OK I know "three star" excercises are good for building up your bridges in hung-gar, and that strong bridges can be a painful deadener of arms. There are also the limb destructions for attacking the nerves on the inside and outside of arms with more precision though, such as with the fist. Do any of the core forms of Hung Gar like Taming the Tiger or Tiger/Crane illustrate any of these kinds of limb (esp. arm) destructions?
