You want to add a few MPH to your fastball without doing anything special?
Stretch. Yep, get your flexibility equal in each leg and hips. This simple trick will allow you to be balanced and more fluid when your hips rotate creating better torque and keeping you online.
Lie on your back. Place one leg flat on the ground and have a partner stretch your throwing side leg back. Keep your leg straight and notice how far that leg can stretch backwards. Now switch legs. I guarantee they will be different.
Get these equal and you’ll see a performance enhancement in most of your playing. And you’ll add MPH to your pitching without even trying.
