Sal Di Stefano’s passion for fitness began when he picked up his first barbell at 13 years old. Any other teenager would have done a set of curls, but legend has it, Sal did squats. He was always different like that – and it wasn’t long until everyone would notice. 

At age 18, Sal started working as a personal trainer, becoming the youngest general manager at 24 Hour Fitness by 19. Not long after, he opened his own studio. Its reputation and success proved he was more than a personal trainer, but also a gifted businessman. And it was this entrepreneurial spirit that guided Sal to where we see him today. 

He is the voice of Mind Pump, a published author, and one of the most trusted and respected faces in the fitness industry. Sal is an indispensable podcast host: the one who summarizes research when Justin and Adam trip over scientific words, the proverbial guinea pig when there’s a new peptide, and the conductor trying his best to keep conversation on track when we all know it’s headed off the rails.
