The five daily rules
Andy Frisella published 75 Hard in 2019 and is emphatic about what it is. The program's own page states, in capitals, that this is not a fitness challenge — it calls itself a transformative mental toughness program. Reading the rules with that framing in mind explains most of the design decisions that otherwise look arbitrary.
| Daily rule | The detail that catches people |
|---|---|
| Two 45-minute workouts | They must be separate sessions with a gap between them — not one 90-minute block. At least one must be outdoors, in whatever weather arrives. |
| Follow a diet | You pick any structured diet; the program does not prescribe one. No cheat meals and no alcohol, for all 75 days. |
| 1 gallon of water | A US gallon, about 3.8 litres. |
| Read 10 pages | Non-fiction or personal development, read rather than listened to. Audiobooks do not count. |
| Take a progress photo | Every day, all 75 days. No requirement to post it anywhere. |
The rule the whole thing turns on
Miss any task, on any day, and you start over at day one. There is no partial credit, no doubling up tomorrow, no negotiating with yourself about whether a 40-minute session was close enough.
This is the rule people argue about, and it is also the only rule that makes the program what it claims to be. If the point were fitness, restarting on day 62 over a forgotten photo would be absurd — you would simply take two photos on day 63. The point is that the line does not move, which is precisely what makes it uncomfortable.
Worth knowing before day one. Two 45-minute workouts, a gallon of water, ten pages and a photo is around two hours a day, every day, for two and a half months — including the day you fly, the day you are hungover from a wedding you did not attend because alcohol is banned, and the day you are ill. The failure rate is not a mystery. It is arithmetic.
Is it free?
The rules are public and cost nothing to follow. Frisella sells books and an app around the program, but no purchase is required — a notebook and a water bottle will do.
The parts that need a real caution
Most coverage of 75 Hard treats the difficulty as purely motivational. Some of it is not:
- No rest days for 75 days. Two daily sessions with zero programmed recovery is where injuries and overtraining come from, particularly for anyone who was not already training most days. Making one of the two sessions a genuine walk is the standard way people survive the volume.
- A fixed gallon is not universal advice. Healthy kidneys handle it, but it is a real risk with kidney disease, heart failure, or medication that affects fluid balance — and drinking far beyond thirst can dilute blood sodium.
- Rigid food rules plus daily photos plus daily weighing thoughts is a combination that can go badly wrong if you have a history of disordered eating. This one is worth taking seriously rather than pushing through.
None of this makes the program bad. It makes it a program that some people should modify — and modifying it means you are doing something else, which is entirely allowed as long as you are honest that it is no longer 75 Hard.
If you want the structure without the restart clause
The restart rule is the part that ends most attempts, and it is separable from the rest. Keeping every other rule but replacing “start over” with “log the miss and carry on” is close to what 75 Medium already is. Dropping to one workout a day and allowing social drinking is 75 Soft. Both are complete challenges rather than a failure to do this one.
