KEEP WEIGHT UNDERSIDE

Keep weight Underside, meant placing the entire body weight on the bottom, meaning the feet, so the foot of the focus areas is the 'balls' which close to the finger toe.
So, it will look like 'tiptoe' but did not tiptoe. All the foot remains in contact with the floor or ground.

By this way, foot movement to go forward, backward, will be lighter and faster, gliding, of course after properly trained. But do not forget the principle of "Keep one Point", which has been described earlier.

We can train it by Tenkan and Ibodashi also in 'ashi-sabaki' (footwork).
In Training with Tenkan, we do tenkan continuously so that we as a whirling.
Initially will feel dizzy. If the head feels dizzy, this indicates we forgot the 'Center' or 'One Point" and also we do not breath regularly/ properly. So, if felt dizzy, immediately set breath and return our center.
In addition, when moving, Kamae position must be stable, not 'up-and-down', assuming that above our head is concrete-roof.

At least, this exercise tenkan around 30 counts, and then increased to 50 count and so on.
With this practice as expected, we can know more about one-Point/center and put weight on the balls of the feet, and maintain the balance of the body.
