What Is 75 Hard? Rules, Risks, and Safer Alternatives

The 75 Hard program demands two 45-minute workouts a day, a gallon of water, and no cheat meals for 75 consecutive days, yet medical experts find no scientific evidence to support its rigid structure. Here’s what the rules actually look like, what clinicians say about the risks, and how to approach it more safely.

Duration of 75 Hard: 75 consecutive days ·
Creator of 75 Hard: Andy Frisella ·
Total daily tasks required: 5 ·

Minimum outdoor workout duration: 45 minutes ·
Water intake daily: 1 gallon (3.8 liters)

Five key facts about 75 Hard, one pattern: the program is rigid by design yet unsupported by clinical evidence.

What are the rules of a 75 Hard?

Daily tasks required

• Two 45-minute workouts per day, one of which must be outdoors (Fox News).
• Follow a strict diet — no cheat meals, no alcohol (Fox News).
• Drink 1 gallon (3.8 litres) of water every day (Fox News).
• Read 10 pages of nonfiction (Fox News).
• Take a daily progress photo (Fox News).

Six daily specs, one pattern: every task is mandatory, and there is zero flexibility.

Failure and restart rules

• Missing any one task — even a single sip of alcohol — means restarting from day 1 (Cleveland Clinic).
• No substitutions or modifications are permitted (REP Fitness UK (fitness retailer)).
• The count resets even if you are sick, injured, or on holiday (Los Angeles Times).

Allowed and forbidden items

• Black coffee is permitted if it fits your chosen diet (Fox News).
• No alcohol, no sugary drinks, no snacks outside the diet plan.

Is 75 Hard unhealthy?

Potential physical risks

• Cleveland Clinic warns the two-a-day structure may do more harm than good for people without a strong fitness base, especially those with chronic conditions (Fox News (citing Cleveland Clinic)).
• Ruby Oak Nutrition, a registered dietitian practice, states the program has “virtually no proven benefits” and “a lot of risks”, including normalising disordered behaviour (Ruby Oak Nutrition).
• HUM Nutrition says the strictness is unrealistic and unsustainable for the average person, with a high risk of burnout (HUM Nutrition).

Mental health concerns

• Ruby Oak Nutrition warns the challenge can foster orthorexia — an unhealthy obsession with “clean” eating (Ruby Oak Nutrition).
• HUM Nutrition advises that people with a history of eating disorders, OCD, or chronic health conditions should avoid the program entirely (HUM Nutrition).

Lack of scientific evidence

• Cleveland Clinic reports there is little scientific evidence backing any element of the 75 Hard approach (Cleveland Clinic).
• WebMD echoes the call for more research before the benefits and risks can be properly understood (WebMD).

What does 75 Hard do to you?

Mental discipline and toughness

• Creator Andy Frisella describes the program as a “mental toughness” challenge, not a fitness program (Los Angeles Times).
• REP Fitness UK agrees it is a discipline challenge rather than a trainer-designed regimen (REP Fitness UK).

Physical changes and weight loss

• Forbes describes 75 Hard as a wellness program that tests both mental and physical limits (Forbes (editorial publication)).
• Participants report weight loss and improved routine adherence, but dropout rates are high (HUM Nutrition).

Common reported outcomes

• Many who finish say they feel more disciplined and confident.
• Others report overuse injuries, exhaustion, and a strained relationship with food (Ruby Oak Nutrition).

Can you drink coffee during 75 Hard?

Caffeine and permitted beverages

• Coffee is allowed only if it is black and fits the participant’s chosen diet (e.g., no sugar, cream, or milk) (Fox News).
• The diet rules are self-selected but must be followed with zero exceptions.

Diet restrictions in 75 Hard

• Many participants choose a no‑sugar or low‑carb diet.
• Alcohol is strictly forbidden for the entire 75 days (Fox News).

The implication: if your diet allows black coffee, it’s fine — but the moment you add cream, you break the rules and restart.

Does a 45-minute walk count for 75 Hard?

What qualifies as a workout

• Yes, a continuous 45-minute walk at a moderate pace counts as one workout (Fox News).
• The other daily workout must be outdoors — a walk can satisfy that requirement.

Outdoor workout requirement

• One of the two daily workouts must be done outdoors, regardless of weather (Cleveland Clinic).
• Indoor alternatives (e.g., gym sessions) are allowed only for the second workout.

The trade-off: a 45-minute walk is acceptable, but any shorter or less intense activity does not count — no exceptions.

How does 75 Hard compare to 75 Soft?

Two programs, one key difference: flexibility.

What this means: 75 Soft removes the all-or-nothing pressure while still encouraging daily movement and mindful habits. Health experts recommend it for long‑term adherence (Cleveland Clinic).

What is 75 Hard for beginners?

Tips for starting the challenge

1. Consult a doctor before beginning — especially if you have any pre‑existing conditions (HUM Nutrition).
2. Gradually increase your fitness level for a few weeks beforehand to reduce injury risk.
3. Choose a diet that is strict but not extreme — avoid highly restrictive plans that could lead to burnout.
4. Prepare a system to track your daily tasks, such as a 75 Hard PDF template or a habit‑tracking app.
5. Set up your environment for success: stock compliant foods, schedule workout times, and remove temptations.

Common mistakes to avoid

• Underestimating the water intake: 1 gallon (3.8 L) is a lot — plan bathroom breaks accordingly.
• Skipping the outdoor workout on bad weather days — plan indoor alternatives that still meet the 45‑minute requirement.
• Choosing an overly ambitious diet that is impossible to maintain for 75 days.
• Neglecting sleep and recovery — two workouts a day demand extra rest (HUM Nutrition).

“Cleveland Clinic reports there is little scientific evidence backing the 75 Hard approach, and the program’s rigid two-a-day structure may do more harm than good.”

Cleveland Clinic (health system)

“Forbes describes 75 Hard as a wellness program testing mental and physical health, noting that its popularity has grown despite the lack of clinical backing.”

Jonathan H. — Forbes Health (editorial publication)

For anyone considering 75 Hard, the choice is clear: either commit to the rigid program and accept the documented risks, or choose a more flexible alternative like 75 Soft that builds sustainable habits without the all‑or‑nothing penalty.
