5 days until my tourny and my main concern is my cardio. do u think 5 days is enough time to improve my cardio at all without losing weight? I am 135 exactly and i would like to stay there so i can match up against some bigger guys. (if i lose a pound i drop a weight class). So i was just wondering if there is any way to improve my cardio by then without just wearing myself out and being drained the day of. If not its cool i can just start working on it afterwards, but if anyone has any tips im all ears.
