How to maximize pitching practice and bullpen sessions

Joe Janish from the blog "On Baseball" has posted some good tips on getting the most out of pitching practice -- from throwing bullpens to improving skill on the field. He draws upon his many years of experience as a baseball coach. The article's main points were as follows:

1. How a pitcher approaches his bullpens often directly correlates to his performance on the mound in games, regardless of the individual's skill level.
2. Whenever a pitcher takes the mound -- be it in a practice session, in the bullpen, warming up between innings, or in a game -- he must have a SPECIFIC plan and he must focus on executing or following through with that plan.
3. A pitcher who plans his practice ahead of time and focuses on its execution will be much better prepared come game time -- and will enjoy regular improvement in his pitching performance.
