Setting aside time for a 30- or 60-minute workout is ideal, “but you can burn a lot of calories in not-so-ideal workout situations, too,” says Katula. In fact, there’s nothing wrong with breaking up your 150 recommended minutes of weekly moderate exercise into short bursts throughout your day. “If you can fit in 10 minutes in the morning, 10 minutes at lunch, and 10 minutes at night, and you can do that five days a week, you’re there,” he says.
Katula tells his patients to think of burning calories they way they think of saving money. “We do so many little things—clip coupons, buy store brands—to save a dime here or a quarter there, because we know it adds up,” he says. “Exercise is the same way: A few push-ups here and a few extra steps there can add up, too, if you do it regularly.”
