setpro in and of itself is not a “program.”
yes, Nyman came out with a backwards chaining progression and a weighted ball program. But just as important as the actual programs themselves are the ideas and concepts that form the basis of these programs.
I’m not going to try to get into the mechanical part of setpro and throwing (not that I 100% fully understand it or will ever) because that would not really be possible in this format
but some ideas:
weighted ball training works if done properly.
a player must be very very well physically trained to help prevent injury. 99.9% of players are unprepared to throw a ball at max effort.
velocity is necessary to reach the higher levels of the game. It becomes less important at the highest levels of the game but if you don’t throw 85+ mph it should be your #1 priority.
there’s more but that’s just a flavor of setpro
