> So taekwondo people who train to hit concrete pillars don’t get stronger from the repeated hits, do you confirm?

Stress from repetitive microtrauma is not the same as a fracture (stress to failure). Increased mechanical loading (hitting a concrete pillar, exercise) can absolutely strengthen bone in a similar mechanism to decreased load weakening bones (little old lady, astronauts).

Breaking a bone completely disrupts the internal architecture and what is deposited is unequivocally weaker than what was there before.

> And “what doesn’t kill, makes you stronger” is false too

I have no professional opinion on this aphorism. I do have one on bone healing.
