Should i be a sprinter or a judoka?

Well you are asking in the martial arts section so you will probably get more Judoka answers, but really which ever one of these that gets you up in the morning to train with everything you have and it feels worth it at the end of each day, it takes a lot more than jus ttalent to reach Olympic level it takes pion for the sport and total dedication. Good Luck on which ever path you decide.
