Where is the proof that 'Bone Conditioning' isn't BS?
Until someone proves otherwise.
And by "prove" I don't mean "Anecdotal story about a guy punching something hard"
I don't mean unfounded assertions about thick bones based on alchemy from the year 1000 bc
I don't mean ads for or arguments over the properties of any stinking lotion that don't have some sort of proven scientific validity
I don't mean references to something in a language no one reading speaks
I don't mean solo experimentation uncontrolled for other factors - ie the value of exercise, the conditioning of skin vs bone, the natural starting density of the person's bone, the effects of secondary exercise such as weight lifting, etc.
I also, before conceding that bone condition is not BS, demand someone show both that it actually occurs, that it actually occurs from the specific training in a given bone conditioning regimen, and that it does so in a manner and amount that somehow adds combat effectiveness.
Also, while you're at it, it wouldn't HURT to categorize the number of hours it takes to achieve these effects for comparison to other, less BS methods of training.
Will anyone rise to the challenge of finding or making the science to test the hypothesis, "repeatedly striking surfaces at escalating levels of force eventually produces a change in bone structure useful in a martial arts context" and associated specifics, or will this thread sink like a fucking stone?
