Massiel Diaz spent more than a decade under-eating and over-training, chasing the stick-thin look of the Paris Hilton era and comparing herself to physiques that, she later learned, were built on performance-enhancing drugs.
In this crossover episode, recorded with Massiel's own show, she and Nick unpack why diets fail without accountability, why women should lift instead of living on cardio, and how protein and carb cycling fuel performance.
Nick gets candid about coming off testosterone, the truth behind influencer physiques, how fitness shows up in sales calls and promotions, and why he left a $150K job at Chevron to build PetroFit.
