“70 Hard” isn’t an official program. What you’re likely looking for is 75 Hard, a 75-day lifestyle challenge created by motivational speaker and entrepreneur Andy Frisella in 2019. The name gets misremembered often, but the concept is straightforward: follow five strict daily rules for 75 consecutive days, and if you miss even one task on any day, you restart from day one.
The Five Daily Rules of 75 Hard
Every single day for 75 days, you complete all five tasks. No exceptions, no modifications, no days off.
- Two 45-minute workouts. One must be outdoors regardless of weather. The two sessions need to be at least three hours apart.
- Follow a nutrition plan with zero cheat meals. You pick the diet, but you stick to it perfectly. No alcohol at all for the entire 75 days.
- Drink one gallon of water. That’s 3.8 liters, every day.
- Read 10 pages of a nonfiction book. Audiobooks don’t count. You have to physically turn pages.
- Take a daily progress photo.
The restart rule is what makes 75 Hard distinctive. Forget your progress photo on day 60? You go back to day one. Skip a workout on day 73? Back to the beginning. Frisella frames this as the entire point: the challenge is designed to build mental toughness, not just physical fitness. He’s explicitly against any modifications, arguing that changing the rules to make them easier is “the whole problem of your entire life.”
Why People Search for “70 Hard”
Most people who type “70 Hard” are either slightly misremembering the name or have seen someone on social media doing a shortened or modified version. Informal variations float around online, where people trim the duration to 70 days, reduce workouts to one per day, or allow rest days. None of these are endorsed by Frisella. There’s also a popular alternative called 75 Soft, which keeps the same general framework but removes the penalty for missing a day and doesn’t require two-a-day workouts.
What a Gallon of Water Actually Means
The gallon-a-day water requirement sounds simple but deserves a closer look. The Mayo Clinic notes that the average healthy adult needs roughly 11.5 to 15.5 cups of total fluid per day (2.7 to 3.7 liters), and that includes water from food and other beverages. A full gallon, at 3.8 liters, sits at or above the upper end of that range from drinking water alone, before counting anything you eat.
For most healthy people, a gallon spread throughout the day is manageable. But drinking large amounts quickly can overwhelm your kidneys’ ability to excrete the excess, causing sodium levels in your blood to drop dangerously low. This condition, called hyponatremia, can be life-threatening. If you’re smaller in stature, not sweating heavily, or have kidney issues, forcing a full gallon daily for 75 straight days is worth discussing with a doctor first.
The Risk of 75 Days Without Rest
Two workouts a day, every day, for 75 consecutive days means 150 total sessions with zero recovery days built in. Standard exercise guidance recommends at least one full rest day per week. Skipping recovery consistently can lead to overtraining syndrome, which shows up as persistent fatigue, mood swings, irritability, trouble sleeping, frequent colds, and a plateau or decline in performance. Overuse injuries to joints, tendons, and muscles become increasingly likely the longer you go without a break.
The severity depends on what you choose as your workouts. Walking for 45 minutes is very different from running or heavy lifting. People who select lower-intensity options for at least some sessions tend to fare much better than those who treat every workout like a high-intensity training day. Still, even with smart programming, 75 days of twice-daily exercise without a single rest day exceeds what most sports medicine professionals would recommend.
The All-or-Nothing Diet Approach
75 Hard lets you pick any nutrition plan you want, which is one of its more flexible elements. The catch is zero deviation for 75 days. No cheat meals, no exceptions. Research from Duke University School of Medicine highlights a tension in this approach: while structure and consistency are genuinely helpful for building better eating habits, labeling any deviation as failure can fuel guilt, shame, and the kind of restrict-then-binge cycle that mirrors disordered eating patterns.
The restart penalty amplifies this. If you eat something off-plan on day 50 and have to go back to day one, the psychological blow can trigger exactly the kind of overcorrection (extreme restriction or punishing exercise) that nutrition researchers flag as harmful. Planned flexibility in a diet, where occasional indulgences are built in rather than forbidden, tends to produce better long-term outcomes because it reinforces the idea that you don’t need perfection. You need consistency.
75 Soft: The Less Rigid Alternative
For people drawn to the structure of 75 Hard but put off by its rigidity, 75 Soft has gained traction as a more sustainable option. It keeps the core concepts (daily exercise, better nutrition, hydration, reading) but removes the restart penalty entirely. If you miss a day, you pick up where you left off instead of going back to zero. Workout requirements are also scaled down, and there’s more room for personal judgment on what counts.
Cleveland Clinic physicians have specifically recommended 75 Soft over 75 Hard for most people, noting that the original challenge “puts a lot of pressure on overhauling different areas of your life” simultaneously and that the restart rule makes the whole endeavor increasingly difficult to sustain. The softer version still builds accountability and discipline. It just doesn’t treat a single imperfect day as total failure.
Who 75 Hard Works Best For
75 Hard tends to resonate most with people who already have a baseline fitness level and thrive under rigid structure. If you’ve been exercising regularly, have a healthy relationship with food, and want a defined challenge with clear boundaries, the program can serve as a focused period of discipline. The reading and photo components add a mental and reflective layer that goes beyond typical fitness challenges.
Where it gets risky is when beginners, people recovering from disordered eating, or anyone dealing with chronic injuries jumps in without modification. The no-modification philosophy is central to Frisella’s message, but your body doesn’t care about motivational frameworks. Ninety minutes of daily exercise with no rest days, combined with rigid dietary rules and a punishment-based restart system, is a significant physical and psychological load. Knowing that going in, and being honest about whether it fits your current situation, matters more than completing any arbitrary number of days.
