SO nylon strings are the go.
Tim i know what you mean about real rock climbing or other climbing sports such as rough tree climbing.
Brown urine= lysed blood cells from contusions passing through kidneys?
Cool, or maybe not so cool.
Iron palm is tough on the skin. If you train in hot sand or ball bearings while using the decoction, you will loose your pulse taking sensitivity totally (slap walls instead). The bleeding in urine is probably due to the large amount of aconite in the formula.
Hmm I know that different schools have different systems of steel hand. I remember in wing chun there was sand and ball bearings, but that wasfor finger developing.
IN my system we first start with a bag full of soy or mung beans. Then we progress to a bag with ball bearings, and finally rubber. The ultimate however is said to be using water as an iron palm developing tool.
MAkes me think though there must have been many herbal/acupuncture practitooners who also practiced such skills and had to decide how to balance between healing and martial study.
We do not actually use the dit da jow until the the latter stages of training, i think this is because of special exercises we do before hand which actually promote hand strength, flexibility, and qi pressure. WIth bleeding i have heard this happen in systems that both use dit da jow and those who dont so i am thinking it must be due to the lysed blood cells.
Don't soak hands if you have any cuts. Better still, train brain or heart (outwit them or love them to death)
INdeed, i think those are more noble and often more effective methods of conflict resolution. However i have been in several places and times where my fellow freinds, and companions, and I were happy that somebody knew the art of restraint or rather restraining others. A martial artist should never use their art for themselves, like you said Mark, using the brain and heart are superior, i think it is reserved for when dialogue has ended and people are only speaking with their mid brain.
The reason i am doing steel hand is actually because i have found it increases my pressure in various other exericises I am doing to develop speed, power, and snapping energy. PLus I want to snap a pebble with my fingers, that is cool
