Hi everyone, i am planning to start training soon, and there is a great school not too far from my house that teaches judo, jiu jitsu and sambo. I know what sambo is and i basically understand what judo and jiu jitsu are, but i havent been able to understand the difference beetween judo and jiu jitsu. Is judo more focused on throws, whereas jiu jitsu is more focused on floor grappling? Are they both effective for self defense? From what i have read, it seems that jiu jitsu is more effective for defense and judo is more sport oriented, but i havent read much and could be wrong. If anyone wants to check out the school im going to, go to www.gokor.com. Thanks to all for your comments and answers.
