Whew! they really push the pace versus my Bjj classes. i mean fuck, every thirty seconds was a new drill. I had a very very hard time keeping up. Even hurt myself a bit. Fucked up my ankle kicking the bag wrong with my left leg when i got tired, huge bruise on the ankle bone. Ripped piece of my toe nail off too. Christ almighty. But it was soooo goood... Tomorrow will be a hurtful day i think. My body is sore as fuck.
