Almost everything written about fitness assumes a particular life.It assumes you finish work at a predictable hour. It assumes evenings are broadly yours. It assumes a disposable income that stretches to a membership, and probably a car to get there, and a home with somewhere you could put a bench if you wanted to. It assumes you sleep at night, in one block, on a schedule you control. It assumes nobody else’s body is your responsibility.
For a great many people, none of that is true. Nurses and paramedics and warehouse staff and drivers and hospitality workers don’t have evenings. People on zero-hours contracts don’t know next week. Carers don’t have an hour they can guarantee. Single parents can’t leave the house at seven. Someone working two jobs isn’t short of motivation; they’re short of hours, and no amount of habit-stacking advice fixes that.
And the advice, delivered from inside the template, lands as an accusation. It says: this is simple, just do it consistently. Which quietly implies that if you haven’t, the problem is you.
So this is an attempt to write the other article. Not a stripped-down version of the normal one, but a genuinely different set of assumptions.
Three different problems that look the same
The first thing worth doing is working out which constraint you’re actually up against, because they have completely different solutions and people frequently treat the wrong one.
Time poverty is having too few hours. The solution is short sessions and eliminating travel time. Almost nothing else matters.
Money poverty is not being able to pay for access. The solution is knowing what’s genuinely free, which is more than most people realise.Energy poverty is the hardest and least discussed. It’s having hours that technically exist but arriving at them so depleted that using them is impossible. Shift workers and carers usually have this one, and it doesn’t respond to time-management advice at all, because time was never the binding constraint.
Most people in difficult circumstances have some combination, but usually one dominates. Naming it helps, because “I have no time” and “I have time but I’m destroyed” are different problems and only one of them is solved by a twenty-minute workout.
If the problem is time
The single biggest thing you can do is delete the commute to exercise.For most gym-goers, the actual session is maybe forty minutes and the total cost is ninety. Changing, travelling, parking, waiting for equipment, travelling back. If time is your binding constraint, train at home — not because home training is better, but because it converts a ninety-minute commitment into a twenty-minute one, and twenty minutes exists in almost any life.
You need very little. A pair of adjustable dumbbells or a couple of kettlebells will cover essentially everything, and second-hand ones are widely available because January purchases get resold every spring. Resistance bands cost almost nothing and will genuinely take a beginner a long way. A floor is sufficient for a great deal.
Then compress. Do a small number of movements that cover a lot of ground — a squat or lunge, a push, a pull, a hinge — and move between them without long rests. Twenty minutes done that way is a real session, and the research on shorter, harder training is much more encouraging than the standard advice implies.
The other move is stacking movement onto things already happening. Walking part of a commute. Stairs. Carrying shopping in one trip rather than two, deliberately. These feel like nothing and they aren’t — accumulated daily movement matters more than most single sessions, and it costs no additional time at all.
If the problem is money
More is free than people think.Walking is free and remains, for general health, one of the most effective things available. Parks are free. A great many local authorities have installed outdoor gym equipment in parks, and it’s usually empty. Council leisure centres are frequently much cheaper than commercial gyms, and many run concessionary rates that are not well advertised — it’s worth asking directly rather than assuming.
Bodyweight training is free and genuinely effective for a long time. Press-ups, squats, lunges, rows using a table edge, planks. The limiting factor eventually is load, but “eventually” is a long way off for most people, and there are progressions — one-leg variations, slower tempos, harder angles — that extend it considerably.
Second-hand equipment is abundant and cheap. Local selling pages are full of barely used kit at a fraction of retail.Running is nearly free, though decent shoes aren’t, and that’s the one place I’d tell you to spend. Parkrun and its equivalents are free, weekly, and unusually welcoming — they’re one of the genuinely good things to have emerged in the last twenty years.
What isn’t necessary: supplements, apps, programmes, memberships, branded clothing, wearables. None of that is a prerequisite for anything, and the industry’s central financial trick is convincing people that access requires purchase. If the problem is shift work
This deserves its own section because it’s a genuinely hard problem and the standard advice is nearly useless for it.
The first thing to say is that sleep comes before training. Shift work already disrupts circadian rhythm in ways that have real physiological costs, and sacrificing sleep to train is a bad trade that will make everything worse. If you’re choosing between an hour of exercise and an hour of sleep after a run of nights, take the sleep. That’s not a compromise; that’s the correct answer.
Beyond that, a few things that shift workers I know have found workable:
Don’t train hard immediately after a night shift. Your capacity is reduced, your injury risk is up, and it interferes with the sleep you urgently need. Light movement — a walk in daylight — is a different matter and often actively helps you sleep afterwards.
Anchor to the shift, not the clock. “Every Tuesday at six” doesn’t work when your week rotates. What can work is a rule attached to the pattern: first day off, always. Before every late shift. That gives you a schedule that survives a rota.
Aim for two solid sessions, not four. With an irregular pattern, four sessions a week is a plan that will break and then be abandoned. Two is achievable in almost any rota and is enough to make real progress.
Get daylight when you can. For circadian reasons this is doing more for you than most people realise, and combining it with a walk gets you both at once.
Accept that some weeks are write-offs. A brutal run of shifts is not the week to be disciplined. Do nothing, recover, and pick it up on the other side. The people who last are the ones who don’t treat a bad fortnight as a collapse.
If the problem is energy
The counterintuitive thing, and I want to be careful with it, is that light movement often restores energy rather than spending it.
Not hard training — hard training when you’re already depleted is a genuine mistake and one that shift workers and new parents make constantly. But a twenty-minute walk when you’re flat generally leaves you better than it found you, not worse. Most people have experienced this and still don’t quite believe it, because it violates the intuition that energy is a fixed tank you draw from.
So when you’re exhausted, the useful question isn’t “can I face a session?” It’s “what’s the lightest version of movement I could do?” Usually the answer is a walk, and usually the walk helps.
The other thing worth saying to anyone in this category: rest genuinely is the right call sometimes. Not as a failure. If you’re caring for someone, or working two jobs, or in the newborn phase, there are periods where maintaining anything at all is the win and progress isn’t available. Recognising that is not giving up — it’s accurate, and it prevents the guilt spiral that ends with people abandoning the whole thing.
Redefining what counts
The most damaging import from the standard template is the idea of what a session is.
If a session means an hour at a gym, then a person with fifteen minutes has nothing. If a session means “I moved deliberately for a while,” then that person has something, and something is what compounds.
Fifteen minutes counts. Ten counts. Walking the long way counts. Three sets of press-ups while the pasta boils counts. This isn’t a consolation prize — a genuinely consistent ten minutes a day is meaningfully better for you than a heroic hour you manage twice in a good month.
The template’s other export is the all-or-nothing structure, which is disastrous for irregular lives. If the plan is four sessions and you get two, that reads as failure, and failure repeated for six weeks ends in quitting. Whereas if the plan is “do something most days, some of it hard, adjusted to what the week allows,” there’s no failure state — there are just weeks where less happened.
For anyone whose life is unpredictable, that framing isn’t a lowering of standards. It’s the only one that survives.
The part that’s actually unfair
I’ll end honestly: some of this is not an individual problem and I don’t want to pretend otherwise.
Activity levels track income, working hours and neighbourhood in ways that no amount of personal effort fully explains. If you work nights, live somewhere without safe walking routes, and have no spare hours or money, you’re facing something structural — and being told it’s about discipline is both wrong and insulting.
But within whatever constraints you’ve actually got, there’s usually more available than the template suggests, and it’s almost never the thing being sold. It’s walking, and a pair of second-hand dumbbells, and twenty minutes on the days that allow twenty minutes, and not treating the weeks that don’t as evidence about your character.
The advice was written by people whose lives were regular. Yours isn’t. That’s a difference in circumstances, not in willpower, and the version that fits you is smaller, cheaper and more forgiving than anything you’ve been reading.
