Recent research shows that the number one reason people say they don’t exercise is that they don’t have enough time. Even though it’s easy to wonder how much time those same people spend on, say, TikTok, even the most fitness-obsessed (it me) among us have a hard time fitting in workouts. But it turns out that our favorite excuse doesn’t hold up in the face of science, because a new study suggests that we really don’t need that much time. It’s high intensity interval training (HIIT) to the rescue once again: Apparently, doing intervals of short, four-second exercises has surprising health benefits.
The research, which was published in July in the journal Medicine & Science in Science & Exercise, looked at the effects of short bursts of power cycling — a.k.a. pedaling really fast on bikes with heavy weights.
