Frank Mir nearly destroyed Jason ‘Mayhem’ Miller during training—find out how his brutal submission techniques turned a simple session into a near-death experience. Egos and refusal to tap lead to broken limbs and screams of pain—this is one training session you won’t believe!

Frank Mir’s Hardcore Training Approach: Nearly Killing ‘Mayhem’ Miller

Frank Mir, a legend in the UFC heavyweight division, is renowned for his formidable skills, both in the octagon and during training. As a former UFC heavyweight champion, Mir holds multiple records in the promotion, including the most submission wins in UFC heavyweight history (8) and the fastest submission in UFC heavyweight history (45 seconds). His reputation extends beyond his competition victories, especially due to his distinctive and intense approach to training.

Mir’s Approach to Training: No Mercy for the Unwilling

Mir has a unique philosophy when it comes to training: he believes in applying pressure slowly to ensure his submissions are properly locked in. “If you’re not tapping, it’s because I don’t have the move,” Mir explained on the JAXXON podcast, suggesting that if his opponent doesn’t submit, it’s a sign that the hold isn’t locked in correctly. This approach, however, can lead to dangerous consequences for those unwilling to tap out. Mir admitted, “I’ve broken guys’ arms and legs in the gym before,” illustrating the risks of testing his submission holds in training.

A Training Incident with ‘Mayhem’ Miller

One of Mir’s most memorable training stories revolves around his experience with former UFC fighter Jason “Mayhem” Miller. While training at Marc Laimon’s gym, Mir was told by Laimon to finish his practice session by tapping out his sparring partners. Mir turned up the intensity and began putting his partners in dangerous positions. During this session, he found himself grappling with Miller. Mir locked in a guillotine choke, and Miller, trying to escape, ran his feet up the cage in an effort to flip over Mir. Determined to teach Miller a lesson, Mir transitioned into kimura and began cranking it, causing Miller to scream in pain. “I was like, ‘I ain’t letting go. F*ck this. Today you’re going to learn!’” Mir recalled.

The Lesson: Respect the Submission

Mir’s story is a stark reminder of the importance of respect in training. The incident with Miller emphasized how egos can lead to dangerous situations in the gym. Mir’s no-nonsense approach to training demands that his partners tap when they’re in a compromising position—failure to do so can result in serious injury. The moral of the story: if you’re training with Frank Mir, leave your ego at the door.
