I thought this was interesting, not so much the power of the impact (as this would be next to impossible to use on a moving opponent) but the idea of conditioning bones. What are your thoughts on 'hard body training/ wolf's law? I know that it probably takes a long time to build yourself up (time that could be used training useful techniques). Could this kind of thing be useful if trained for a short time each day to maybe strengthen hand bones?
I watched that video. I've seen things like that for years. Sure, one can add calcium to their bones to make them harder... but is it really worth it? Opinions vary of coure. Personally I feel that if you aren't going to be a pro figher, fighting and striking in the ring on a regular basis then it is not worth it to put yourself through all of the pain it takes to injure your bones little by little and add calcium to them. A good example of this would be to spar with either of those guys on that video. I feel pretty confident that I could out kickbox them standing, beat them in the clinch, and submit them on the ground. Not just me... but any descent MMA fighter. I have sparred with wing chun guys who have spent a lifetime doing hard body training and can do some interesting or impressive things with their bones, but they are severly lacking in the sparring and grappling actual ability area. That in my opinion, is deffinently not worth the sacrafice.
Lots of people in the martial arts are into lots of things other than realistic sparring and grappling, and their realistic combative ability suffers greatly because of it. Some people are into bone hardening, body building, chi power, no touch knockouts, etc... but all of it is about as valuable as ballroom dancing for application in a real fight against a fully resisting opponent. You cannot substitute or beat realistic training. Now if you have enough time left over after that for other training types, body (cardiovascular) conditioning and weight training should be the next things on your list. Body hardening (adding calcium to your bones) is pretty low on my list. Without it you can still eye gouge, palm strike, elbow, knee, and kick on the street and punch in the ring with NHB or boxing gloves on. I don't advice ever punching in the street, even with bone hardening, due to the very small size of our hand and finger bones.
I have no plans to start bone hardening training. I wonder what kind of long term effects that kind of thing has. I am almost 29 and over-all-health/longevity are becoming priorities in my training (I have not had much time to train lately because I am lazy and I am in Graduate School). I think that with any combat sport there are risks but I am not going to be purposely altering my bones. I agree with what you said about priorities. I do find what the human body can adapt to fascinating.
