These are: follow a nutrition plan of your choice with no cheat meals or alcohol allowed, complete two 45-minute workouts, drink a gallon of water, take a progress picture and read 10 pages of a non-fiction book each day.
I watch Youtube videos of people who had successfully completed the challenge and absorb their tips: start drinking water as soon as you wake up, get those pages read pronto, meal prep to ensure you stay on track with your diet.
I had no problem following the reading rule and happily read my ten pages of non-fiction - admittedly not the kind of self-help tome Frisella suggested, instead I read an historical true crime book - and most surprisingly, I really enjoyed the two workouts a day.
Oh, and if you fail to complete one of these tasks, you have to restart the challenge and go back to day one.
On TikTok alone, the hashtag 75 Hard has been viewed over a billion times and Frisella claims that over a million people around the world have completed the challenge.
