same as any other martial art mate, mix it up, if you want good aero endurance 800 meter sprints (work up to that) works well.
something like 4 X 800. throw in a couple of short sprint days such as 8X100 meters and one long slow ( active recovery) session.
that would be reasonable, but work up to it, start 3 times a week. 1 of each and lower reps.
thats my advice anyway. there are other good ways too.
hope that helps and good luck with your training.
