A 180-pound person burns about 1.43 calories per burpee. So if you can hammer out at least seven a minute you’re in the double digits. But you should shoot to average at least 10 every 60 seconds, or a rate of 14.3 calories per minute. Why? Performing just 10 reps at a fast pace can rev your metabolism as much as a 30-second, all-out bike sprint, according to a study presented at the American College of Sports Medicine annual meeting.
