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.The Conversation

Flexibility expert recommends doing this for three minutes daily to improve mobility

Longevity is something of a buzzword right now, and the idea of living better for longer is undoubtedly appealing. Mobility is a key component of this.

By definition, mobility is the ability to move freely, something that tends to deteriorate as we age. But there are simple things we can do to maintain it.

One of them is “joint flossing”, a daily practice recommended by experienced coach and mobility specialist Darren Ellis.

“Mobility is a conflation of strength and flexibility,” he says. “I always used to believe that strength was the foundation of everything in exercise. But if you’re strong and you can’t move through a decent range of motion at certain joints, you’re still suffering.

“When you reach down to pick something up from the floor and it seems further away than it used to be, you suddenly realise how crucial mobility is.”

Below, Ellis explains how to use his three-minute joint flossing protocol to help ease stiff joints and improve your ability to move.

How to try joint flossing

The body works on a rough “use it or lose it” basis. If you rarely move a joint through its full range of motion, the tissues around it can become tight, stiff and sore. The natural remedy for this is gradually reintroducing movement in the affected areas.

“The easiest place to start when improving mobility is to get the joints moving more freely with some simple joint circles,” says Ellis. “I sometimes call it joint flossing because, firstly, you are flossing nutrients through the joint by promoting blood flow in this area, and secondly, it’s something you should do regularly.”

You start with neck circles then work your way down your body from your head to your toes, as shown in the video above – if something can move, you move it.

Ellis recommends doing five to 10 repetitions per body part, using a controlled tempo and a range of motion that feels safe and comfortable for you.

“There’s no need to force anything,” he says. “You’re just giving your body a chance to move again.”

Doing this consistently will improve your physical capacity and mobility, allowing you to return to other movements and exercises over time.

Should you sync your exercise time to your chronotype?

Should you sync your exercise time to your chronotype?

A new study suggests that exercising at times that match whether someone is naturally a morning or evening person could reduce their risk of heart problems.

Researchers in Britain and Pakistan determined the chronotypes of 150 people aged between 40 to 60 through questionnaires and 48-hour core body temperature measurements.

Chronotype refers to the tendency to be naturally more active or wakeful at a particular period of the day.

All participants in the study – which was published in the journal Open Heart – had at least one cardiovascular risk factor, such as high blood pressure, obesity or physical inactivity, and were randomly assign-ed to exercise at times that either aligned with their chronotype or did not.

Workouts were scheduled either in the morning (8am-11am) or evening (6pm-9pm).

Out of the group, 134 participants completed all 60 exercise sessions.

Over 12 weeks, the study found that both the matched and mismatched groups show-ed improvements in heart risk factors, aerobic fitness and sleep quality.

However, it discovered that those who exercised in alignment with their chronotype experienced greater reductions in blood pressure.

They also demonstrated better improvements in measures such as heart rate, aerobic capacity and sleep quality, compared to those whose exercise timing did not match their natural preferences.

In light of these findings, we spoke to Nuffield Health personal training lead Sam Quinn in Britain, to find out whether or not he thinks we should all sync our exercise with our chronotype.

What are the main categories of chronotypes?

Chronotypes are often simplified into “morning larks” (early birds) and “night owls” (evening types).

“Morning people or early risers are people who find that their energy levels are optimal first thing in the morning and often find that they are more productive during the first part of the day,” says Quinn.

“Whereas, a night owl, or someone who is more of a night person, would be someone whose energy levels are optimal later in the day or the evening.

“These are generally people who like to stay up late and maybe into the early hours in the morning.”

What are some benefits of trying to sync exercise with your chronotype?

“The main benefit is that it can help you stay consistent with your exercise,” says Quinn.

“We’ve all got busy lives and everyone’s got different preferences, but the best programme is going to be the one that you’re going to be able to stick to.

“For example, if you set a workout programme where you have to go to the gym at eight o’clock in the morning and you’re a night person, you might fail before you’ve even started.

“However, if you select a time which is more suited to your preferred time of day and your body clock, where you feel more energised and it works better for your schedule, you’re going to be much more consistent and much more likely to achieve your goals, whether that’s improving your mental health, an aesthetic goal or a performance-related goal.”

Early birds benefit best from exercising in the morning before going to work.

Are there any signs that might indicate someone is working out at the “wrong” time of day?

“I think the main physical signs to look out for are to do with energy levels and performance,” says Quinn.

“For example, someone’s output might be affected.

“They might be struggling to train that day, are not turning up consistently and are struggling to hit their designated reps or loads, therefore might not be able to accomplish their physical goals in the gym.

“Also, sometimes, people look visibly deflated.

“Their energy levels are depleted, they’re looking lethargic and might not be engaging with conversation.

If someone is feeling lethargic and tired, they’re not going to get the most out of their session and they’re not going to enjoy it.”

What other factors might affect your energy levels during workouts?

The quantity and quality of your sleep can have a big impact on your energy levels during a workout.

“If you’re training regularly, but you’re not sleeping and recovering adequately, you’re not going to be energised and are not going to be able to perform at your best during your workouts,” highlights Quinn.

Stress can also sabotage your workouts.

“I would say that lifestyle-related stress is one of the biggest factors that impacts people’s energy levels, focus, motivation and frequency of workouts,” he adds.

“When people come in to train, they might vent about their work-related stress and might only get through 50% of the work that was planned for that session.

“So, stress can be a really big obstacle.”

Fuelling yourself adequately is also key.

“Make sure that you’re recovering appropriately from your workouts with the correct nutrition and are fuelling yourself appropriately, depending on what your goal is,” says Quinn.

“Try to educate yourself on these variables that are going to impact your goals – such as your sleep, nutrition, hydration and recovery – so that you can utilise all of this to help you to achieve your long-term goals.”

How can someone figure out what their chronotype is and find a routine that works for them?

“Many people think they are a morning person or have read that the best time of day to train is the morning, but when they train in the morning they feel tired and lethargic,” says Quinn.

“Some people also don’t sleep as well because they’re anticipating trying to get into the gym in the morning.

“I find that many people want to be a morning person, but actually train much better in the afternoon or the evening, when they’ve had a couple of extra hours of sleep.”

Sometimes finding a routine that works for you takes a bit of time.

“Finding the right time to train and exercise can take a bit of trial and error, and can sometimes take quite a long time to figure out,” he says.

“Be flexible and try a few different times to see what’s optimal for you, what works with your lifestyle and what is going to enable you to be consistent over time.”

When figuring this out, listening to how your body and mind feels can help guide you.

“I regularly have to communicate with my clients and ask them, ‘How are you feeling? Is this the most suitable time for you?’” he adds.

Most importantly, Quinn reminds people to choose a type of activity that they actually enjoy and will stick to.
