# 75 Hard Alternatives: 6 Challenges That Survive a Real Life

> Six real 75 Hard alternatives compared: 75 Soft, 75 Medium, 75 Sustainable, 57 Chill and more, with the rules, the trade-offs, and how to pick one.

Canonical: https://habithuddle.com/blog/75-hard-alternative

The best 75 Hard alternative is the one that keeps the rule you actually needed and drops the rule that broke you. For most people that means keeping the 75 day container and the daily non-negotiable, and dropping the clause that sends you back to day 1 for a single miss. 75 Soft, 75 Medium, 75 Sustainable, 57 Chill and a plain 30 day challenge all do exactly that, in different ways.

This guide covers six alternatives with their real rules, who each one fits, and where each one falls short. It also covers the part almost every "gentler challenge" article skips: what to change so you finish this one, after quitting the last one on day 12.

## What the 75 Hard rules actually are

75 Hard is a mental toughness program created by Andy Frisella, not a fitness plan. The daily requirements are: follow a diet of your choice with no cheat meals and no alcohol, complete two 45 minute workouts with one of them outdoors, drink a gallon of water, read 10 pages of non-fiction, and take a progress photo. You do all five, every day, for 75 days. Miss any single item and you restart at day 1.

Every alternative below is a negotiation with one or more of those six rules. Knowing which rule beat you tells you which alternative to pick, so it is worth being specific with yourself before you scroll. Was it the two workouts, the alcohol clause, the outdoor workout in February, or the restart?

## The rule that breaks people is the reset, not the workouts

![Illustration of a habit calendar with a long chain of completed days and one missed day resetting the count to zero](https://habithuddle.com/storage/seo/legacy/f5e9878941b4695f175ee5b6e6dc61858cac0493.jpg)

The all-or-nothing restart is the part of 75 Hard with the weakest evidence behind it. In the most cited real-world study of habit formation, Lally and colleagues tracked 96 people forming a new daily habit and found that automaticity took a median of 66 days, and that [missing a single opportunity did not measurably damage the habit formation process](https://doi.org/10.1002/ejsp.674). One missed day is noise. Treating it as a total failure is a design choice, not a finding.

That design choice does real work for 75 Hard. It is what makes finishing feel like status, and the people who thrive on it are not wrong to love it. But it also creates the classic all-or-nothing spiral: you miss the second workout on a Tuesday, you are technically out, so the rest of the week stops mattering, and by Sunday the whole project is gone.

If you have started 75 Hard more than once and never reached day 30, the fix is almost certainly not more discipline. It is a challenge whose worst possible day is survivable.

## The 6 best 75 Hard alternatives at a glance

| Challenge | Length | Daily requirement | Miss a day? | Best for |
|---|---|---|---|---|
| 75 Soft | 75 days | 45 min exercise, 3 L water, 10 pages, eat well, drink only socially | No official reset | People who want structure without the extremes |
| 75 Medium | 75 days | A lighter set you define, usually one workout and 2 to 3 habits | No reset, resume next day | People who want 75 Hard's shape at 60% intensity |
| 75 Sustainable | 75 days | Rules you write from what already makes you feel good | No reset | People who know their own levers |
| 57 Chill | 57 days | A floor of about 6 minutes, ceiling optional | Floor keeps you going, no reset | People who quit challenges alone and want a group |
| 30 day challenge | 30 days | One habit, one action | Depends on your rule | First-time finishers who need a win |
| Modified 75 Hard | 75 days | The original five, minus your written amendment | Your call, decided in advance | People who love the original and want to finish it |

## 1. 75 Soft: the flexible version everyone starts with

75 Soft is the most popular 75 Hard alternative and the one most likely to already have a community around it. The commonly used rules are: exercise 45 minutes a day with one day per week as active recovery, drink three litres of water, read 10 pages of any book, and eat well while restricting alcohol to social occasions.

Two changes carry all the weight. First, one workout instead of two, with a built-in recovery day, which turns the schedule from a second job back into a routine. Second, "any book" instead of self-development non-fiction, which quietly removes the most common reason people fall behind on the reading rule. Women's Health's first-person account of the challenge describes it as [a routine reset rather than an entire life change](https://www.womenshealthmag.com/uk/fitness/a44489358/75-soft-challenge/), which is a fair summary.

**Good fit:** you liked the idea of 75 Hard and want the same 75 day arc at an intensity you can hold while employed.

**Trade-off:** 75 Soft has no official rulebook and no restart clause, which means nothing external stops you from quietly downgrading it week by week until it is just a vague intention. You have to supply the enforcement yourself.

## 2. 75 Medium: same 75 days, rules you negotiate

75 Medium sits between the two and is defined by the person doing it, not by a rulebook. The usual shape keeps the 75 day container and a small set of daily non-negotiables, typically one workout, a water target, some reading or journaling, and a food rule stated as an addition rather than a restriction, for example "eat protein and vegetables at every meal" instead of "no cheats."

The reason this variant spread is emotional rather than physiological. The framing is consistency instead of perfection, and challenge instead of punishment. For people whose relationship with fitness challenges includes a history of over-exercising or restriction, that reframing is the entire point, and several of the popular 75 Medium write-ups say so directly.

**Good fit:** you want the discipline of a long challenge without a rule set that can be turned against you on a bad mental health week.

**Trade-off:** because you write the rules, you can write them too easy, and 75 days of "too easy" leaves you at day 75 without much to show. Set the bar where a bad day is survivable and a normal day takes real effort.

## 3. 75 Sustainable: write your own rules from what already works

75 Sustainable inverts the usual approach: instead of adopting someone else's rules, you list the things that reliably make you feel good and turn those into the challenge. The bloggers who popularised it describe starting from the sentence "I feel best when ___" and filling in the blanks, then keeping the 75 day frame.

A typical set ends up mixed rather than fitness-only: a 30 minute walk or workout, a step goal, 30 minutes of time to yourself, a protein target, 15 minutes of tidying, some time off your phone. That mix is the strength of the format. It is also the closest of these challenges to what habit research actually supports, because each item is small, specific, and attached to a daily cue.

**Good fit:** you have done challenges before, you know which levers move your mood, and you do not need a stranger's rulebook to feel legitimate.

**Trade-off:** it is the hardest one to explain to other people, which matters more than it sounds. A challenge nobody else recognises is a challenge nobody else will ask you about.

## 4. 57 Chill: a floor you can hit on your worst day

Full disclosure before anything else: [57 Chill](https://habithuddle.com/57-chill) is our challenge, built by us, so read the reasoning rather than the ranking. It exists because of one pattern we kept seeing, which is people restarting 75 Hard for the third time and concluding that they are the problem.

57 Chill flips 75 Hard's number and its failure rule. It runs 57 days, and every day has two levels. The Floor is roughly six minutes: move for five minutes, read one page, drink one glass of water. The Ceiling is the entire Frisella day, two workouts with one outside, strict diet, four litres of water, 10 pages, progress photo. Step on the Floor and the day counts. Burst through the Ceiling when you have it in you, and it is logged as the flex it is. There is no reset, because the Floor is designed to be beatable while sick, travelling, or holding a newborn.

The second difference is that you do it inside a huddle, a small group that sees every checkin, so quitting is something other people notice rather than a private decision made at 11pm. The challenge, the huddle and the habit are free. Free accounts get one starter streak freeze; ongoing freezes and flex checkins are perks of paid Habit Huddle Pro plans, and 57 Chill does not require them.

**Good fit:** you have quit challenges alone before and suspect the missing ingredient is other people, not a better rulebook.

**Trade-off:** it needs an app and at least a couple of other humans, so it is more setup than writing four rules on a sticky note. And if what you actually wanted was the punishing version, this is not it. 75 Hard is a real program with real fans, and we are not affiliated with it; if the brutality is the appeal, go and do that one properly.

## 5. A 30 day challenge: the shortest useful container

A 30 day challenge beats a 75 day challenge for anyone who has never finished either. Finishing is a skill, and 30 days is long enough to build a genuine routine while short enough that you can see the end from the start, which matters enormously in weeks two and three when novelty has worn off and results have not arrived.

Keep it to one habit and one action, defined so precisely that there is no daily negotiation: "20 minutes of walking before 9am" rather than "exercise more." The internet version of this idea, No Zero Days, adds the only rule that matters on the bad days: do the smallest possible version rather than nothing.

**Good fit:** you have a stack of abandoned 75 day attempts and need one completed challenge before you attempt another long one. There are [more group challenge ideas here](https://habithuddle.com/blog/group-fitness-challenge-ideas) if you want to run one with other people.

**Trade-off:** 30 days is usually short of the median 66 days that Lally's participants needed for automaticity, so plan the day 31 continuation before day 30 arrives, or the habit goes with the challenge.

## 6. Modified 75 Hard: keep the rules, write the amendment first

Modified 75 Hard is the honest version of what most people end up doing anyway. Keep the original five tasks, then decide in advance, in writing, exactly which one you are amending and what the amendment is: one workout on weekdays and two on weekends, or three litres of water instead of a gallon, or a rest day every seventh day.

The rule that makes this work is that the amendment is written down before day 1 and never edited mid-challenge. An amendment decided in advance is a design decision. An amendment decided at 9pm on day 22 is quitting with extra steps, and you will know the difference.

**Good fit:** you genuinely like the original program and one specific rule is incompatible with your life, for example shift work, an injury, or pregnancy.

**Trade-off:** you do not get to say you completed 75 Hard, and some of the community will tell you so. Decide now whether that bothers you.

## Whichever one you pick, do not do it alone

![Illustration of a small diverse group of friends celebrating each other's daily checkins on their phones](https://habithuddle.com/storage/seo/legacy/93c0384d3b04697b51a357bd4a5fd65f4df20fc1.jpg)

Adding other people to a challenge measurably changes the outcome. In the STEP UP randomized clinical trial, 602 adults were assigned to gamified physical activity programs with different social framings. All three social arms beat the control group during the 24 week intervention, and [the competition arm gained about 920 steps per day over control](https://pubmed.ncbi.nlm.nih.gov/31498375/). More striking is what happened after the program ended: only the competition arm was still significantly ahead at follow-up.

Solo challenges have exactly one enforcement mechanism, which is how you feel on the day. That mechanism is unreliable in week three, in February, and after a bad night of sleep. A group is the only thing that keeps working on the days you do not feel like it, because the cost of quitting is no longer private.

This is what Habit Huddle is built for. You put your challenge habit in a huddle with a few friends, everyone sees each other's daily checkins, and the group's Checkin Chain grows by one link for every member who checks in that day, so a quiet day is visible immediately. It is free to run a challenge this way with one active habit. It is genuinely worse than a solo app if what you want is private tracking with nobody watching, and it needs at least one other person to be worth anything. If that sounds right, [start a huddle for your challenge](https://habithuddle.com/app) and run whichever alternative above you picked inside it.

## How to choose in 60 seconds

![Illustration of a person at a fork in a path choosing between several different challenge routes](https://habithuddle.com/storage/seo/legacy/368a924e21a04abd0aa151d39d193ede6bc95486.jpg)

Pick by the rule that beat you last time.

- **The two workouts beat you:** 75 Soft.
- **The diet and alcohol rules beat you:** 75 Medium, with the food rule written as an addition.
- **Somebody else's rules never fit your life:** 75 Sustainable.
- **The restart beat you, repeatedly:** 57 Chill, or any challenge with a defined minimum version.
- **You have never finished any of them:** a 30 day challenge with one habit.
- **Nothing beat you, one rule is just impossible right now:** modified 75 Hard, amendment in writing.

Then add the multiplier that none of these rulebooks include: tell at least one person, and make your daily result visible to them.

## Frequently asked questions

**What is the easiest 75 Hard alternative?**
75 Soft is the easiest of the widely recognised variants, because it drops one of the two daily workouts, adds a weekly active recovery day, and allows any book instead of non-fiction. If you want something easier still, a 30 day challenge with a single habit is a better starting point than a diluted 75 day program.

**Is there a 75 Hard alternative that does not make you restart?**
Yes, and it is the main reason people switch. 75 Soft, 75 Medium and 75 Sustainable have no restart clause at all. 57 Chill goes further by defining a daily minimum small enough to hit on your worst day, so a hard day produces a small checkin instead of a broken challenge.

**Do these alternatives actually work?**
They work in the sense that most people who pick a realistic variant finish it, and finishing is what builds the underlying skill. Research on habit formation puts the median time to automaticity at around 66 days, so any 75 day container is a reasonable length. What predicts finishing is not the intensity of the rules, it is whether your worst day has a survivable version and whether anyone else is watching.

**Can I do a 75 Hard alternative with friends?**
Yes, and the evidence favours it. The STEP UP trial found social and competitive framings increased daily activity over 24 weeks, with the competitive group the only one still ahead months later. Practically, that means agreeing on the same rule set, checking in daily somewhere everyone can see, and keeping the group small enough that an absence is noticeable.

**How long should a habit challenge be?**
Long enough to pass the novelty phase, short enough that you can picture the end. Thirty days is the right length for your first completed challenge, 75 days for people who have finished one before, and 57 days sits between them on purpose. What matters far more than the number is that the daily requirement has a minimum version you can hit at your worst.
