Episode Overview

Early UFC legend and two-time UFC heavyweight champion Mark Kerr — subject of the documentary The Smashing Machine — joins Joe for a three-hour conversation about his extraordinary career, the evolution of fight training, and his long road back to himself. Kerr describes his peak training regimen: 15 rounds a day with fresh partners cycling every third round, a volume that would be considered extreme even by modern standards. He talks about fight morning nerves and the small rituals that kept him functional, heart rate monitoring as a primitive but useful tool from 25 years ago, and the experience of rewinding a tape 50 times to understand something a training partner was doing that he still can't fully explain. A memorable thread covers a multi-millionaire friend who fights wildfires with a backpack and a shovel not for necessity but because it's genuinely hard — and Kerr's admiration for that. The episode closes on a note of hard-won peace: after everything he went through publicly and privately, Kerr says he is completely okay with himself — and that it took a very long time to get there.
