sup guys? i've been doing a 45 min. kickboxing class for about 6 weeks 3-4 times a week.today i went to elsinore mx and rode longer than ever with out getting arm pump . i used to get pumped up in about 2 laps.and was able to not get winded or tired . i rode for about 30 min straight @ better than avg. speed ,took a 10min break to drink some poweraid got back on the track went for about 45 min before i ate a plate of s@#$ casing a jump then i went home. i wasn't even tired i just bruised my cankle so i left. i highly recommend a kickboxing class to get your cardio in check.
but the kickboxing is way harder than riding
