Well im certainly going to do BJJ for my ground game, im not quite sure what to do for my standup striking game though, im 6"7 and of a much more powerful build then flexible so i think things like kickboxing arent playing to my strengths. Any suggestions??
Trust me, once you start stretching everyday, you will get much more flexible. I don't care how big people are, you can still be flexible. A lot of powerlifters are also Martial Artists, so yeah.
Good luck, man.
