It’s a universal law of fitness: The less time you have, the easier it is to find excuses to skip a cardio workout. After all, doesn’t a good routine require at least 30 minutes?
No, actually, it doesn’t. I’ve found that you can achieve the fastest results with the shortest cardio workouts. It’s basic exercise science: The harder you go, the more calories you burn every minute. And unlike slow-and-steady running, cardio at a fast, furious pace can speed your metabolism for hours after your workout. So you lose lard even while you’re sleeping. What’s more, research shows that brief, intense bouts of exercise can improve your cardiovascular fitness as much as jogging can.
These circuit workouts can be performed in your basement, and they’re as challenging as a series of gut-wrenching sprints. Try one, and you’ll never again think “running” when you hear the term “cardio.” The bonus? Faster workouts leave you with fewer excuses.
