Jodan, chudan, and gedan in the martial arts- high, medium, and low.
When practicing kamae (martial arts postures) we often start at the jodan- high level.
Move into posture, receive an attack with taihenjutsu and apply waza.
Some of the more traditional forms of kata have us sitting in seiza or fudoza- gedan level in practice.
But what about chudan?
That mid level?
Practicing kamae from sitting on a bench or chair.
Strikes and locks from moving out of the seated position and into the seated position.
Using the stability- the physical stability of the chair or bench to add momentum to the technique.
Adapting the vertical levels- you might be seated at chudan, but your training partner standing at jodan level.
What changes and is dynamic in the movement?
