How To Generate Force - The Answer Is In Your Back Knee
In this video, we talk about what your back knee does in the pitching delivery. When we start our delivery moving forward we want to make sure that the back knee stays straight and might even bow outward a little bit towards second base. We want to make sure that our knee is not bent inward as this will allow us to lose some kinetic energy in our delivery and take away some velocity.
We want to make sure that our knee stays linear (straight) until our landing foot hits the ground. If we can accomplish this, then we will not lose the kinetic energy we have created during our delivery. Check out the video and you will see exactly how this should look.
