The 75 Hard Challenge is a rigorous 75-day program designed to build mental toughness through strict daily adherence to five key rules without any exceptions. The main challenge lies in the discipline required to complete all tasks every single day for 75 consecutive days; failure to do so means starting over from day one. The five critical daily tasks are:
- Follow a specific diet plan of your choice with no cheat meals or alcohol allowed.
- Complete two 45-minute workouts daily, with one workout required to be outdoors regardless of weather conditions.
- Drink one gallon (about 4.5 liters) of water each day.
- Read 10 pages of a nonfiction, personal development book daily (audiobooks do not count).
- Take a daily progress photo to track physical changes.
This challenge demands strict consistency and mental resilience, as missing even one task resets the entire 75-day count. It is described as a "mental toughness" program rather than just a fitness or diet plan, aiming to push participants beyond their comfort zones to foster long-term personal growth and discipline
. The hardest aspect is maintaining this unyielding routine without rest days, cheat meals, or modifications, which can be physically and mentally taxing and is not suitable for everyone. The challenge tests willpower, perseverance, and the ability to sustain intense commitment over an extended period
