Exercise Snacks: Short Bursts of Exercise That Add Up
Exercise snacks are short bursts of effort, from a few seconds to a couple of minutes, spread through your day: a fast climb up the stairs, a set of squats to a chair, a brisk walk up a hill. A large 2022 study found that people who didn't exercise but did about three 1 to 2 minute bursts of vigorous activity a day had a much lower risk of dying over the next 7 years. Snacks don't replace proper strength sessions, but they're an easy way back in and a good way to fill the days between.
What counts as an exercise snack
Anything short that gets you breathing hard or makes your muscles work, done on its own rather than as part of a workout. Researchers call the everyday version vigorous intermittent lifestyle physical activity, or VILPA. The World Cancer Research Fund lists examples like power walking, climbing stairs, carrying heavy shopping and energetic play with kids. You probably do some already. The trick is doing them on purpose, a bit harder.
What the research found
In the VILPA study, published in Nature Medicine in 2022, Emmanuel Stamatakis and colleagues looked at 25,241 UK adults who said they didn't exercise (average age about 62). They wore wrist trackers for a week and were followed for almost 7 years.
- The typical person did about 3 short bursts a day, each lasting 1 or 2 minutes.
- Compared with no bursts, that was linked with a 38 to 40% lower risk of dying from any cause or from cancer, and a 48 to 49% lower risk of dying from heart disease.
That's an association, not proof that the bursts caused the difference. People who move briskly in daily life may be healthier in other ways. But it's encouraging, especially if you're starting from nothing.
Snacks can build strength and fitness too. In a small 2019 pilot study, 20 adults aged 65 to 80 did five 1-minute bodyweight moves (sit-to-stands, knee bends, marching, calf raises) twice a day at home. After 4 weeks, the snack group's 60-second sit-to-stand score went from 29 to 38 reps. A 2024 trial of 90 pre-frail adults over 65 found 12 weeks of home strength and tai chi snacks improved strength and balance scores more than usual routine. And in a McMaster University study, sedentary young adults who climbed three flights of stairs hard, three times a day, three days a week, improved their fitness in 6 weeks.
Exercise snack ideas
| Snack | How to do it | How long |
|---|---|---|
| Stair climb | Climb 2 or 3 flights at a fast pace. Hold the rail | Under a minute |
| Squats to a chair | Sit down and stand up, no hands, 10 to 15 times | About a minute |
| Uphill walk | Pick the steepest block near you and walk it briskly | 1 to 2 minutes |
| Counter push-ups | Hands on the kitchen counter, body straight, 8 to 15 reps | 30 to 60 seconds |
| Calf raises | Up on your toes at the sink, 15 to 20 times | About a minute |
| Heavy carry | Carry the heavy shopping bags tall, like a farmer's carry | As far as the car |
Aim for effort that leaves you breathing hard or feeling the muscles by the end. Then stop. That's the whole snack.
How snacks fit around your strength sessions
Snacks are the in-between food, not the meal. Two or three proper strength sessions a week are still where you build muscle, because that's where the weight goes up over time. Here's how many days a week to lift.
- On lifting days, skip the snacks or keep them light. You've done the work.
- On the days between, do 3 or 4 snacks. They keep you moving without adding much fatigue.
- On a busy week, snacks keep the habit alive when a full session won't fit.
How to start if you're coming back
- Week 1: 2 easy snacks a day. Chair squats in the morning, a brisk walk to the mailbox after lunch.
- Week 2: 3 snacks a day, with one a little harder, like the stairs.
- Week 3: Keep 3 snacks a day and add two full-body strength sessions.
- Week 4: Three strength sessions, with 3 or 4 snacks on the days between.
Tie each snack to something you already do: the kettle boiling, a phone call, getting home. That's how small things turn into a habit.
A week of exercise snacks plus strength
Three strength days from Liftspan's free Full Body, 3 days plan, with snacks on the days between.
| Day | Session | How long |
|---|---|---|
| Monday | Full Body A | About 45 minutes |
| Tuesday | 3 or 4 snacks: stairs, chair squats, counter push-ups | 5 to 10 minutes in total |
| Wednesday | Full Body B | About 45 minutes |
| Thursday | 3 or 4 snacks: uphill walk, calf raises, stairs | 5 to 10 minutes in total |
| Friday | Full Body C | About 45 minutes |
| Saturday | A walk with a hill in it, plus a couple of snacks | 30 to 45 minutes |
| Sunday | Rest | None |
Full Body A, B and C each cover a squat, a hinge, a push, a pull and a carry or core move, in about 45 minutes.

Common questions
What is an exercise snack?
A short burst of exercise, usually under 2 minutes, done on its own during the day. Climbing stairs fast, a set of squats to a chair or a brisk uphill walk all count.
How many exercise snacks a day should I do?
In the 2022 VILPA study, the typical person did about 3 bursts of 1 to 2 minutes a day, and that was linked with a lower risk of death. Three or four a day is a good target.
Can exercise snacks build muscle?
They can improve leg strength, especially if you're starting from a low base. Small studies in older adults found better sit-to-stand and strength scores after a few weeks. To keep building muscle, you'll need proper strength sessions where the weight goes up over time.
Do exercise snacks count toward the 150 minutes a week?
A few minutes a day won't add up to 150 on their own, but they're still worth doing. Treat snacks as a bonus on top of your walks and strength sessions, not a replacement for them.
