Through the years I have worked, and continue to work, with a ton of talented pitchers. I absolutely love it! When I start working with pitchers, one of the first questions I ask them is “what would you like to accomplish with your pitching this year?” 99.9 % of the time pitchers mention how they would like to increase velocity, however; their method for improving velocity hasn’t worked for them and never will. Why? The common perception is that if they increase arm strength, they will increase velocity. This, of course, is the wrong idea and is sure to lead to arm injury in the future if they don’t learn how to throw with their legs and hips using proper mechanics.
As you can imagine, it is common to see incorrect movements that need to be corrected in order for them to throw faster. The majority of the mechanical flaws relate to: improper weight transfer toward home plate, not being explosive enough in combination with a wimpy stride, not utilizing legs and hips properly and using to much arm to throw.
