I would recommend understanding how the body works when it performs the tasks of throwing and hitting a baseball. If you're eager to learn go to ****** and Paul *****'s stuff. He won't return emails or calls. However try to soak up as much of his info as possible. Steve Englishbey broke off and did the hitting side of ***** while Ron Wolforth broke off and did the pitching side. Wolforth's is easier to understand than Englishbey's. Englishbey's is full of a lot of scientific terminology. However once you get it, it will be amazing. Trust me I've spent thousands of dollars on videos and most of it to find out that these 2 programs were the best.
