Re: cross training
Good question! I'm tackling it too right now.
I've been doing aikikai for 8 months, and wanted to extend my studies from twice a week to 4. Since my dojo doesn't offer more classes at evening hours, I added another dojo, with a sensei that teaches Yoshinkan combined with BJJ. The teacher is great but
I find that everything that's right for Aikikai is wrong for yoshinkan and vice versa. The way you stand, roll, fall, even the terminology, everything is fundamentally different.
I sure got a new perspective, but also allot of confusement.
Maybe it was a bad idea?
