Simple! I explain.
Most likely in a regular moderate Jiu Jitsu class you can burn up to 1.200 calories. More with you a really mind set person. The reason why is the secret in Brazilian Jiu Jitsu: your body is in constantly move. All time. Every time. No matter position you find yourself you always will do a synergy of moves attach to isometry and cardiovascular exercises that will lead to a amazing exhaustion by the end of the class.
Important note : you always gotta have a class with a supervised instructor.
To start off you should do a 10-15 minutes mix of cal-esthetics Stretching and Cardio. All are valid! Don't force yourself too much just because you have a number of calories to reach by the end of this report.
Don't be foolish. Average student spend a good 15 minutes of warmup. Follow up 10 minutes drill. Right there is you are not a persona that every time drink water, the possibility of burn more will attach.
Be a moderate Water Drinker. Don't get your belly full!!!
After that a good sparring sessions of 4-6 minutes will lead to a sweaty body. Respect your limit. Respect your body. And always respect your teammate. So you don't get hurt and can keep up with the whole group.
Sequence to be follow...
