Old School Training Methods

[YoungOne]

What were some old school methods for reaction timing, and please post any other old school training methods you know of.

Not sure specifically for reaction timing. That all comes through sparring.
But, some people, like Kosta Tzyu and i think Pacquiao used to do it, Is there trainer throws ping pong balls at them and they have to dodge them. Sounds easier than it is.
