About this episode

Alex St. John is six foot five, about 295 pounds, and three years into serious lifting when type 1 diabetes showed up mid-semester of his kinesiology degree, at a blood sugar of 504. His response was never "should I stop?" It was "how do I keep lifting?" Twelve years later he's a T1D exercise researcher in one of the top labs on the planet for this stuff, and he spends this hour translating science that usually reads like a tax form. The 48-hour insulin sensitivity bonus is real, and he confirms it. Exercise makes your insulin faster, not stronger (there's a Fast and Furious button involved). Fasted and fed lifting behave differently, and a seesaw explains why. Plus caffeine as low protection, what's in his gym bag, the endo who tried to "fix" his intentional bulk, an official kilt ruling, and a brand new Fastest Five Minutes world record.
