75 Hard alternative

A 75 Hard alternative you can do with friends

By the DuoShare team · Updated November 2026

If 75 Hard feels too extreme, a 66-day challenge with a friend is a research-based alternative. 66 days is the median time it took habits to become automatic in a 2010 UCL study. DuoShare runs 66-day challenges where you choose the habits, invite friends, and get one N/A day a week instead of restarting at day 1.

What 75 Hard is

75 Hard is a mental toughness program created by Andy Frisella: for 75 days in a row, two workouts a day (one outdoors), a diet with no cheat meals or alcohol, a gallon of water, 10 pages of nonfiction and a progress photo. Miss anything and you restart at day 1. DuoShare is not affiliated with 75 Hard.
