What exercise burns the most calories?

You picked the workout that felt hardest, finished drenched, and your watch said 600 calories. Then the scale didn't move, and the next session felt even harder to start. If that sounds familiar, you've run into a quiet rule of calorie burning: the exercise that burns the most on paper is often the one you can keep up for the fewest minutes.

Most calorie rankings agree on the top five. What they rarely show is how the numbers change with your body weight, how long anyone can hold those paces and how small the afterburn really is. This page covers all three, then the best options at home, with dumbbells and on gym machines, whether weight lifting burns calories and how to burn calories fast.

The Exercises That Burn the Most Calories, Ranked

The 2024 Adult Compendium of Physical Activities by Herrmann and colleagues lists the energy cost of 1,114 activities in METs, multiples of the energy you use sitting still, and 912 of those values come from lab measurements. This ranking uses the hard pace a fit adult can hold for 20 to 30 minutes, shown in bold, with calories per hour for a 150 lb person.

1. Running at 8 mph: 12.0 METs. About 815 calories an hour at a 7.5-minute mile, and about 635 at 6 mph, a 10-minute mile. The cost of each mile barely changes with pace, as our breakdown of how many calories a mile burns shows, so running faster mostly buys calories per minute.
2. Cycling at 16 to 19 mph: 12.0 METs. About 815 calories an hour, and about 680 at 14 to 15.9 mph. A stationary bike at 151 to 199 watts rates 10.3 METs.
3. Jumping rope at 100 to 120 skips a minute: 11.8 METs. About 805 calories an hour, and 835 at 120 to 160 skips. Most people stop to rest often, so a real session averages less.
4. Cross-country skiing at a brisk pace: 11.3 METs. About 770 calories an hour, because your arms and legs both drive you forward.
5. Rowing machine at 150 to 199 watts: 11.0 METs. About 750 calories an hour, rising to 955 at 200 watts or more.
6. Bodyweight HIIT: 11.0 METs. Intervals of burpees, mountain climbers and squat jumps burn about 750 calories an hour while you're working.
7. Swimming fast front crawl: 10.5 METs. About 715 calories an hour, and butterfly rates 13.8 METs.
8. Kettlebell swings: 9.8 METs. About 665 calories an hour, the highest of the Compendium's weight-training entries.
9. Climbing stairs fast: 9.3 METs. About 635 calories an hour. Running up stairs rates 15.0, the top value on this page, but it lasts only as long as the staircase.
10. Elliptical at a vigorous effort: 9.0 METs. About 610 calories an hour, with far less impact than running.

Running tops the list for most people for a practical reason as well as a numerical one. It's weight-bearing, it works most of your muscle, and people reach a higher peak on a treadmill than on a bike: the FRIEND registry's median values for peak oxygen uptake are higher for treadmill tests than for cycle tests, according to Kaminsky and colleagues (2022). Yoga sits at the other end of any calorie ranking, and our look at how many calories yoga burns shows where each style lands.

Calories Burned Per Hour by Body Weight

Calories rise almost in proportion to body weight, because a heavier body costs more to move. The table uses the Compendium's own approximation of 1 MET as about 1 calorie per kilogram of body weight per hour, so calories equal METs times kilograms times hours, rounded to the nearest 5. Our calories burned calculator uses the oxygen-based version of the same conversion, which reads about 5 percent higher.

These are gross figures, so they include the 1 MET you'd burn anyway, about 70 calories an hour at 150 lb. Halve a row for a 30-minute session. Every value is an average with a margin of error, which our breakdown of how many calories swimming burns explains. The 2024 values come from adults aged 19 to 59, so treat them as a rougher guide past 60.

Why Sustainable Minutes Beat Peak Burn

Every row in that table assumes you keep going for a full hour. Almost nobody does at the top of the list, and that changes the answer more than the ranking does.

Your fitness sets your hourly ceiling

Your VO2 max is the most oxygen your body can use, and it caps the energy you can burn for more than a few minutes. Divide it by 3.5 to get it in METs. In the FRIEND registry's data from 7,783 treadmill tests, reported by Kaminsky, Arena and Myers (2015), the median VO2 max for men in their 40s was 37.8 mL/kg/min, about 10.8 METs. For women in their 40s it was 26.7, about 7.6 METs. In their 20s the medians were about 13.7 METs for men and 10.7 for women, and a 2022 update put the treadmill values 1.5 to 4.6 mL/kg/min lower.

Nobody works at 100 percent of that for long. The hard sessions in the trials below ran at 65 to 80 percent of each person's peak. Picture a woman in her 40s with median fitness who weighs 150 lb. At about 75 percent of a 7.6-MET ceiling she can sustain roughly 5.7 METs, or about 390 calories an hour, whichever exercise she picks. Jumping rope at 11.8 METs is above her maximum, so she can only do it in bursts, and the rests pull her average back to what her fitness allows. A man in his 40s with median fitness at 180 lb can hold about 8 METs, close to 660 calories an hour. Both ceilings rise with training, which is how the burn of your workouts really grows.

The amount you do predicts fat loss better than intensity

Two randomized trials separated how much exercise people did from how hard they did it. In the STRRIDE trial, Slentz and colleagues (2004) gave 120 sedentary adults with overweight one of three eight-month programs and asked them not to diet. The group doing the equivalent of about 20 miles of jogging a week lost 2.9 kg of body weight and 4.8 kg of fat. The two groups doing the equivalent of 12 miles a week lost less, and about the same as each other, whether they jogged at 65 to 80 percent of peak oxygen uptake or walked at 40 to 55 percent. The control group gained a kilogram.

Ross and colleagues (2015) then matched the calories directly. Over 24 weeks, 300 adults with abdominal obesity burned the same calories per session at either 50 or 75 percent of their peak. Waist size fell by 4.6 cm in both groups, and weight loss didn't differ. The harder sessions took 40 minutes against 58. Intensity saved time, and it didn't add fat loss.

A day's burn is minutes times METs

Multiply the MET value by the minutes and the ranking often flips. An hour of brisk walking at 4.8 METs burns about 325 calories at 150 lb, while 15 minutes of jumping rope at 11.8 METs burns about 200. The rope wins per minute, the walk wins for the session, and you can walk again tomorrow. Our guide on how to burn 1,000 calories a day builds a whole day this way.

How Big Is the Afterburn?

The afterburn, or excess post-exercise oxygen consumption, is the extra energy you use while your body recovers from a workout. It's real, and it's smaller than the marketing suggests. Panissa and colleagues (2021) reviewed 22 studies comparing it after interval and steady sessions. In the three hours after exercise, interval sessions added about 136 kJ, roughly 33 calories, against about 24 for steady cardio, and all-out sprint intervals added about 58. Studies that measured for longer found about 69 calories after intervals and 38 after steady work.

The top of the range comes from a long, hard ride. In a sealed metabolic chamber, Knab and colleagues (2011) had 10 young men cycle for 45 minutes at about 73 percent of their VO2 max. The ride cost 519 calories, and over the next 14 hours they burned 190 more than on a rest day, an extra 37 percent. A typical 20-minute class doesn't come close to that session.

So count the afterburn at about 25 to 70 calories for an ordinary workout, and up to a couple of hundred after a long, hard one. Treat it as a small bonus on top of the session. Our review of the research on the afterburn effect covers how intensity and duration change it.

What Exercise Burns the Most Calories at Home?

At home, running up the stairs, jumping rope and bodyweight HIIT burn the most calories. Here's how the home options rank, with calories for 20 minutes of steady work at 150 lb:

• Running up stairs: 15.0 METs, about 340 calories, if you have a long flight and healthy knees.
• Jumping rope: 11.0 to 12.3 METs, about 250 to 280.
• Bodyweight HIIT with burpees, mountain climbers and squat jumps: 11.0 METs, about 250.
• Climbing stairs fast, one step at a time: 9.3 METs, about 210.
• Step aerobics on a 10 to 12 inch step: 9.0 METs, about 205.
• High-impact aerobic dance: 8.0 METs, about 180.
• Burpees and jumping jacks as steady calisthenics: 7.5 METs, about 170.
• Hard bodyweight strength work such as squats, lunges and push-ups: 6.5 METs, about 145.
• Jogging in place: 4.8 METs, about 110.

One study measured a home-style session directly. Emberts and colleagues (2013) had 16 fit adults do a 20-minute Tabata workout of high knees, jumping jacks, burpees, squats, lunges, push-ups and box jumps, in 20-second bursts with 10 seconds of rest. They averaged 14.5 calories a minute, 240 to 360 for the session, at about 74 percent of their VO2 max. The men averaged 94 kg and the calories were predicted from heart rate, so a lighter or less fit person will burn less.

Plain squats land near the bottom of this list, and our page on how many calories squats burn works through the per-rep numbers. Strength moves still belong in a home plan, because they keep your muscle while the cardio carries the calories.

Dumbbell Workouts That Burn the Most Calories

How you use a pair of dumbbells changes the calorie burn more than the dumbbells do. In the Compendium, traditional sets of 8 to 15 reps rate 3.5 METs, vigorous heavy lifting 6.0 and a circuit with weights and minimal rest 7.5. Kettlebell swings rate 9.8, and many people do the same swing with one dumbbell held by its end.

Swings feel harder than they burn, though. Hulsey and colleagues (2012) had 13 young adults do a 10-minute swing routine and then a treadmill run at the same perceived effort. Heart rate matched, at about 90 percent of age-predicted maximum, yet the run used 25 to 39 percent more oxygen and calories. In 12 minutes of continuous swings, Farrar and colleagues (2010) measured heart rate at 87 percent of maximum while oxygen use sat at 65 percent of VO2 max, which works out to roughly 13 calories a minute for those 77 kg men. That gap is why a watch that leans on heart rate tends to overcount strength circuits.

A 20-minute dumbbell circuit

Set a timer for 40 seconds of work and 20 seconds of rest, and go through these five moves four times:

1. Dumbbell swings, driven by your hips.
2. Thrusters: a squat that flows straight into an overhead press.
3. Renegade rows from a push-up position.
4. Step-ups onto a sturdy step with the dumbbells at your sides.
5. Mountain climbers.

At 7.5 to 9.8 METs, that's roughly 170 to 220 calories at 150 lb, and more at higher body weights. Choose weights you can move briskly with good form for every rep of the 40 seconds.

Does Weight Lifting Burn Calories?

Yes, but less per hour than cardio, mostly because of the rests between sets. Typical weight training at 3.5 METs burns about 240 calories an hour at 150 lb. Loaded squats and deadlifts rate 5.0, about 340 an hour, and a vigorous session reaches 6.0, about 410. Turn the same moves into a circuit with minimal rest and the Compendium rates it 7.5, about 510 an hour.

The muscle you build adds a little to your resting burn. Wang and colleagues (2010) confirmed that skeletal muscle burns about 13 calories per kilogram per day at rest, against 4.5 for fat, so 2 kg of new muscle adds roughly 26 calories a day. The bigger payoff during weight loss is keeping the muscle you already have, which our look at whether weight lifting burns fat covers with the trial numbers.

What Exercise Machine Burns the Most Calories?

At a hard pace, the rowing machine and a treadmill set to an incline burn the most calories of the common gym machines, with the ski erg and the stationary bike close behind. Here's how they compare at 150 lb:

The setting matters more than the machine. A 5 percent incline lifts a 6 mph run from 9.3 to 13.3 METs, and a rower goes from 5.0 METs below 100 watts to 11.0 at 150 to 199. At home, a rower or a bike fits in a spare corner, though a jump rope and a staircase reach the top half of the list without either.

How to Burn Calories Fast

These five changes raise the calories you burn in the time you already have:

• Use the most muscle. Whole-body, weight-bearing exercise like running, rowing and jumping rope burns more per minute than seated or arms-only work.
• Add a hill. An incline makes you lift your body weight with every step, which is why a 5 percent grade adds over 40 percent to a 6 mph run.
• Cut the rest. The same dumbbell moves rate 3.5 METs as traditional sets and 7.5 as a circuit with minimal rest.
• Use intervals when time is short. They pack more work into fewer minutes, but in the Ross trial they didn't beat a longer steady session that burned the same calories.
• Go a little longer. Ten more minutes at a pace you can hold adds about 55 to 135 calories at 150 lb, depending on the activity.

What This Means for You

The exercise that burns the most calories for you is the hardest whole-body activity you can repeat for 30 to 60 minutes, most weeks. For most people that's running, cycling, rowing or a brisk walk that gets a little longer each month. As you get fitter you can hold a faster pace, so the same 40 minutes burns more than it did when you started.

If keeping it going is the hard part, the fix is a plan built around consistency. FitCraft's 3D AI coaches lead cardio, bodyweight and dumbbell workouts at home and demonstrate every exercise, and the app's streaks and leaderboards give you a reason to come back on low-motivation days. If you're choosing an app to keep those minutes coming, our ranking of the best workout apps for weight loss sets out seven options and the catch with each.
