It’s hard to believe you can actually get a solid workout in within the span of five minutes. But 60-second high-intensity workouts were shown to be just as effective at improving health and fitness as 45 minutes of moderate exercise in a study published in the journal PLOS One. (Full disclosure: That doesn’t mean you can just sweat for one minute; the study involved 10 total minutes of working out with 60 cumulative seconds of strenuous exercise).
But if you’re short on time, you can definitely pack at least 60 seconds of high-intensity interval work into five minutes. You can’t phone it in, though; if you’re only going to work out for five minutes, every minute should leave you breathless and feeling like you’ve pushed your body to the limit. That’s the whole premise of high-intensity workouts, after all.
