I was fortunate to attend a seminar recently by Kubota Ikuhiro Sensei. He spend quite a bit of time teaching various kata for improving one's ashi sabaki (foot movement). Having been to a number of seminars by different sensei, this is the first time I have encountered such exercises in Aikido... although I know that some of the sword schools have specific exercises for ashi sabaki.
Does anyone have more information about exercises for ashi sabaki?
Hiroshi Tada has a whole load of exercises and spends at least one third of any seminar teaching them. He starts from shizentai (natural posture with the feet side by side slightly apart) and goes into hamni and the movements go in eight directions, starting from either foot. You can imagine all the combinations. He regards this training as absolutely crucial to the success of any partner practice.
