While acceleratory muscles are important for initiating a throw, muscles involved in deceleration are equally as important.
It is critical to work on the antagonistic muscles because they are the brakes to your motion and will help direct and tune your speed.
Among the most important decelerators is the rotator cuff, which consists of 4 different muscles that make the throwing motion possible.
To help strengthen these muscles, it is advisable to perform rotator cuff exercises almost every day, or at least several times a week.
These can be done with no weights, or light weights like light dumbbells or soup cans.
When it comes to pitching, longevity and injury prevention should be at the top of your priorities. Pitching can be hard on the body, esspecially when deploying different types of pitches in your game.
