We’re huge fans of running. It allows you to get a stress-reducing, endurance-boosting workout with just a pair of shoes and an open road.
It also burns kilojoules, of course. At a 6-minute-per-kilometre pace—roughly the average guy’s marathon pace—you’ll fry about 40 kilojoules a minute.
That’s a solid number, and if you run faster, you can burn even more.
But if running isn’t your favourite cardio activity, there are plenty of other modes of exercise that can help you torch joules at a lightning fast rate.
“In general, you burn more calories by doing high-intensity weight training than you do running,” says Harold Gibbons, a trainer at Mark Fisher Fitness.
Most people don’t realise this, though. That’s often because the number of calories you’re told you just burned is typically estimated from The Compendium of Physical Activities, which calculates energy expended through aerobic metabolism.
That works well for low- to medium-intensity exercise, but not so well for higher-intensity activities that rely on anaerobic metabolism.
In fact, when researchers at the University of Southern Maine used a more advanced method to estimate energy expenditure during exercise, they found that weight training burns up to 71 per cent more calories than originally thought. Which suggests that a fast-paced circuit workout burns as many calories as running at a 4-minute per kilometre pace.
But resistance training isn’t your only option. There are also cardio exercises that can boost your burn, too. We found 10 exercises that will help you incinerate calories—without ever having to hit pavement.
This explosive cardio exercise works the big, powerful muscles around your glutes and quads, and sends your heart into overdrive, according to research from the University of Wisconsin.
In the study, participants burned 20.2 calories a minute and their average heart was 93 per cent of its max for the course of a 20-minute workout.
“The kettlebell swing works you so hard because it’s not a movement you’re used to,” says strength coach Dan John. “You’re not super efficient at it, which taxes your body.”
An 85kg guy can burn 377 calories during 30 minutes of vigorous rowing, or about 12.5 calorie per minute, reports a Harvard University study.
And because you need to utilise the muscles in your arms, legs, and back for efficient strokes, it's a great total-body trainer.
A 75kg person burns about 1.43 calories per burpee, says exercise scientist and Spartan Coach Jeff Godin. 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, and that makes the burpee a killer cardio exercise.
AirDyne Bike Sprints
It sounds downright crazy, but Gym Jones manager Rob MacDonald proved that it's possible to blast 87 calories in one minute on this stationary bike that increases its resistance as you pedal harder.
The key: Give everything you have in that 60 seconds.
Note: This was by no means a scientific experiment, and relies on the accuracy of the built-in AirDyne monitor, which calculates calories by converting revolutions of the fan into physical work.
Moderate-intensity rope jumping—about 100 to 120 skips per minute—burns about 13 calories a minute, according to the Compendium of Physical Activities.
This cardio exercise uses more muscle groups than jogging, and challenges your balance and coordination—especially if you practice drills that require extra hand and foot skills.
This CrossFit Workout of the Day (WOD) burns an average 13 calories per minute, according to scientists at Kennesaw State University.
It’s effective because it pairs three exercises—5 pull-ups, 10 push-ups, and 15 air squats—that work different major muscle groups, and you do as many rounds as possible in 20 minutes.
So if you’re in amazing condition, you can go all-out for each one, without slowing down or stopping to recover in between.
If you’re somewhat less than amazing (read: like most people), you simply rest when needed. For example, you don’t move on to the push-up until you’ve completed 5 reps of the pull-up, even if you have to stop and start.
“Any routine that takes you from standing, down to the ground, and back up to standing again is an amazing calorie burner, because it really spikes the heart rate,” says John. And for the fuel your body needs to exercise hard—and recover fast
Zipping along on skis delivers a better cardio workout compared to running at about the same pace, thanks to the fact that the sport requires you to push with your lower-body and pull with your upper.
In fact, a good cross-country ski session can burn more than 12 calories a minute, according to the Compendium of Physical Activities.
That explains why Nordic Skiers consistently collapse in exhaustion at the finish line of Olympic races.
Tabata Jump Squats
This four-minute miracle drill burns major calories both during a workout and after. In an Auburn University at Montgomery study, participants who did eight rounds of all-out jump squats—20 seconds of hard work, separated by 10 seconds of rest—burned 13.4 calories per minute and doubled their post-exercise metabolic rate for at least 30 minutes.
In a recent College of New Jersey study comparing various workout styles, battling-rope exercises came in first in terms of total oxygen consumption and an average calorie burn of 10.3 calories per minute.
