Re: Home Practice?
Here's what I do with the bokken (a heavy suburi bokken):
gentle cuts to warm up
50 cuts with right foot forwards, but stationary (shomen or yokomen)
50 cuts with left foot forwards, but stationary (shomen or yokomen)
50 cuts stepping either side of the centre line
50 cuts stepping either side of the centre line but using the uchi komi motion ('blocking' motion)
repeat last two sets of 50 cuts.
Extension exercise with arms (stretching gently in front)
Do these one straight after another
If you do this every morning (may be hard at first), your aikido, back muscles and cutting strength will improve, as well as your wrist strength.
Catching bricks (arms out in front, throw house bricks up and catch with fingers) x 80 is also good for developing grip strength. (old wu chi exercise)
