3 weeks till tournament

i have 3 tournaments comeing up in 3 weeks. 2 of them in the third week then the other on the next week.

i train 6days a week 2 hours a day. i want to get more endurance/strength. i rather work more on the endurance because i don't think 3 weeks is enough time to get stronger. would doing intervals & bwe be a waste of time? or should i just stick to rolling in class?

woops i ment to put this in the strength & conditioning fourm. moods feel free to move or delete
