Icetuete

hey everybody! my name is bernd and i am 17 years old. i think of learning a martial art and so far the best choice seems to be taekwondo. most important to me are the mental aspects and physical fitness. in how far is TWD better at these aspects than other martial arts? according to which criteria shall i choose an association? are there certain exercises a beginner could do at home to prepare for training, before i REALLY begin with a martial art? what equipment do i need? hope u can help me!!
