What Are ‘Exercise Snacks’ and Can They Really Stabilize Blood Sugar Levels?

Here’s what experts say about exercise snacks and how they can influence blood sugar control, along with tips for building small movements into your existing routine for meaningful blood sugar benefits.

The Science Behind Exercise Snacks and Blood Sugar

“Short bouts of movement — or exercise snacks — help accelerate this process,” says Andrew Koutnik, PhD, research faculty at the Florida State University Institute for Sports Science and Medicine in Tallahassee. “Over time, regularly doing short bouts of movement also improves insulin sensitivity, which means your body needs less insulin to store the same amount of glucose. And these benefits apply to people with and without diabetes.”

In other words, every brisk walk, quick stair climb, or set of squats can give your body an opportunity to regulate blood sugar levels, especially when timing is intentional.

That said, exercise snacks aren’t only beneficial after eating. “Using high-intensity exercise snacks before a meal can make the muscle more receptive to glucose. Then, low-intensity workouts after meals can help maintain higher blood flow and sugar delivery to those muscles. [This combination] may well be more effective than either approach used alone,” says James Cotter, PhD, an exercise physiologist and professor of physical education at the University of Otago in Dunedin, New Zealand.

How to Fit Exercise Snacks Into Your Day

Here’s what sprinkling exercise snacks into your daily routine, especially around mealtimes, can look like in practice.

• Take the stairs after meals. Research has found that brief stair-climbing sessions after eating can help reduce postmeal glucose spikes in people with type 2 diabetes, with repeated bouts improving 24-hour glucose control.

   To try this, Koutnik recommends taking one to three minutes to go up and down the stairs shortly after meals.
• Go for a brisk walk after lunch. Studies show that a 15-minute walk after you eat can help level out the postmeal glucose spike.

   Koutnik suggests picking a mealtime that works for you, such as aiming to walk for 5 to 15 minutes after lunch at a brisk pace — enough to slightly elevate your heart rate while still being able to hold a conversation.
• Use TV time for quick strengthening movements. Research shows around three minutes of light resistance exercise in the evening can help improve postmeal blood sugar control, making the commercial breaks (or ads on your streaming service) when you tune into your favorite TV series an ideal time for exercise snacks.

   Try calf raises, sit to stands, wall push-ups, or 10 to 20 body-weight squats during your evening TV session, Koutnik says.

• Build movement into errands. Turn everyday tasks into opportunities for activity. Try parking farther away and walking in and out of stores briskly to create built-in exercise snacks, Koutnik says. “Then, do a quick lap around the building or area before heading back to your car.”

• Make the most of waiting periods. Anytime there’s a lull at work or home, try to squeeze in an exercise snack of your choice. This could look like two minutes of marching in place or walking around the room while on a phone call or doing counter push-ups, mini squats, or heel raises while waiting for coffee, tea, or the microwave, Koutnik suggests.

Keep in mind that you don’t need to fully overhaul your routine to see potential benefits. “Whatever works in people’s days, such as walking uphill or taking several flights of stairs, these exercise snacks can provide a meaningful impact,” says Cotter.

How to Make the Most of Exercise Snacks

Generally speaking, any type of movement is better than none. But to be safe, get your doctor’s approval before adding any new types of activity to your routine. Once you have the green light, these key strategies can help turn quick exercise snack breaks into a powerful tool for glucose control:

• Focus on timing. Exercise snacks done soon after eating can have the strongest effect on postmeal blood sugar spikes.

   In practice, Koutnik says, this could look like starting your movement burst within 30 to 90 minutes after a meal. You don’t have to do this every time, but prioritizing it after your largest or most carb-heavy meal can deliver the biggest impact, he says.
• Up the intensity. While all movement counts, choosing slightly vigorous movement bursts, such as jumping jacks, over gentle stretching can have greater blood sugar benefits, Cotter explains, because you’re using larger muscle groups, such as the torso, legs, and arms. A good benchmark is to aim for about one minute of effort that feels hard or very hard, where a full conversation becomes difficult, he says.
• Incorporate micro-challenges: To keep your body adapting, gradually increase the challenge over time. This could mean adding on a few minutes to your walk, choosing a route with an incline, or adding an extra flight of stairs, says Koutnik. These small progressions can help further improve insulin sensitivity.
• Make it part of your routine, not another chore. Exercise snacks should become a habit in order to significantly affect blood sugar and cardiometabolic health.

  They’re most effective when seamlessly built into your day, as with household chores, rather than feeling like another big item on your to-do list to tackle, says Cotter.

While exercise snacks can be an effective strategy for blood sugar management, they’re not a replacement for structured workouts. The most effective approach is typically a combination of both: regular exercise for overall health, plus targeted movement throughout the day to help blunt postmeal blood sugar spikes, says Koutnik.
