Stefi Cohen
Stefi Cohen’s day job is to work as a physical therapist but her side gig of bodybuilding is what’s earned her internet fame. Stefi holds an impressive 25 records including deadlifting 456 pounds, squatting 446 pounds, and bench pressing 226 pounds.

Cohen has a book, YouTube channel, and podcast — all three of which she uses to “make confusing fitness topics easy to understand.” These days, the 31-year-old is focusing her energy on professional boxing.
