So i've been actively following MMA for about the last year and a half...my friend bought the UFC 68 card and I've been hooked ever since. i've never been in a fight, but i really like watching the different fighting styles/skills/etc. i used to work out some in college but stopped, pretty much don't do any exercise now (unless you count walking 18 holes ), but i've always been pretty athletic. i went to the little store in town this weekend to get some sugar/eggs for the wife, and saw a poster for judo/bjj classes near-by. www.uppervalleyjudo.org i thought it might be fun to try out, but considering i am most likely NOT going to be doing a lot of running/strength training/etc. because i don't really give a shit, is it worth joining? like, if the instructor says "you're doing well, but lifting 3X per week would really help," would i "offend" him if i didn't do anything outside of the class and just showed up on Sundays?
