Descriptions of the Aiki-taiso from Rod Kobayashi-Sensei:
12. Enkei Choyaku Undo
Stand naturally with your arms at your sides. The "One" count has you look(and turn your hips) left, cross your right foot behind your left, then take a large step to your left with your left foot and dip at the count "Two". Execute the Enkei-undo while you are doing this exercise.
Alternate left and right and repeat this exercise several times.
This movement helps you to keep your balance as you move with a pull at your wrist from the side so that you can move well within your range of effectiveness.
