Crosstraining with Fundamentals

[Bryan Murley]

Hello. I'm sure this question has been asked before, so I apologize in advance.

I currently do crossfit type workouts (normally around 50-70% intensity) as well as train brazilian jiu jitsu 5 times a week. 

I think I would really enjoy the fundamentals class. To see the best results will I need to eliminate other workouts? I really enjoy doing these as well and would like to simply add the fundamentals into this trainingregimine. Rarely do I train hard enough to feel exhausted the next day.
