At what point is max. strength improvement not neccesary?

I don’t think I’m the only one making assumptions, but I really don’t have any “lifting” assumptions based on 100 times. There are things with body types that can be general indicators, but they are not always true.

Also, I just don’t think Bolt should be used as the standard for what every aspiring sprinter should be doing. Bolt or even Powell is fast without this or that = making it true for everybody. Even the D3 guys you picked out, that is impressive, but in the end not sure what that proves if anything.
