Estimate calories burned during Brazilian jiu-jitsu from body weight and session length, with class breakdowns for warm-ups, drills, and rolling.

Estimate gross energy, including resting energy. Default 8 MET is a whole-session assumption, not a measured BJJ standard.

1 MET approximates resting energy. Account for breaks in the session average.

Optional weekly estimate

Optional. Blank omits the weekly estimate; fractional averages are allowed.

BJJ Calories Burned Formula

This calculator estimates gross energy, including resting energy, using MET intensity assumptions. The basic default is 8 MET; breakdown defaults are 4 for warm-up, 6 for drills and 10.3 for rolling. These are adjustable proxies, not measured BJJ standards. The Adult Compendium lists 10.3 MET for general moderate-pace martial arts, including jujitsu, and applies to adults aged 19–59.

Gross kcal = MET × 3.5 × Body Weight (kg) ÷ 200 × Minutes
Total Gross kcal = 0.0175 × Body Weight (kg) × (Warm - up MET × Warm - up Minutes + Drilling MET × Drilling Minutes + Rolling MET × Rolling Minutes)
  • Body weight may be entered in pounds or kilograms; 1 lb = 0.45359237 kg.
  • Session minutes are the entered duration; choose an average MET that accounts for rest. Results are estimates, not personal measurements.
  • Under the default assumptions, rolling has the highest estimated energy rate. Actual segment intensities may differ.

How to Use the Calculator

  1. Enter your body weight and select pounds or kilograms.
  2. Choose Basic estimate for session duration and average MET, or Class breakdown for warm-up, drilling and rolling durations. Blank segment times mean zero.
  3. Click Calculate to see calories burned.
  4. Optionally enter equivalent sessions per week in either mode. In breakdown mode, intensity assumptions can also be adjusted. Blank weekly frequency omits that estimate.

BJJ Calories Burned Per Hour

At the assumed 8 MET intensity, estimated gross energy rises with body weight. These 60-minute examples use the defaults:

  • 150 lb: about 571.5 calories
  • 175 lb: about 666.8 calories
  • 200 lb: about 762.0 kcal
  • 225 lb: about 857.3 kcal

What Changes Calorie Burn in BJJ?

  • More time at higher intensity generally increases estimated energy expenditure.
  • Class structure, breaks, individual physiology and skill affect energy expenditure.
  • The model does not measure rest or intensity automatically.
  • With the default 10.3 and 6 MET assumptions, rolling is estimated at about 72% more gross energy per minute than drilling. This comparison changes when the MET values change.

Example

For a 150 lb athlete in a 60-minute BJJ class:

Gross kcal = 8 × 3.5 × (150 × 0.45359237) ÷ 200 × 60 ≈ 571.5 kcal
