Any good Japanese bodybuilding forums on the net?
 

I already know many good forums about bodybuilding in English and other European languages. But I didn't find any Japanese one.

Anybody who could help me out?

Nope, lifting alone is not enough. You have to eat as well.

In a bodybuilding forum there will be many good recipes for Japanese style high protein food, which I'd like to try out. :p

And I could easily learn how to express things like "whey" and "Anabolism" in Japanese.
