Stretching Excercises for Iaido

***Can anyone tell me what are good stretching excercises for Iaido?...Also I have size 12 feet..How can I get my toes to bend(As in on the balls of my feet) when performing cuts?..My feet and toes seem to be to long and see to twist to the outside when I try.
Thank you,

Although my knowledge of Iaido is limited (one book I have read on the subject) I feel that you would greatly benefit from Hindu squats.

Go to http://www.stadion.com/column_stretch22.html and it will describe better than I can how to do this exercise.

It will not only build flexibility into your toes but in your knees and legs as well as strenthening them (no more aches and pains after sessions!)

Try them and let me know how you get on.
