Created by Andy Frisella, the challenge is a rarity in that it’s completely free.

It’s also not strictly a fitness challenge.

On hiswebsite, Frisella refers to it as a “transformative mental toughness program.”

However, you shouldn’t jump in headfirst without knowing all of the information.

The 75 Hard program is designed to completely uproot your life and habits but is it right for you?

Here’s everything you should know about 75 Hard.

Rules on chalkboard

These rules aren’t necessarily complicated, but they are strict.

In fact, the very first rule is that you cannot forsake any of the rules.

Yes, that’s right.

The second rule is that you must do two 45-minute workouts each day (viaCosmopolitan).

If that sounds like a lot, it is.

Registered dietician Albert R. Matheny believes that this workout plan is an unsustainable way to achieve your goals.

This rule fits in with one of the others, which is that no cheat meals are allowed.

Interestingly, it’s not specified what counts as a cheat meal.

Nevertheless, as with other aspects of this challenge, this rule could be problematic for some.

Woman reading

The first is that you must read 10 pages of a book per day (viaToday).

The final rule is that you must take a progress photo every day.

These photos are just for you and do not need to be shared with others.

For some, Andy Frisella’s no-nonsense approach could be the kick that’s needed.

For others, the challenge could exacerbate insecurities and accentuate existing issues.

Trainers also say that the challenge could easily cause exhaustion that quickly leads to burnout.
