked about the upcoming bout on July 9, Fury apparently responded in typically confident fashion. "Fuck Klitschko" and "Klitschko no problem to me," one raver told The Sun.
We're not quite sure who was DJing when he was caught on camera, but Joy Orbison, Virginia, Roman Flügel and Tama Sumo were all on the line-up.
At least he got some cardio in.
Watch the video of him dancing to Artwork's 'Let Go Of My Acid' here.
