So endurance,cardio, and VO2 max all go together without saying,and I have the best of all of those on my team by far...but its not enough,i want to be able ot sprint (literal and metaphorical-wrestling speaking) for 6 minutes straight without feeling a sweat....what are some good ways to build up to this? I do a lot of HIT training at the gym-lot of time doing intervals on jump rope,taking a shot into sprints back and forth,running a halfmile in between sets of jump rope....I just need to be able to make my opponent break fro exhaustion before I even think about sweating...thanks in advance...
