I'm sure soke has his reasons, as did Musashi for his students.
Iām sure Musashi said that wielding a katana is always difficult, but in time it gets easier. I strengthen my radius/ulnar deviation with one of these handles on the cable machine.
It really improves oneās katateuchi (single handed cuts) and makes oneās forearm ruggedly gnarly!
But yeah I'd love to train Niten with a heavier bokuto eventually, for exercising if nothing else.
See above.
My worst form is shomen uchi - it frustrates me to no end! I tend to chop rather than slice, and don't extend my arms up and outwards enough,
I had the same issue until a teacher suggested standing with the sword above oneās in kaburi with oneās arms
fully, 100% stretch upwards! Then bring that extension
down to 90% and try cutting from that position with the feeling of using the
very tip of the sword -snipping with the kissaki! It really helped me. You could also try one of these golfing straps to help keep your arms straighter and coordinated together initially at least.
and my strike is either followed by my body or my body is followed by my strike.
Forgive me for offering unsolicited advice but hereās a great exercise for āki ken tai ichiā if you want to try it.
1) Place your drawn sword on your right shoulder (mune resting on it, obviously

).
2) Then stand on your left leg only.
3) Lean forwards and as youāre falling forwards step out with your right leg and simultaneously lift your sword above your head (remember the 90%,stretch).
4) As you pull up the left leg in hikitsuke begin cutting so it stops as you left foot stops just behind your right heel.
This will give you the
exact feeling of ki ken tai ichi! When youāve internalised that feeling, you need to move in the same way on both legs!

The advanced, ultimate movement is to begin and finish cutting in the last
third of the left foot hikitsuke. Give it a tryā¦itās actually great fun.
