cool...
So you really do them on one knuckle? or do I just have strange hands
You press onto 1 knuckle. You need to play with the position of each hand in the different positions to get more knuckles along the ground. You can't be just on the middle knuckle the whole time.
Same way you train Fung ahn choi, another single knuckle technique.
another idea, start attacking the top of a heavy bag, where its all soft, and work your way down into the harder centre.
like attacking eyes, and moving down to solar plexus.
when i practice CLF i go in to the traditional horse stance but when in a real fight i would use kwa and sow chui and a few boon kius. in a life and death situation i would use fu jaos and eye gouges or phoenix eyes. it was keep a regular boxing stance except my hards vary on the fighter. when doing my sow chuis ill go on a low heel toe horse stance.
