Yeah, the title says it all, how should I improve my stamina/cardio for BJJ? What are some of the most effective ways to do it? My goal is, while sparring, I wanna be able to be very explosive and keep the fight going at a fast pace the entire time, I wanna be pushing the pace...how would I get my cardio to this level? Opinions, and words of advice would be very much appreciated, thanks guys =)
