No time to exercise? How to fit it in anyway

If you have no time to exercise, stop hunting for a free hour and start collecting minutes. The WHO's 2020 guidelines dropped the rule that activity only counts in bouts of 10 minutes or more, so a fast walk to the bus, three flights of stairs and a 10-minute workout before dinner all count. Find the minutes in your screen-time report, make your workouts short enough to survive a bad day, and put them in your calendar like meetings.

"No time" is the most respectable excuse ever invented. It makes you sound busy and important, and sometimes it's completely true. Other times it's a polite way of saying "not a priority right now." The fastest way to know which one you're dealing with is to check.

Audit the excuse first

Start with the boring data. In the US government's American Time Use Survey for 2025, people aged 15 and over spent an average of 2.6 hours a day watching TV, about half of their 5.2 hours of daily leisure. Sports, exercise and recreation got about 20 minutes.

Now look at your own numbers, because your phone has been keeping receipts. On an iPhone it's Screen Time in Settings; on Android, Digital Wellbeing. Check the weekly total and the hours when you scroll the most.

Skip the guilt. You're looking for two or three 20-minute blocks that already exist and are currently being spent watching strangers renovate kitchens. If the phone is where your evenings disappear, our guide on how to stop scrolling has the fixes.

And to be fair: some schedules really are full. Two jobs, caring for kids or parents, night shifts. If that's you, nothing below is a lecture. Short bouts are the whole strategy, and they work.

Every minute counts now, officially

The 2010 version of the WHO guidelines said aerobic activity had to come in bouts of at least 10 minutes to count. The 2020 guidelines removed that requirement and put it plainly: doing some physical activity is better than doing none. The US guidelines made the same change in their 2018 edition.

The research behind that shift keeps getting more interesting. A 2022 study in Nature Medicine, led by Emmanuel Stamatakis, looked at 25,241 non-exercisers in the UK Biobank who wore activity trackers. It focused on what the authors called vigorous intermittent lifestyle physical activity: bursts of a minute or two built into daily life, like rushing up the stairs or power-walking through errands. Over about seven years, people who had around three of those bursts a day had a 38 to 40% lower risk of death from any cause and from cancer, and a 48 to 49% lower risk of death from cardiovascular disease, than people who had none.

It's an observational study, so it shows an association, not proof that the bursts caused the difference. But it's a very good reason to take the stairs like you're late for something.

Short workouts that actually do something

Short doesn't mean pointless. Two small studies from Martin Gibala's lab at McMaster University show how little time can still count:

• Stair "snacks." In a 2019 study by Jenkins and colleagues, inactive young adults climbed three flights of stairs (60 steps) at a vigorous pace three times a day, with one to four hours between climbs, three days a week. After six weeks their cardiorespiratory fitness had improved compared with a group that didn't train. The gain was modest, and so was the time it took.
• Sprint intervals. In a 2016 study by Gillen and colleagues, inactive men did 10-minute sessions on a bike with three 20-second all-out sprints, three times a week for 12 weeks. Their fitness (peak oxygen uptake) rose 19%, the same as a group that cycled at a moderate pace for 45 minutes per session. The groups were small, and the authors note that all-out sprints take a lot of motivation and aren't for everyone.

If you have a heart condition, chest pain when you exert yourself or haven't exercised in years, talk to a doctor before going all-out on anything.

For strength, you don't need equipment either. A 10-minute circuit at home:

1. Squats
2. Push-ups (against a counter or a wall if the floor is too much for now)
3. Reverse lunges
4. Rows with a loaded backpack
5. Plank

Do 40 seconds of each with 20 seconds of rest, twice through. Done with real effort on two days a week, it's a legitimate start on the WHO's two strength days.

Steal minutes from things you already do

You don't have to find new time if you can upgrade the time you already spend:

• The commute. Walk or bike part of it, or get off a stop early. Ten minutes each way is 100 minutes over a work week.
• The stairs. Always, and at a pace that makes you breathe.
• Phone calls. Take the ones that don't need a screen on foot.
• Waiting. The coffee maker, the microwave, a slow loading screen: squats until it's done.
• One episode, one workout. Pair the show you love with the bike or the mat; it's called temptation bundling, and our guide on how to get motivated to work out explains why it works.
• Kids' practice. Walk laps around the field instead of watching from the bleachers.

Book it like a meeting

Minutes in your day are good. Sessions in your calendar are better, because what's on the calendar happens and what's "whenever I get a chance" doesn't.

• Block two or three slots of 20 to 30 minutes this week. Give them a name and a time.
• If something collides with a block, you move the block. You don't delete it.
• Attach it to something that already happens every day: "after I drop the kids off, I walk for 20 minutes." That's habit stacking, and it means you don't have to remember.
• Have a backup. If the 30-minute block dies, the 10-minute circuit happens the same day.

If you want something to nag you, Toxic Coach's goals do exactly that: the reminders escalate from mild to savage as the deadline gets closer, and you can tell your coach your excuse.

The no-time excuses, decoded

• "I don't have an hour." Nobody asked for an hour.
• "I'll start when things calm down at work." In the entire history of work, things have never calmed down.
• "If I can't do a full workout, what's the point?" The WHO literally deleted that rule.
• "I'm too tired after work." Then move it before work, or make it ten minutes. And if you're exhausted all the time, no matter how you sleep, that's worth a visit to the doctor, not more willpower.
• "I'll make up for it on the weekend." Weekend sessions count. Just don't let them become the reason the weekday minutes never happen.

Today's tiny assignment

Open your screen-time report and find two 20-minute blocks for this week. Put them in your calendar with a name. Then do the 10-minute circuit today, before you can talk yourself out of it. When you're ready to plan a full week, read how many days a week to work out.
