[General] How could bones be altered to be stronger, have higher tensile strength, and generally higher durability WITHOUT making them heavier?

how much stronger? How much of an increase in tensile strength and durability?

The least invasive way would be to genetically modify the osteoblasts to lace the bone with carbon nanotubes - making the bone into biological high strength carbon fibre.
