“Don’t give up.” “You’ve got this.” “Push through the pain.” These have become standard phrases in fitness and self-improvement, the sort of thing people repeat to themselves at the point where a new routine starts to hurt. They can be useful. They also raise a question worth asking: at what point does pushing through stop being helpful?

The 75 Hard Challenge sits squarely in that territory. It is one of the more visible lifestyle programs of recent years, built around a deliberately uncompromising structure. Five tasks, every day, for 75 days. Miss any part of any one of them and you go back to day one.

For some people that structure is the appeal. For others it raises questions about safety, sustainability and whether the all-or-nothing framing does more harm than good. Here is what the challenge involves and what is worth thinking about before starting it.

What is the 75 Hard Challenge?

The program was created by entrepreneur and podcast host Andy Frisella, who presents it as a mental toughness program rather than a fitness one. The stated aim is building discipline and consistency by requiring people to hold to a difficult routine without exception.

It is not built on a particular training methodology or nutritional framework. The organising idea is the rigidity itself: do not quit, do not negotiate with yourself, finish what you started.

That rigidity is also the main thing to weigh up. A program with no allowance for illness, injury, travel, caring responsibilities or an ordinary bad week is a program most people’s lives will interrupt at some point. Whether restarting from day one after that interruption is motivating or demoralising depends a great deal on the person.

The five daily rules

All five have to be completed every day for 75 days. Falling short on one means starting again from the beginning.

1. Follow a nutrition plan, with no alcohol and no cheat meals

You choose the eating plan. Keto, vegan, paleo, something else — the challenge does not specify. What it specifies is that once chosen, you hold to it exactly:

• No cheat meals
• No alcohol
• No changing plans partway through

Eating patterns people commonly pick include:

• Mediterranean: built around vegetables, fruit, whole grains, fish and poultry, and olive oil and other unsaturated fats.
• Keto: high fat, very low carbohydrate.
• Vegan: entirely plant-based, excluding all animal products.
• Flexitarian: mostly plant-based, with meat and animal products occasionally.
• Paleo: based on meat, fish, vegetables, fruit, nuts and seeds, excluding grains, legumes, dairy and processed foods.
• Pegan: a combination of paleo and vegan approaches, mostly plant-based with some animal products.
• DASH: an eating pattern lower in sodium, with an emphasis on vegetables, fruit and other potassium-rich foods.
• Whole30: a 30-day elimination approach that removes grains, legumes, dairy, sugar and processed foods.

The intent is structure and self-control. Two and a half months of exact adherence is a different proposition from a general intention to eat better, and it is harder than it sounds on paper.

Food is not only fuel. It sits inside social life, family routines, culture and how people manage a difficult day. Removing all flexibility from it at once is a significant change, particularly for someone who has not followed a structured eating plan before, or who is managing a health condition where diet matters.

Speak with your GP or a dietitian before starting any restrictive eating plan, and particularly one this strict. There are less rigid patterns, the Mediterranean approach among them, that more people find they can hold to over time. Rules that bend a little tend to last longer than rules that do not.

2. Two 45-minute workouts a day, one of them outdoors

General health guidance in Australia points to regular moderate activity across the week, in the order of 30 minutes on most days, and there is no shortage of ways to get it. Walking, swimming, weights, a yoga class. What you do matters less than doing something you will keep doing.

The challenge asks for considerably more than that: 90 minutes across two separate sessions, every day, with one of them outside regardless of the weather.

For someone already training daily, that may be demanding but achievable. For a beginner, for anyone with limited mobility or a long-term condition, or for anyone with a full schedule and other people to look after, it is a different story.

The concern is not only the time. Going from little structured exercise to two sessions a day, with no rest days built in, raises the risk of injury. Recovery is an important part of physical training, and 75 consecutive days of exercise can make it harder to build adequate recovery into a routine.

There is a mindset problem too. Framing exercise as something that has to hurt encourages people to work through pain that is telling them something. It can be difficult to distinguish ordinary training discomfort from pain that signals a need to stop or modify an activity. A program built around not stopping may make it harder for some people to respond appropriately to those signals. People returning after time away are particularly prone to misjudging what their body currently handles.

3. Drink around 3.8 litres of water a day

The hydration rule is straightforward: drink roughly a gallon, about 3.8 litres, daily.

Commonly cited adequate intake figures are around 2.7 litres a day for women and 3.7 litres for men. Those numbers refer to total water from all sources, including the water in food, rather than to what you drink, and needs vary with body size, activity, climate and health. The challenge’s target sits above them, and applies as a fixed number to everyone.

There is an upside. Deliberately drinking more water often displaces soft drinks, energy drinks and sweetened coffee, which is a reasonable change on its own. Building the habit of drinking through the day suits some people well.

Thirst is a reasonable guide, though, and a single fixed target is not. On a quiet day, forcing down close to four litres can be uncomfortable and is not obviously useful.

4. Read 10 pages of non-fiction

Ten pages a day, of non-fiction or personal development rather than anything you like the look of.

This is the gentlest of the five and arguably the most sensible. Time reading is time off screens and away from the rest of the day, and after a session of training, tracking meals and counting litres of water, twenty quiet minutes is a reasonable counterweight.

Ten pages is not much in isolation. Ten pages every day, on top of everything else, is more of an ask than it looks if reading is not already part of your routine.

5. Take a daily progress photo

Some people find that daily weigh-ins can be unhelpful, because body weight can move from day to day for reasons that do not necessarily reflect longer-term progress. This rule goes the other way: a full-body photo, every day, for 75 days.

The reasoning is that change is gradual and easier to see across weeks than from one day to the next. For some people that works, and a series of photographs shows something the mirror does not.

For some people, daily photographic scrutiny of their body can contribute to:

• Lower confidence about body image
• Increased focus on appearance
• Greater concern about food, eating or body image

If the photos show what you hoped for, they encourage you. If they do not, the daily reminder of that becomes its own problem, and the effect on how you feel about yourself can outlast the challenge.

Physical change is not linear and it is not fast. Some of the things worth having from 75 days of consistent effort will not appear in a photograph at all.

If tracking your body this way starts to feel distressing, or if food and eating have become a source of ongoing worry, stop and speak to your GP. That is common, it is taken seriously, and there is support available.

Looking for a healthier way forward?

Before committing to something like 75 Hard, it is worth being honest about the fit. What does it ask of you, what does it risk, and does it work alongside your health, your schedule and where your energy is currently at?

Stacking large changes on top of each other simultaneously is demanding physically and mentally, and the failure mode is usually not a dramatic collapse but a quiet abandonment somewhere around week three.

Smaller steps hold better. If mornings are the problem, move your alarm back an hour this week and another hour next week rather than two hours tomorrow. If soft drink is the problem, cutting to one a day is a real change. If you want to train more, start with once a week and add as your body adapts.

And if you miss a day, that is genuinely fine. Restarting from zero is a rule someone invented; it is not a fact about how habits form.

The individual goals inside 75 Hard are all reasonable ones. More water, better food, daily reading, more movement, some structure. None of them require an all-or-nothing framework to be worth doing.

Is there a gentler alternative?

There is a lighter version, also from Frisella, called 75 Soft. It keeps the shape of the original with considerably less pressure:

• Eat well, without the restriction and without banning alcohol outright
• Exercise 45 minutes a day, with one active recovery day each week
• Drink around 3 litres of water a day
• Read 10 pages of any book, not only non-fiction

That version places less emphasis on rigid restrictions and may be easier for some people to fit around their individual circumstances.

Whether it is 75 Soft, a version you build yourself, or no challenge at all, the useful part is being deliberate about how you approach change. Starting, pausing and starting again is not failure. Reshaping a goal so it fits your life is not cheating.

Perfection over 75 consecutive days is a demanding standard and not a particularly meaningful one. What tends to matter more is being able to recover, adapt and carry on when a week does not go the way you planned.
