75 Hard requires you to complete five specific tasks every single day for 75 consecutive days, with no days off, no modifications, and no exceptions. If you miss any single task on any day, you start over from Day 1. The program was created by entrepreneur Andy Frisella as a mental toughness challenge, not a fitness plan.
The Five Daily Rules
Every day for 75 straight days, you must complete all five of these tasks:
- Two 45-minute workouts: You must exercise twice a day, with each session lasting at least 45 minutes. One of the two workouts must be outdoors, regardless of weather. The workouts must be separate sessions, not one 90-minute block.
- Follow a diet with no alcohol or cheat meals: You choose a structured eating plan and stick to it for the entire 75 days. There is no specific diet prescribed. The only firm restrictions are zero alcohol and zero cheat meals for the full duration.
- Drink one gallon of water: You must consume a full gallon (roughly 3.8 liters) of water each day.
- Read 10 pages of nonfiction: The reading must be from a physical book, not an audiobook. It needs to be nonfiction, typically something related to self-improvement, business, or personal development.
- Take a daily progress photo: A photo of yourself each day to track visible changes over the course of the challenge.
The Restart Rule
The defining feature of 75 Hard is its all-or-nothing structure. If you fail to complete even one of the five tasks on any given day, you go back to Day 1. Not Day 2, not the previous week. Day 1. This applies whether you miss a workout on Day 3 or forget your progress photo on Day 70. There is no partial credit and no grace period.
This reset mechanic is the core of the program’s philosophy. Frisella designed 75 Hard as a test of discipline and consistency rather than a workout program, and the restart rule is what separates it from a typical fitness challenge.
No Rest Days, No Modifications
The official program includes no built-in rest days for the entire 75-day stretch. That means two workouts a day, seven days a week, for two and a half months straight. Exercise scientists have raised concerns about this. Penn State sports medicine researchers have pointed out that recovery time is essential for the body, and they generally recommend no more than six training days per week, even for experienced athletes.
The program also makes no formal allowance for injury, illness, or travel. If you can’t complete a task for any reason, the clock resets. This rigidity is intentional from Frisella’s perspective, but it’s worth understanding that the challenge was not designed by medical or fitness professionals.
Water Intake Considerations
A gallon of water per day is significantly more than most people typically drink. While exercising twice daily does increase your hydration needs, a full gallon isn’t the right amount for everyone. Drinking too much water can disrupt your body’s electrolyte balance, which affects how your muscles and heart function. St. Vincent’s Medical Center advises paying attention to urine color as a practical gauge: if it’s light yellow or nearly clear, you’re already well-hydrated and can ease off.
What the Program Is (and Isn’t)
75 Hard is explicitly framed as a mental toughness program, not a fitness or weight loss plan. There are no recommended exercises, no structured training progression, and no nutritional guidelines beyond “pick a plan and don’t deviate.” The challenge doesn’t care whether your workouts are walking or weightlifting, or whether your diet is keto or plant-based. The point is sustained daily discipline across multiple areas of life simultaneously.
For people who already have a solid exercise habit and want a structured commitment challenge, the format can provide accountability. For beginners or anyone returning to fitness after a long break, the lack of rest days and the twice-daily workout requirement carry real injury risk. Penn State researchers recommend that people new to exercise start with just 15 minutes a day, five days a week, and build from there, since starting with too much volume too quickly is one of the most common causes of injury.
The 75 Soft Alternative
A modified version called 75 Soft has emerged for people who want the structure without the extreme demands. It reduces workouts to one 45-minute session per day, includes one active recovery day per week, and allows for some dietary flexibility. The core habits of reading, hydrating, and daily exercise remain, but with built-in room for rest and a more sustainable pace.
