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 intense 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.
