Exercise ‘Snacks’ Throughout Your Day Have Real Health Benefits, Study Finds
Your fitness tracker might be telling you that you need 10,000 steps, 30 minutes of cardio or even an hour at the gym every day. But what if you could improve your health in just a few minutes a day? A growing body of research suggests you can.
“Exercise snacks” are brief bursts of vigorous exercise, typically lasting one minute or less, scattered throughout your day. Think climbing a few flights of stairs, doing some squats during a work break, or a quick burst of jumping jacks before lunch.
Unlike traditional workouts, these “snacks” aren’t done back-to-back – they’re spread across your waking hours, separated by one to four hours of your regular activities such as working, commuting, or watching TV.

The concept differs from high-intensity interval training (Hiit), where you might do multiple intense bursts of activity within a single 20-minute workout. Exercise snacks are more like grazing throughout the day rather than sitting down for a full meal.
A recent meta-analysis published in the British Journal of Sports Medicine found that in previously sedentary adults, exercise snacks significantly improved cardiorespiratory fitness, a measure of how well your heart and lungs work during physical activity.
The review concluded that these bite-sized workouts delivered meaningful health benefits, with an impressive 83% of participants sticking to their routines for up to three months.
Why exercise snacking works
Around a third of adults worldwide don’t get enough physical activity. When asked why, the answers are almost always the same: no time and no motivation. Exercise snacks tackle both barriers head-on.
In a 2019 study, sedentary young adults were asked to vigorously climb a three-flight stairwell three times per day – with one to four hours of recovery between bouts. Each session also included a brief warm-up of jumping jacks, squats, and lunges.
After six weeks, the stair climbers showed significant improvements in cardiorespiratory fitness compared to a control group – a key marker linked to longevity and reduced cardiovascular disease risk.
What’s particularly striking about exercise snacks is their efficiency. While current guidelines recommend 150 minutes of moderate-intensity physical activity or 75 minutes of vigorous activity per week, exercise snacks can deliver measurable benefits in far less time – sometimes just a few minutes daily.

A 2024 randomised controlled trial compared stair-climbing exercise snacks to 40 minutes of moderate-intensity cycling three times weekly. Remarkably, the exercise snacks group – doing three 30-second, all-out stair climbs per session – improved their fitness by 7%, while the cycling group showed no significant change.
The potential benefits extend beyond fitness. A large-scale study of over 25,000 adults who didn’t exercise found that those who accumulated just three to four minutes of vigorous activity daily through activities such as fast walking or climbing stairs had a 40% lower risk of dying from any cause. They also had a nearly 50% lower risk of dying from cardiovascular disease compared to those who did none.
There’s evidence that exercise snacks have blood sugar benefits, too. Research has shown that brief, intense exercise snacks performed before meals can reduce post-meal blood sugar spikes in people with insulin resistance (a precursor to type 2 diabetes) – potentially good news for anyone concerned about their metabolic health.
The best exercise snacks
The beauty of exercise snacks is their flexibility. You don’t need special equipment, a gym membership, or to even change your clothes. Here are some practical ways to incorporate them into your day:
Stair climbing is perhaps the most researched exercise snack. If you work in an office building or live in a block of flats, you’ve got free exercise equipment at your disposal.
Try climbing vigorously – fast enough that you’re breathing hard by the top – for 20-60 seconds, two to three times throughout your day. Earlier research found that women who progressively increased their stair climbing to five ascents daily saw a 17% improvement in fitness after just eight weeks.
Walking bursts count too, provided they’re vigorous. Try doing a brisk one-minute walk around the office or a quick lap of your garden a few times a day. But in order to see benefits, you’ve got to make sure the pace is quick enough that holding a conversation becomes difficult.

Bodyweight exercises such as squats, lunges or wall push-ups can be done almost anywhere. Try a set of ten squats every time you make a cup of tea or some wall push-ups before lunch. The key is intensity – you should feel your heart rate rise and be slightly out of breath.
Consistency matters more than perfection when it comes to exercise snacks. The research shows that even very brief sessions – as short as 20 seconds – can contribute to fitness improvements so long as they’re repeated regularly.
The trick is building these snacks into existing habits. Climb stairs before your morning coffee. Do squats during TV adverts. Take a brisk walk after finishing a work call.
Exercise snacks won’t replace the full range of benefits you’d get from a comprehensive fitness programme. But for the millions of us who struggle to find time for traditional workouts, they offer a practical entry point – one backed by increasingly robust science.
The biggest gains in health happen when someone goes from doing nothing to doing something. So next time you’re waiting for the kettle to boil or have a few minutes between meetings, consider having an exercise snack. Your heart will thank you.

For Hobart teacher Mary Holton, health means everything.
She started feeling the squeeze from cost-of-living pressures when fuel prices spiked again.
“Going out for just fitness alone was a bit much,”
she said.

Many Tasmanians are feeling cost-of-living pressures in a very physical way, with locals saying exercise routines are being dropped, health appointments delayed and wellbeing pushed to the bottom of the list as budgets tighten.
Ms Holton relies on multiple physiotherapy sessions each week, but says paid fitness classes simply are not an option.
“That costs … so to actually go to other classes as well, it’s out of my budget really.“

National data shows that almost half of Australians already fall short of minimum physical activity guidelines, and rising prices are making even basic care unaffordable for many.
Consultant clinical psychologist academic Kimberley Norris says this is exactly how unhealthy patterns begin.
“We tend to focus on the most stressful thing first … and health is one of those things we don’t think about until things go wrong,”
Professor Norris said.

For Ms Holton, going to a free workout group in her local community was a game-changer.
“Came down and absolutely loved it. It’s really nice to have a group and it just keeps growing,” she said.
Finding a free exercise group has drastically improved her health, as noted by her GP, and she is part of a growing trend.
Free exercise classes become a lifeline
At a community exercise class in South Arm, south-east of Hobart, the mood is upbeat, with laughter, movement, and a sense of relief.
Participation has more than doubled in the past year, with more than 100 Tasmanians now involved.
Trainer Ollie Mathewson said the surge was unmistakable.
“It’s free of charge for everybody … and over the last 12 months I’ve noticed a lot more people starting to come along,”
he said.

Across greater Hobart, free and low-cost alternatives are multiplying and include walking groups, community-run circuits, and morning and afternoon fitness meet-ups.
Tasmanians are increasingly organising their own solutions.
Mr Mathewson said connections drive outcomes.
“A lot of people talk about weight and strength, which are obviously insanely important, having other people there to push you single every week makes it a hundred times easier.“
Professor Norris said one’s health can be prioritised for free.
“What we know about health is, it’s more about sustainable wellbeing, it’s about quality of life,” she said.
“So rather than focusing on how much you can deadlift, how far you can run, it’s about how your life has improved and how close your life is to the way you want to live it.”
She said free options were vital because once people stop moving, it becomes harder to start again.
“If we develop routines in which health is not a priority, then we almost get stuck in this cycle of health always being last.“
Health appointments being delayed or dropped
For some Tasmanians, the financial pressure is forcing even tougher choices.
Amy Dakin says she can’t even think about getting a gym membership with all the other costs of living on her mind. (ABC News: Jake Grant)
Amy Dakin, who lives with a compromised immune system, often has no choice but to delay essential care.
“My health needs to be prioritised, but your bills come first, really,” she said.
Jordyn Rowbottom says she’s not the only one changing her hobbies to save on costs. (ABC News: Jake Grant)
Jordyn Rowbottom has seen the same pattern around her.
“People are being forced to cut what they can access,”
she said.
Professor Norris warns that these short-term decisions can create long-term harm, not just for individuals, but for the broader health system.
She said the combination of financial pressure and reduced physical activity would create a public health challenge.
Trainers adapting to shrinking budgets
Personal trainer Nickola Orr works with clients across different income levels, ages and needs.
She said affordability now shapes almost every program she designs.
“You want to make sure they can get as much help as they can within their price range,”
she said.

With the median individual spend on fitness in Tasmania sitting at almost $600 last year, Ms Orr said the warning signs were already visible.
“We’re going to see more results of long-term neglect; higher injuries, more need for mental health assistance. It’s going to snowball.”
Her concerns echo Professor Norris’s academic findings that once healthy routines break down, the consequences ripple for years.
“The changes are very small … while they add up over time, there is no immediate impact,”
Ms Orr said.
Calls for more free and low-cost options
Mr Mathewson hopes the success of free community classes will inspire governments and private operators to expand accessible fitness programs.
“More free options would be a great thing. There are a few now, but there should be more,” he said.
The Tasmanian government has said it will release its 20-year preventive health strategy this month, titled The Health Revolution.
A Department of Health spokesperson said the strategy “will address the broader social, economic, and environmental factors that influence health and wellbeing”.
“Specific issues about access to health services and programs are being considered through the Access to Health Services project, a Commonwealth-State partnership.
“The Health Revolution will complement that project by addressing the root causes of poor health and the underlying conditions to make it easier for Tasmanians to live well.“
If you’ve been faithfully logging your 30 minutes of moderate exercise most days of the week, you’re getting the recommended weekly about of cardio. But a new study1 suggests that for women in midlife, that standard benchmark may not be moving the needle on cardiovascular fitness as much as we’ve assumed. Here’s what you need to know.
EL MONTE, Calif. (KABC) — A boutique fitness gym in the San Gabriel Valley is focused on women’s empowerment, offering everything from dance fitness to pilates, yoga, zumba and circuit training. It’s called “Beastin Beauties” in El Monte.
“ Boutique fitness spaces here, it doesn’t exist here, so I needed to have this for the people in my community here, where I grew up,” said owner Jay Armada.
Members love working on their health and fitness alongside other women.
“You walk in and you feel like you’re able to let loose and inhibit it in a way that you don’t find in other places,” said member Esmeralda Cabral.
“It takes away the stresses of being in a space where you may feel judgment from others. And there’s a certain level of comfort as a woman that you wanna be able, especially if you’re starting a health journey or you’re reigniting it, you wanna have the comfort of being around under supportive women,” said member Ruby Rose Yepez, who also teaches yoga at the studio.
Women empowerment has been the theme all along, from Jay’s humble beginnings…
“ I want people to feel what I felt when I was going through my own journey. I had lost ninety-three pounds in a whole year and I just wanted everyone to feel that,” said Armada.
…to a huge setback in 2020 when the gym’s previous location burned down in a fire.
“ I thought I didn’t wanna do it anymore. Maybe it was a sign from God that you should just quit. But my community held me up and they just really made me believe in it again,” said Armada.
Now, her business is thriving, and she was just named the city’s Woman of the Year!
“ Community and connection here in this space is super, super important. Jay is not just about bringing people here for health. She brings people here to build the connections so that they feel that they’re part of a community,” said Yepez.
“You build a connection without even really trying. You’re all experiencing the same moments together. There’s always just so much fun happening,” said Cabral.
