Medball aerobic work: east Europen throwers?

I heard someone speak once and they mentioned in the past some eastern european throwers would use med ball routines to help develop endurance without pounding on the legs. Anyone know anything about this and if there are any resources available (sites, articles etc)?

You mean extensive medball? How about this:

or the GPP download?

It wasn’t a thread. It was a conversation I had with a coach. Thought someone might know something about it. I have both of those products.
