I have (much) more to say about hitting and pitching than I talk about in my Rotational Hitting 101 DVD and Pitching Mechanics 101 DVD.
Some instructors try to solve this problem by embedding their supplementary information in posts and threads in client-only message boards. I find this doesn't work well for most people -- for people who aren't completely obsessed -- because it makes finding critical information a difficult and time-consuming process.
As a result, I have created this web site to help people understand my ideas.
By registering, non-clients can get free access to a number of articles, including my core hitting presentation The Truth About The Swing. However, the only way to get access to the client-only portions of this web site is to purchase one of my pitching or hitting webbooks or DVDs.
I also frequently post to Twitter as @ThePainGuy and post information about updates to this site and large amounts of free information.
Give me a follow if you are interested in learning more!
