Martial Arts Calories Burned Calculator: Boxing, BJJ, Muay Thai, Tai Chi
See roughly how many calories your boxing, BJJ, judo, Muay Thai, kickboxing, Krav Maga, Wing Chun or tai chi session burns, based on your body weight, intensity and minutes trained. Built on the Compendium of Physical Activities. No email needed.

Estimate calories burned in martial arts
Pick your art, how hard the session was, and how long you trained. The math uses MET values from the Compendium of Physical Activities, the same research tables exercise scientists use.
Your estimated burn
The breakdown:
Same time, other arts (typical class):
| Activity | MET | Calories |

A hard class on the mats or the bag pulls out sodium along with water. A sugar-free electrolyte mix is an easy way to replace it.

How to Use the Martial Arts Calorie Calculator
Enter your body weight in pounds or kilograms, pick your art, choose how hard the session was, and add your minutes on the mat or the bag. Be honest about intensity. Most classes mix warm-ups, technique and a few hard rounds, which is what the Typical setting is for.
Each art and intensity maps to a MET value from the 2024 Adult Compendium of Physical Activities, the research reference for the energy cost of hundreds of activities. Where it has a specific entry, like judo, boxing bag work or tai chi, the calculator uses it. Where it does not, it uses the general martial arts entries.
The formula is the standard one: MET times 3.5 times your weight in kilograms, divided by 200, gives calories per minute, multiplied by your minutes. Every result is an estimate, so you also get a realistic range of 20 percent either side and a side-by-side table of the other arts.
I have trained in seven martial arts: Wing Chun, tai chi, boxing, Brazilian Jiu-Jitsu, judo, Muay Thai and Krav Maga. I have also taught kids’ Krav Maga-based self-defense and adult beginner Wing Chun and boxing classes. In any class, the biggest difference in calories comes down to how much of the hour is spent moving.
Three Truths About Martial Arts and Calories
Rest between rounds changes everything
A one-hour class might hold 25 minutes of hard work. Count the whole class in the minutes field, pick Typical, and the estimate already allows for the slower parts. Pick Hard only when you move almost nonstop.
Striking and grappling burn differently
Bag work and pads come in bursts that spike your heart rate. Grappling arts like BJJ and judo feel slower but keep big muscles working under load the whole roll. Both count, and both build fitness a treadmill cannot.
Tai chi is not about the burn
Tai chi burns far fewer calories than sparring, and that is fine. Its real payoff is balance, leg strength, calmer breathing and joints that move better. Pair it with walking and strength work if fat loss is the goal.
Martial Arts Calorie Questions, Answered
How Many Calories Does Boxing Burn?
For a 150 pound person, an hour of steady heavy bag work burns roughly 600 calories, and full-pace ring rounds can push past 850. Lighter technical bag work is closer to 400. Your weight, pace and rest time move those numbers, which is why the calculator asks for all three.
Does BJJ Burn More Calories Than Muay Thai?
In the research tables they land in the same range, because both fall under the same general martial arts entries. In real life it depends on the class. A BJJ class with lots of live rolling and a Muay Thai class with nonstop pad rounds both burn roughly 550 to 750 calories an hour for a 150 pound person.
How Many Calories Does Tai Chi Burn?
A standing tai chi or qigong class burns roughly 240 calories an hour for a 150 pound person, based on a MET of 3.3. Seated tai chi is about half that, and long, deep-stance Yang style practice comes close to double.
How Accurate Is This Calculator?
It gives a reasonable estimate, not a measurement. MET values are averages from research on many people, and your burn depends on fitness, skill, rest between rounds and body composition. Fitness watches estimate too. Use the number to compare sessions over time, not to earn food back.
Can Martial Arts Help With Weight Loss?
Yes, as part of the bigger picture. A few classes a week add real calorie burn, build muscle and keep training fun enough to stick with. Fat loss still comes mostly from eating a little below maintenance, so pair your training with a calorie target from my TDEE calculator.
Why Do Krav Maga and Wing Chun Use General Values?
The Compendium groups most striking and self-defense styles under general martial arts entries instead of listing every style by name. So Krav Maga and Wing Chun use the slower-pace and moderate-pace martial arts values. The intensity setting matters more than the style name anyway.
