This is part of our previous SKD session last Sunday.
The development of striking skills begin with bigger movements rather than smaller movements.
Why we begin with bigger movements is because it is easier to feel what we are doing. It is also easier to develop power through a bigger motion.
When we can feel what is happening, example how our arm is moving relative to the waist, how our legs is assisting the swing by coordinating the rise-fall movement that allows us to use gravity to accelerate down and use the same movement to come up etc, then its time to work on reducing the size of the movement.
A smaller movement is faster and is more useful when used for probing and entering.
