HabitKeepWhat Is 75 Soft? The Challenge You Can Actually Finish
75 Hard has a reputation for a reason. Five daily tasks, seventy-five consecutive days, and a rule that miss anything at all — one task, one day — and you start again from zero. It’s a genuine mental toughness programme and plenty of people finish it.
Plenty more don’t, and quit somewhere around day nineteen after a work trip, an illness, or a single evening that got away from them. 75 Soft exists for exactly that gap.
The rules
There’s no single official version, but the widely used one is:
- Exercise for 45 minutes a day, with one day per week allowed to be active recovery — a walk, stretching, light mobility work.
- Eat well and only drink alcohol on social occasions, rather than a rigid diet with no deviation.
- Drink 3 litres of water a day.
- Read 10 pages of any book. Fiction counts.
Seventy-five days. And critically: if you miss a day, you carry on the next day. No restart.
What changed, and why it matters
Set the two side by side and the differences are pointed:
| 75 Hard | 75 Soft | |
|---|---|---|
| Workouts | Two 45-min sessions, one outdoors in any weather | One 45-min session, weekly rest day allowed |
| Diet | Strict plan, zero cheat meals, no alcohol | Eat well, alcohol on social occasions |
| Water | 1 gallon (3.8 L) | 3 L |
| Reading | 10 pages of non-fiction | 10 pages of anything |
| Progress photo | Daily, required | Optional |
| Missing a day | Restart from day 1 | Carry on tomorrow |
The restart rule is the whole argument. It’s defended as the point of the exercise — the discipline is the no-exceptions clause. That’s a coherent position for a mental toughness challenge.
It’s a bad position for building lasting habits, for a specific reason: the restart makes a missed day catastrophic, and catastrophic failures make people quit entirely. Someone who misses day 40 of 75 Hard doesn’t usually restart on day 41. They stop. Two months of real work evaporates because of one evening.
75 Soft’s version — miss it, resume tomorrow — produces a worse day and an identical week. That’s the whole trick, and it’s supported by everything we know about behaviour change: consistency over time beats intensity, and the single strongest predictor of long-term adherence is how quickly you resume after a lapse.
Who each one suits
75 Hard makes sense if you have a stable, controllable schedule, you’ve done structured programmes before, you respond well to absolute rules, and you specifically want the mental challenge rather than the fitness outcome.
75 Soft makes sense if you have kids, shift work, travel, a chronic condition, an unpredictable job, or a history of all-or-nothing cycles where one slip ends the whole attempt. It also makes sense as a first attempt before considering the harder version.
Choosing the gentler one isn’t a lack of discipline. Finishing 75 Soft beats abandoning 75 Hard on day twelve by every measure that matters.
Setting it up so it actually runs
Four tasks a day for seventy-five days is 300 completions. Tracking that in your head fails within a week, and tracking it on paper fails the first time you’re away from the paper.
A sensible setup:
One habit per rule, tracked the way it’s actually measured. Exercise is a timer — start it, do the session, and the log happens by itself. Water is a count, ticking up glass by glass rather than one all-or-nothing check at midnight. Reading is a simple check-off. Keeping the tracking method matched to the task removes the friction that kills tracking.
Let Apple Health do the exercise one. If you log workouts on a watch, or you’re counting steps and active minutes anyway, that habit can fill itself in. A habit that completes without you opening an app is a habit you won’t forget.
Reminders at the right time, not all at once. Water spread across the day. Reading in the evening. Exercise when you actually train. A single 9pm notification listing four things you didn’t do is just guilt.
A widget on the home screen. The main reason a task gets missed isn’t unwillingness — it’s not being reminded while there’s still time. Seeing three rings and one gap at 4pm fixes more days than any amount of motivation.
Watch the completion rate, not just the streak. This matters more on 75 Soft than 75 Hard, because the streak isn’t the scoring mechanism any more. What you want to see at day 75 is something like “68 of 75 days on water, 71 on reading.” That’s the real result, and it’s a far more honest picture than a streak counter that resets.
About the missed days
Plan for them now, while you’re calm, because you will have some.
Decide in advance what counts as a legitimate pause — genuine illness, a family emergency, travel where the rules simply aren’t possible. Pause those days deliberately rather than logging them as failures, so your statistics reflect what actually happened. A week off with flu shouldn’t look identical to a week of not bothering.
Then apply the one rule that carries the whole thing: never miss twice. One missed day is noise. Two in a row is where a challenge quietly ends. If you miss Tuesday, Wednesday is non-negotiable — and it doesn’t matter whether Wednesday is a great effort or a bare minimum. It matters that it happened.
HabitKeep handles all of this — timers with Live Activities, counts for water, Apple Health filling in your workouts, 14 widget styles, an Apple Watch app, per-habit reminders, and vacation mode for days that genuinely shouldn’t count against you. The full-year grid at the end of seventy-five days is a surprisingly good motivator on its own.
