1. Fast-paced running

Workouts-That-Burn-the-Most-Calories,-According-to-Scienceoneinchpunch/shutterstock Running is one of the most simple athletic endeavors humans can do, mainly because no equipment is needed—technically not even shoes (though our 21st century living environment calls for them). Running for an hour at 8 mph burns 1,074 calories per hour for a 200-pound person, according to fitness expert Chris Ryan, CSCS, CPT. Because it requires a serious amount of energy to move this fast and places quite a lot of demand on your cardiovascular system, most of us can't sprint or run too fast for too long. "The best way to incorporate this exercise is to do 10–20 second sprints (or 100–200 meters, if on a track) and then jog or walk for 60 seconds," says Roger E. Adams, PhD, Houston-based dietitian and nutritionist and founder of eatrightfitness.com. "Keep repeating these intervals until you've had enough, or until your sprints look like jogs." Hoping to maximize your workout even more? Add a weighted vest to your sprints. This will drive up your calorie burn and is much safer than holding dumbbells or using ankle weights.

2. Jumping rope

Workouts-That-Burn-the-Most-Calories,-According-to-ScienceDasha Petrenko/shutterstock There's a reason some of the world's greatest boxers have relied on jumping rope to train their footwork and increase their heart rate. "Jumping rope can burn upwards of 1,074 calories per hour and is an excellent workout for the whole body," says Ryan. "Even just a few minutes of jumping rope can get your lungs burning and heart racing." One of the best parts of this calorie-torching exercise? You can do it almost anywhere, anytime, though few of us can handle it for more than a few minutes straight. "The best way to incorporate jumping rope into your exercise regimen is to do intervals," says Dr. Adams. "Jump rope for a specified number of reps, say 100, then walk around or in place for 60 seconds. Then repeat this interval until you're too tired to jump effectively." If you can jump rope for several minutes straight, go for it! Otherwise use the interval approach for maximum results. A jump rope is one of those great pieces of portable fitness gear to pack on your next vacation.

3. Taekwondo

Workouts-That-Burn-the-Most-Calories,-According-to-Sciencesittipong kitsamran/shutterstock When it comes to martial arts exercises that burn mega calories, Taekwondo takes the black belt, burning about 937 calories per hour for a 200-pound individual. Similar to wrestling or boxing, Taekwondo is a self-defense exercise that originated in Korea and has been around for about 2,000 years. Typically, you'd perform the exercise by competing against another person across from you, who is trying to weaken your technique and cause you to let your guard down. "The exercise emphasizes speed, power, concentration, reaction force, and breath control among its guiding principles, truly taking on an otherworldly athletic mindset and transforming mind and body to one powerful weapon," says Ryan. However, many people rest quite a bit between movements, so in order to keep this mode of exercise at the top of the calorie-burning spectrum, minimize rest periods and go directly into each of your movements.

4. Vigorous swimming

Workouts-That-Burn-the-Most-Calories,-According-to-ScienceSolis Images/shutterstock You've probably heard that swimming, though low-impact and relatively accessible for nearly all individuals regardless of age or injury, burns serious calories—and that's no lie. Vigorous, or high-intensity, swimming can burn upwards of 892 calories an hour for a 200-pound person. In addition to its therapeutic benefits and fine balance between strength and cardio, one of swimming's ancillary benefits is simply being in water. "Your body normally runs at 98.6 degrees, but the average pool temperature is usually around 80 degrees—so your body burns calories just by trying to keep you warm and make up for the near 20-degree difference," explains Ryan. Want to burn even more calories? Try wearing resistance gloves or using a dead-leg stroke to essentially take your legs out of the mix. Also, finding a cooler-than-normal pool or body of water to swim in will really jack up your caloric burn as your body burns more calories to stay warm.

5. Running Up Stairs

Workouts-That-Burn-the-Most-Calories,-According-to-Sciencelzf/shutterstock Nothing quite puts the hussle in a hard-earned workout quite like running up a set of stairs. Not only is it great for muscle-building and improving your cardiovascular fitness level, but it's also a serious calorie-scorcher. Running stairs can burn upwards of 819 calories per hour for a 200-pound person. "Stair running essentially elevates the heart rate while the heart and lungs pump more blood and oxygen, resulting in a higher caloric burn than doing the same distance on flat ground," explains Ryan. Your speed, number of steps, and the height of the steps will all factor in to determine your overall calorie burn. "Keeping a faster pace up the stairs and walking down is the safest approach," says Samantha Clayton, physical trainer and senior director Worldwide Fitness Education, Herbalife Nutrition. "You can vary your upward speed to increase the intensity level or, if you have the coordination, taking two steps at a time will make your muscles work harder and therefore increase your calorie burn. The more steps you climb overall, the harder your body is working. Check out these other ways to jump-start a sluggish metabolism.

6. Jogging

Workouts-That-Burn-the-Most-Calories,-According-to-Science lzf/Shutterstock Even at a relatively easy pace like 5 miles an hour, which is just above walking speed for most people, jogging is an excellent way to burn a high amount of calories. In fact, a 200-pound person can burn 755 calories per hour when running at this relaxed speed. Because it's a full-body movement, running works a great deal of muscles at the same time and challenges your cardiovascular system. It's also a fairly easy exercise to fit into people's schedules because, most of the time, all it requires is some running shoes and pavement. "If you're looking to add a little more caloric burn during your workout, try upping the incline a few percentages for short bouts of hills during your workout," says Ryan. "This helps increase the intensity of the workout, but also shifts the position of the foot strike to mimic an undulating path or trail, which becomes a much more functional way to attack a workout." Here's what happens to your body when you start a running regimen.

7. Tennis

Workouts-That-Burn-the-Most-Calories,-According-to-SciencePopartic/shutterstock Considered by many to be the ultimate form of "athletic chess," tennis is an excellent way to burn serious calories. This is mainly because of the amount of fast-paced spurts of running and body movement required in a match. "What makes tennis so challenging is the rapid deceleration and acceleration that's required for you to be good at the sport," explains Ben Boudro, CSCS, owner of Xceleration Fitness in Auburn Hills, Michigan. "The ball movement is very unpredictable and when you have unpredictable requirements, you challenge your brain and muscles to contract as fast as possible to move your body and get in position." Doing this for just five minutes will put a serious tax on your body, and doing it for an hour could burn upwards of 728 calories for a 200-pound person. "If you're looking to get even more caloric burn from tennis, consider adding in lightweight compression shorts or weighted vest," suggests Ryan. "Working out with just 5–10 pounds of added weight can enhance your workout significantly." As a bonus, tennis balls come in awfully handy beyond the court.

8. Flag football

Workouts-That-Burn-the-Most-Calories,-According-to-ScienceJoe Belanger/shutterstock Because it's a common pick-up game that most people play recreationally, it's easy to forget how great of a workout flag football can be—burning 728 or more calories an hour! The field may be shorter than regular football, but with less players in the game (and less hitting) most people run even more. "Coupled with change of direction and hand-eye coordination, flag football truly combines a great way to have fun with friends during a whole body workout," says Ryan. To up the workout ante a little more, opt to play receiver on offense or cornerback on defense, as these positions will leave your lungs gasping and body burning far more than playing quarterback or lineman.

9. Basketball

Workouts-That-Burn-the-Most-Calories,-According-to-SciencePKpix/shutterstock If you want to be good at basketball, you better be able to move and move often. The sport consists mainly of players running, followed by short bouts of sprints and all-out jumps from one side of the court to the next for an hour or longer with minimal breaks. "These all-out movements seriously tax your body and force you to use energy systems that are used in everyday activities," explains Boudro. "Couple those movements with competition and a hot gym and you're definitely going to be burning a ton of calories within minutes." In fact, basketball is known to burn upwards of 728 calories an hour for a 200-pound person! Start off by playing for 15 minutes and build up your tolerance from there, Boudro suggests. Be careful with this one though, as way too many injuries happen in the sport, often because individuals aren't prepared for that kind of impact on their body. Start slow and work your way up, he says. Need motivation? Try these 11 tricks to get moving again.

10. Rollerblading

Workouts-That-Burn-the-Most-Calories,-According-to-ScienceElya Vatel/shutterstock Rollerblading combines a healthy balance of cardio and strength training, without placing too much impact on the joints. Similar to skating, rollerblading involves the use of quite a few muscles at once. "The data for a 200-pound person indicates that 683 calories per hour are burned at moderate intensity," says Ryan. "But to engage the upper body even more, consider adding in some dry land ski poles, which in essence transforms this into a summer version of cross country skiing." Also, adding in several short bursts of sprints for 10–20 seconds at a time are not only fun, but a great way to jack up your heart rate for even higher amounts of calories burned. These are the signs it's time to switch up your workout—and maybe try rollerblading!

11. High-impact aerobics

Workouts-That-Burn-the-Most-Calories,-According-to-Science Lucky Business/shutterstock Jane Fonda is proof that aerobics can be both fun and seriously beneficial when it comes to burning calories and toning muscle. "High-impact aerobic movements challenge your body and muscles to really contract and release in a fast, yet controlled, manner," explains Boudro. The term high impact refers to activities where both feet leave the ground, such as jumping jacks, plyometric style hopping movements, some dancing, etc. While this form of exercise is often fun and allows for a lot of variety, the impact on the joints is not for everyone. "This type of exercise can be made more intense by adding in weighted equipment, keeping the intensity level high and doing exercise that specifically works the large muscle groups such as the glutes, legs, chest and back," says Clayton. "This type of training done in a high intensity interval training (HIIT) style, where you do timed work to rest intervals, can increase the overall calorie burn dramatically. It's important to note, however, that when working out at a high intensity, a shorter overall workout duration is important (ideally lasting 20–30 minutes). Try these hacks to make your workout more fun.

12. Racquetball

Workouts-That-Burn-the-Most-Calories,-According-to-ScienceAlter-ego/shutterstock Similar to tennis, racquetball is a very intense form of exercise, burning upwards of 637 calories an hour for the average adult. "You might not think so because it's mainly old guys playing this at the gym, but if you try it, you'll notice instantly that it is very challenging, mainly because you never sit down," says Boudro. "With such a small court and a bouncy ball, you have to be constantly cutting, running, jumping, and lunging to get yourself in the position for the ball." But perhaps the best part about this sport is how challenging it can be both mentally and physically. Get some buds and start by playing for 30 minutes. Still feel good? Play for one hour!

13. Backpacking

Workouts-That-Burn-the-Most-Calories,-According-to-ScienceDudarev Mikhail/shutterstock Carrying a backpack on a hike or climb of any sort is a great form of outdoor exercise, burning around 637 calories for a 200-pound individual. Thanks to the added weight of the bag, you're building muscular strength both in your upper and lower body. "The varied terrain is also great for improving coordination and working the small stabilizing muscle in the legs and ankles," says Clayton. To make backpacking burn even more, consider increasing the weight you're carrying or choosing an even steeper terrain. Don't miss some of America's most stunning trails to hike this summer.

14. Water skiing

Workouts-That-Burn-the-Most-Calories,-According-to-ScienceJacob Lund/shutterstock This surface water sport, which involves balancing on two skis while being pulled by a boat, might look easy, but it's actually a difficult skill. "Part of the workout is getting the position and really leaning back with your core as you press your feet into the water," explains Boudro. "With your arms constantly contracting by pulling the rope, you'll be working your forearms, biceps, and lats as your quads and calves are simultaneously contracting." Depending on whether or not you go with one ski or two skis, your quads and forearms will be on fire after just 30 seconds of waterskiing. To make this into a more intense workout, Boudro suggests setting up a course to run through or simply timing yourself and attempting six rounds at three minutes each, with constant carving in the water.

15. Rowing machine

Workouts-That-Burn-the-Most-Calories,-According-to-Science Lucky Business/shutterstock While rowing machines may seem old school, they're making a big comeback in gyms and studios across the U.S. "Rowing is a fantastic total body exercise that's low impact but burns a lot of calories with minimal impact on the joins," says Clayton. "The rowing action uses both the lower and upper body, which is fantastic for burning calories at the same time as working multiple muscle groups." As with most cardio exercises, in order to increase the calorie burn, you should do bouts of high intensity mixed with periods of slower paced rowing. This is easy to do now that most rowing machines allow you to adjust your resistance. Clayton suggests doing 60 seconds of rowing at a high speed and and 15 seconds at a slow speed. However, you can also do a moderate pace for many minutes straight, which can be a great steady-state exercise for your program. Ready to test your fitness level?
