Speaking of tae-bo.... my ex used to do that shit and I thought it was dumb.... until I did the advanced workout one afternoon just for the fuck of it.... that shit is actually a pretty good workout and it's kind of fun. I'm a 4th degree black belt in Korean Tae Kwon Do and have a black belt in Aikido and in Jujitsu and I can honestly say that it is a well-put-together little program for a commercialized fitness video.... but I wouldn't count on it saving your life or keeping you from getting your ass kicked ....
