pulls
 

In one of the videos about pulls, Sam mentions using the tips of the fingers to slide down the bone of the arm to the wrist. Can anyone tell me what purpose and advantage this has?

That's a good question. I've always just taken it for granted.

I think in part it's training 'bone tracing' for chin na.

I believe that there is also a pressure/meridian point at the wrist that Sifu engages when doing this that apparently is quite painful and/or disabling.

Hi,

I think it also has to do with recognising the structure.
