Hi first time poster I currently take Goju karate,and my Sensai has recomended that I don't cross train untill I get to black belt or higher. I can understand this because I dont wish to have the styles mixed, I want to learn them at my own pace. But out of curiosity (and for my future desicions) I was wondering what other styles you feel "compliment" goju karate. This is my first style so I dont know what the others are like but a few things I was considering. Judo- from my limited knowledge judo involves many grabs/takedowns and fighting on the ground. I think this would be usefull because I find myself on the ground alot while sparring. Ninjutsu- I have bassicly no knowledge about it but it looks really cool. If someone could give me more information on it I would be very gratefull. Zui Quan- From what I know this is drunken boxing, and I would love to get to know this art better. I like to be very unpredictible when I spar, so this might help improve that. anyways I am still learning about these things, but I would like to hear your expiriences with them, any strengths they have, and how easy it is to get into said schools.
