Chris Duffin: The Mad Scientist of Strength | Lex Fridman Podcast #207

Chris Duffin walks Lex Fridman through the five-year journey to squat and deadlift 1,000 pounds for reps, explaining the biomechanics of spinal stability, breathing, and the foot-ground interface. He shares a harrowing childhood in the Northern California mountains involving rattlesnakes, the drug trade, foster care, and family suicide, and how he saved himself by taking custody of his sisters. The conversation covers his decision to burn his corporate life and fortune to build Kabuki Strength, the innovative equipment he engineered, and candid discussion of steroids and TRT. It closes with reflections on hard work, finding purpose, and facing mortality.
