Can You “Microdose” Exercise?

Ten minutes can feel like nothing or everything, depending on what you’re doing. One morning, I squeezed in a quick HIIT workout before getting ready and heading out, and it made me wonder if such a short burst of exercise actually counts. It just seemed too quick compared to my typical 60 minutes in the gym.

After all, ten minutes barely covers a YouTube video these days or even the time it takes to make a meal. Yet, shorter workouts are becoming more popular, especially as schedules get tighter. There has been a steady rise in things like “10-minute workouts,” and it’s easy to see why when people have less time during the day to hit the gym.

With time always feeling limited, I decided to change things up and focus only on short workouts for a couple of weeks. I wanted to see if these quick sessions could realistically fit into a busy routine and still make a difference.

Balancing everything throughout the year gets tough. Between running multiple businesses, fitting in my workouts, coaching two baseball teams, playing with my kids, and being a good husband, my time is maxed out.

You probably feel the same way.

In this article, we are going to look at microdosing exercise and see if the research backs up this training method.

What Does Evidence Say?

According to the World Health Organization, adults should aim for at least 150 minutes of moderate-intensity aerobic exercise each week, or 75 minutes of vigorous activity. You can also combine both, depending on what suits your routine.

Moderate intensity usually means it’s hard to hold a full conversation, while vigorous activity leaves you short of breath by the end.

This can include activities like brisk walking, cycling, running, swimming, rowing, or team sports such as football and basketball.

If you’re active every day, this breaks down to roughly 20 to 30 minutes per session. Alternatively, you could fit in a few longer workouts or matches across the week.

The guidelines also suggest adding muscle-strengthening exercises, such as weight training or high-impact activities like sprinting, at least twice a week.

A 2019 review of 19 studies involving over 1,000 participants examined this. It found that multiple short sessions spread throughout the day improved heart and lung fitness, as well as blood pressure, just as much as a single longer workout.

In some cases, these shorter sessions also showed:

Better weight loss
Lower cholesterol levels

A common comparison used in these studies was:

Three 10-minute sessions per day, five days a week

vs.

One 30-minute session per day, five days a week

Exercise snacks (no, not the snacks you’re thinking of)

Another 2019 study looked at how very short bursts of exercise, often called “exercise snacks,” affect fitness. The study was small, but the results were surprisingly strong.

Participants in the snack group did three short sessions a day, three times a week, for six weeks. Each session included:

A 2-minute warm-up
A 20-second all-out sprint
A 1-minute cool-down

That’s just 3 minutes and 20 seconds per session.

The comparison group trained once a day, three times a week, but for longer. Their session lasted around 10 minutes and included multiple sprint intervals with recovery time in between.

Despite spending less time overall, the snack group still showed clear improvements in aerobic fitness, which is closely linked to long-term health and longevity.

Some research also suggests this approach may help lower cholesterol. However, the total volume of exercise may still be too low to drive meaningful weight loss on its own.
