it looks good so i thought i’d give it a shot, i’ve heard mixed things about it (some don’t like watching it, others prefer other martial arts like jiu jitsu)
Try it out for a week, most schools will let you do that. If you like what you see, you like the other students, and you like the instructor, then try it for 3 months and reevaluate then. I recommend trying many different martial arts. Just don’t let them give you a hard sell and sign you into a 1 year contract! Whatever you do, don’t choose just one martial art and do only it for the rest of your life!
Why do you want to train martial arts? Without a goal it’s hard to tell if TKD can be for you. Is it impressive? Athletic? Sure. For me personally I’m not a fan of the focus on kicks that is due to the WTF ruleset. Why? I like to also punch, grapple, throw, do weapon work etc. and even if self defense is totally not in my focus the high kicks, lack of a proper guard etc. are not for me.
