I agree with the coach comment, but beleive that all throwers should become students of their event. If you are a thrower, you need to read.
Adam Nelsons Throw Clean site was great but recently I cannot open it, so it may have gone. Throwers.org may also be gone, and the forum "the ring" should be read but the training ideas are based on question and answer, and I don't get many questions answered.
Suggest you search the net for "shot put training" you would be amazed at the articles that come up. Also if you are serious the Nationa Throwing Coaches Association has a stack of videos, Rob Larossa is great, Larry Judge excellent honestly search and read then grab some DVDs.
Good luck and throw far...
