Training started with a simple shuto.
Start walking and moving the body.
Walking and paying attention to the movement of the legs and the arms- they are moving in unison at the same time.
Further walking, don’t rush the technique.
Paying attention to the length of the steps we take- not stepping so far ahead that our weight shifts and we are out of balance.
When it is time to throw the shuto- stepping at the same time with the leg- the upper and lower half of the body moving in unison at the same time- the entire momentum of the body unified behind it.
The shin gi tai of walking for a bit to really center in and focus (awareness) about this structure point of the body.
