Enter your weight, training duration, intensity level, and training type to find out how many calories you burn in BJJ or grappling. You'll get your total calories burned, an estimated calories per minute rate, and a breakdown comparing different intensity levels.

Most practitioners burn between 400 and 800 calories per hour of BJJ training, depending on body weight, intensity, and training type. A 80 kg person doing moderate mixed training burns roughly 550–600 kcal per hour, while hard sparring can push that closer to 700–800 kcal/hr.
Yes — BJJ is one of the most effective martial arts for fat loss. It combines high-intensity intervals during sparring with lower-intensity technical drilling, creating an efficient calorie-burning session. Training 3–4 times per week can create a significant weekly calorie deficit when paired with a sensible diet.
BJJ sparring burns more calories than jogging, swimming, or basketball for the same duration. According to MET data, competitive martial arts sit at a MET of around 10–12, compared to 8–9 for running at a moderate pace. The stop-and-go intensity of rolling makes it comparable to HIIT training.
Yes. The high-intensity nature of grappling creates an EPOC (Excess Post-exercise Oxygen Consumption) effect, meaning your metabolism stays elevated for hours after training. Building lean muscle through regular BJJ practice also raises your resting metabolic rate over time.
Competition burns significantly more calories than regular training — estimates range from 600 to over 1,000 kcal per hour due to maximal effort, adrenaline, and the physical demands of back-to-back matches. This calculator uses a higher MET value for competition to reflect that intensity.
MET (Metabolic Equivalent of Task) values vary by intensity: light flow rolling uses around MET 5–6, moderate training around 7–8, hard sparring 9–10, and competition-level effort 11–12. This calculator applies blended MET values based on your selected training type and intensity level.
Heavier athletes expend more energy to move their own body mass, execute takedowns, maintain pressure, and escape positions. The standard calorie formula — MET × weight (kg) × duration (hours) — directly scales with body weight, so a 100 kg grappler burns substantially more than a 60 kg grappler doing the same session.
This calculator uses established MET-based formulas, the same methodology used by sports science research and fitness apps. Results are estimates — actual calorie burn varies based on individual fitness level, muscle mass, rolling style, and rest periods. For precise tracking, a heart-rate monitor provides the most personalised data.
