I also requested everyone else on the forum answer these questions too, I'm curious about their Aikido backgrounds and any other training they have received. So I'll share mine.
I practice Aikido Yuishinkai, a branch off from Ki Society. Only recently, due to some great advice from Tony and my own father, that I start taking Aikido seriously and train in a more serious and curious manner. I have only practiced Aikido but have had suggestions to take up Judo to further understand balance breaking and the such. I also hope to take up Kenjutsu or another sword art to better understand the weapons side to Aikido.
Keen to hear others.
I am pleased that you have decided to study Judo. All the best teachers that I have ever studied with came from Judo to Aikido. These are not teachers that I have attended a seminar with, but studied long term.........Kenshiro Abbe Sensei ~ Tadashi Abe ~ Masahilo Nakazono ~ TK Chiba....It will be good for you. I too came from Judo to Aikido in 1957.
