For anyone who enjoys a good workout or wants to protect themselves better I highly recommend doing jui jitsu or boxing but mostly jui jujitsu. Jui jitsu teachs you to be more flexible and to work smarter not harder by focusing on technique. I wrestle and fight my friends all the time and it gets pretty intense and 8/10 I win because of me knowing more jui jitsu thank to more ways to break someone's arm than any striking could teach me. For example my friend who is 320 pounds and 6ft 5 inches I fought him yesterday day and tapped him so many time just by getting him a kimura lock.
