i don't remember much, because i lost consciousness several times during my first lesson. i remember lots of screaming, & bleeding a lot. i'll admit, i even cried a little when i got home. i was 24 at the time.
anyway, it's worthwhile if you just stick with it. enjoy the journey!
p.s. i'm just screwing with you, have fun.
while frostbite provides a good cautionary tale, i just want to point out that low cost doesn't always mean it's a crap class. my judo/jujitsu/sambo coach teaches out of a rec center, & has managed to turn out national & world champs, as well as an olympian.
