Aikido has both external and internal aspects to its dynamic movements. We study '6 Harmonies' movement principles to develop internal strength as taught by John Burn Sensei, who was the UK's most senior student of Hiroshi Ikeda Shihan before his move to Japan. John Sensei now study’s aikido full time in Kyoto. Moreover, he is directly taught by the renowned internal arts teacher, Mike Sigman. John Sensei regularly returns to the UK to deliver Aikido seminars to our dojo.
Learning internal strength develops a connected body and can improve the martial efficacy of the aikido waza.
Aikido without 6 Harmonies Movement, or, internal movement as Ikeda Sensei would say, is "empty practice and therefore not aikido".
