Hello,I am new to this site and I'm sorry if this sounds repetitive.I am 30 years old and I am looking for a karate style to study.My 3 options are chito-ryu,goju-ryu and wado-ryu.I was wondering which, if any, of these styles include roundhouse kicks in their teachings.I would also like to know which of these is most physically demanding(I love a good sweat).And my last question is,which of these styles is more suited to competition(sparring)?I would greatly appreciate any feedback.
