75 soft vs 75 hard: every difference, honestly compared
Same length, same promise — 75 straight days of keeping your word to yourself — and two completely different philosophies about what happens when you're human. Here's the whole comparison, rule by rule, without pretending either version is magic.
The rules, side by side
| 75 Hard | 75 Soft | |
|---|---|---|
| Workouts | Two × 45 min a day, one must be outdoors — rain, heatwave, whatever | One × 45 min a day, one active-recovery day a week |
| Diet | A strict named diet, zero cheat meals, zero alcohol | Eat well by your own honest definition; alcohol only on social occasions |
| Water | 1 gallon (3.8 L) | 3 litres |
| Reading | 10 pages, non-fiction only | 10 pages, any book |
| Progress photo | Every single day, mandatory | Optional (recommended — day 75 you will thank you) |
| Miss a day? | Restart from day 1 | Continue the next morning |
| The real goal | Mental toughness | Habits that survive contact with your actual life |
The restart rule is the whole argument
Everything else is a matter of degree; this is a matter of philosophy. 75 Hard treats a missed rule as proof you need to start over — which builds an identity ("I'm someone who doesn't negotiate") but also means one 80% day erases eleven perfect ones. That's exactly where most attempts end: not at the gym, but in the shame spiral after the first slip.
75 soft's bet is the opposite: consistency is a batting average, not a perfect game. A bad day costs you a day. It can't cost you the challenge.
Which one should you actually do?
And if 75 soft still feels like a stretch — that's not a character flaw, that's information. Shrink the rules until they survive your worst week, then run. (Our full 75 soft guide covers the rules in detail, plus a free printable checklist.)
Either way: don't do it alone
The quiet truth about both challenges: the finish rate has less to do with hard-vs-soft than with whether anyone's watching. One witness — a friend running theirs beside you, seeing your daily ticks — roughly doubles completion odds. It's the cheapest performance enhancer that exists.
That's what Bloom is built around: your challenge as tap-to-tick daily cards, a streak with a shield for being human, and an accountability partner — your real bestie via an invite link, or an AI one who texts like a friend and notices when you go quiet.
