75 Soft and 75 Hard share a number, a 75-day length, and a promise of change — and that's roughly where the similarities end. One is a mental-toughness test with zero tolerance for slip-ups; the other is a habit-building program designed so real life doesn't knock you out of it. This comparison walks through both rule sets side by side, explains the four differences that actually matter, and gives you an honest way to decide which one fits your life right now.
The quick answer
Choose 75 Hard if you want an extreme mental-toughness test, already train regularly, and have the schedule for two workouts a day. Choose 75 Soft if your goal is lasting habits — daily movement, better eating, more reading — with rules forgiving enough that you'll actually reach day 75. Most beginners, busy parents, and anyone returning to fitness after a break do better on 75 Soft.
What is 75 Hard?
75 Hard was created in 2019 by entrepreneur Andy Frisella, who describes it not as a fitness challenge but as a “transformative mental toughness program.” For 75 consecutive days you must:
- Complete two 45-minute workouts every day, one of them outdoors — regardless of weather.
- Follow a diet of your choice with zero cheat meals and no alcohol.
- Drink a gallon of water (about 3.8 litres) daily.
- Read 10 pages of a non-fiction book (audiobooks don't count).
- Take a daily progress photo.
The defining rule sits on top of all five: miss any task, even once, and you start over at day one. That all-or-nothing structure is intentional — the program is about proving to yourself that you can do hard things without compromise. It's also why so many attempts end in week two or three.
What is 75 Soft?
75 Soft emerged on social media as a response to 75 Hard's intensity — same 75-day commitment, redesigned for sustainability. The four daily rules are:
- One 45-minute workout a day, any type, with one active-recovery day per week.
- Eat well, with one cheat meal per week allowed.
- Drink 3 litres of water (about 100 oz) daily.
- Read 10 pages of any book.
There's no daily photo and no outdoor requirement — and while the strict version still sends you back to day one after a miss, many people run 75 Soft in a forgiving way and continue instead. If you want the complete breakdown of each rule and how to set them up, our full 75 Soft Challenge rules guide covers everything.
The rules, side by side
| Rule | 75 Hard | 75 Soft |
|---|---|---|
| Workouts | 2 × 45 min daily, one outdoors | 1 × 45 min daily, one recovery day/week |
| Diet | Strict, zero cheat meals | Balanced, one cheat meal/week |
| Alcohol | Banned | Not banned (moderation) |
| Water | 1 gallon (~3.8 L) | 3 litres (~100 oz) |
| Reading | 10 pages non-fiction | 10 pages, any book |
| Progress photo | Required daily | Not required |
| Miss a task? | Restart at day 1, always | Your call: strict restart, or log it and continue |
The 4 differences that matter most
1. One workout vs two
Two 45-minute workouts a day is 10.5 hours of training a week — before counting travel, showers, and getting outdoors in January. For athletes in a focused block, that can work. For someone with a full-time job, kids, or a beginner's fitness base, it's the single most common reason 75 Hard attempts collapse. One daily workout is still far more than most people do, and it leaves room for the rest of your life.
2. The restart rule
This one is more nuanced than most articles admit. 75 Hard's restart rule is official and absolute: miss anything and you go back to day one, even from day 74. 75 Soft has no official rulebook — the strict reading also restarts you, but the challenge's culture leans the other way: log the miss, continue the next day, and let consistency beat perfection. What matters is deciding your rule before day 1 so a slip doesn't turn into a quiet exit. If you've ever abandoned a diet because of one bad weekend, choose the forgiving version — getting back on track quickly builds habits; all-or-nothing resets tend to end in quitting entirely.
3. Food flexibility
Zero cheat meals for 75 days means birthdays, anniversaries, and every dinner out become tests of willpower. 75 Soft's weekly cheat meal is a pressure valve: you can say yes to the birthday cake on Saturday and be right back on plan at the next meal.

4. What happens after day 75
75 Hard ends with a finish line; many finishers describe swinging back to old routines once the pressure lifts. 75 Soft's rules are mild enough that day 76 can look a lot like day 75 — that's the point. You're not white-knuckling through an extreme program; you're practising a routine you could keep for years.
Which challenge should you do?
Pick 75 Hard if: you already train consistently, you have real schedule flexibility, you respond well to all-or-nothing stakes, and the mental-toughness aspect — not fitness — is your main goal. It is a legitimate, difficult program, and finishing it is a genuine achievement.
Pick 75 Soft if: you're building (or rebuilding) a fitness base, your schedule is unpredictable, past all-or-nothing attempts have ended in burnout, or your actual goal is habits that outlast the challenge. It's not the easy way out — 75 consecutive days of workouts, water, reading, and intentional eating is a real commitment — it's the version engineered so you finish.
And be honest about expectations either way: 75 days changes routines and fitness meaningfully, but it isn't a body transformation guarantee. We wrote about what results you can realistically expect from 75 Soft without the before/after hype.
