Re: Training TKD/Karate while taking aikido?
I think that the issue in cross-training in martial arts has more to do with finding similarities in the "operating systems." If one system is teaching to respond with a lot of muscular contraction, while another system is teaching you to respond with a relaxed and connected body, then you might be in for some trouble. You cannot be in two places at once. That being said, most high level instruction in many martial arts have similar (if not the same) underlying, operating systems. I am currently training in Aikido under Imaizumi Sensei, Shindoryu Bujutsu under Ushiro Sensei, and "IP" (for lack of better initials) with Dan Harden. Each of them complement and inform the other and result in my becoming better across the board in my budo/bujustsu abilities.
