curious if judo is good for self defense?
quick answer is yes.
most fights end up on the ground and for the most part a lot of grabbing and shoving before you go to the ground. once you have a grasp on your opponent you can throw, control or punish him/her.
judo was born out of Ju Jitsu......there are many joint locking and chocking techniques that can be used either standing or on the ground. if you are defending yourself against one person and you are confident that you have "submission" skills (judo or JuJitsu) then go to the ground and work from there. if you are defending yourself against more than one person... RUN AWAY....or, put your back to a wall, stay off the ground and do the best you can.
