My Sihing and I were the only ones in our class to train body conditioning regularly. We used long and short jin for this.
He later relocated to LA and trained under another teacher. On one occasion sparring a larger classmate, his opponent grappled him for a shuai chiao throw. My Sihing used the short force kao da and knocked his opponent to the ground.
His teacher pointed at him and silently shook his head to tell him not to use that on his classmates.
Short force is a good skill to train.
Sure, you can cut and paste as you like to twist as usual.
Since you are from WSLVT, is your Wck similar to the type use by Obasi opponents here?
