Hello guys, I'm 5,5ft and 181lb. But I'm not fat, my body is rather bulky (i'm not doing gym by the way). I'm very used to cardio exercises as I'm a pro in badminton. But I know that I can't be very flexible and swift, my agility is average and i'm pretty powerful. So what should I choose I have these options around my home: taekwondo, karate, aikido, judo, muaythai, vovinam, kickboxing, aikibudo. I want to train and stick seriously but I don't want to change my body (ex: become thinner). I imagine myself to be strong and tough, not really needed to be fast or flexible that is just my imagination I really need advice. Thank you very much!
