Here's another baseball pitching tip...
One of the most important factors in maintaining or building functional strength and/or pitching velocity is the recovery process that takes place following a workout, practice or game.
By eating properly and getting 8-10 hours of sleep (naps are OK, too), a pitcher can hasten the healing, health and recovery process of the body, which better prepares them for their next performance.
Don't forget the recovery part!
Work on it!
