Using the overload to underload approach to train the pitchers body and central nervous system to increase arm speed is the right concept but the wrong approach when using weighted balls. The problem with using weighted balls is that it sacrifices the arm to teach the body how to move weight more quickly. To understand how backwards this weighted ball approach is we must first look at what role the arm plays in the pitching delivery.

The Role of the Arm in the Pitching Delivery

The role of the arm is to get into position to allow for the transfer of energy from the lower kinetic chain into the upper kinetic chain. Once this energy has coiled the shoulder during external rotation the arm’s role is to deliver the pitch to its desired location. Never does the arm work to generate velocity except for using the elastic properties of the arm muscles when coiling during the energy transfer. To better understand the sequence of events through the entire kinetic chain, which leads to the top velocity of the pitcher, you need to learn the revolutionary approach to pitching velocity called 3X Pitching. 3X Pitching proves that to increase the coil of the shoulder during external rotation the pitcher must first increase linear stride power and then transfer that power into core torque at front foot strike.

Why Weightballs are a Waste of Time for Pitchers?

Based on the understanding of how velocity is generated through the entire kinetic chain of the body stated above and also in the 3X Pitching approach, you can see that training with weighted balls using an overload to underload approach is a waste of time because it does not work with power pitching mechanics. Yes, this weighted balls approach may increase arm strength, using the weights, and may increase some arm speed, through training the central nervous system to rotate the arm faster, but the final result will be much less effective than taking a total body approach to velocity like with the 3X Pitching Velocity program.

I used the Overload Underload weighted balls throwing program for years when Dick Mill’s once preached it back in the 90′s. He now credits it to causing injury. It happened that I was using this program the year I torn my rotator cuff. I am not saying that this program was the reason for my tear but it did speed up the process of the injury. My problem was I had bad mechanics. I was an all arm pitcher and when I used this program it made everything even worse. The overloading with the weighted balls put more wear and tear on my cuff and in the end, even if I had added a few mph, it wouldn’t have been worth the extra wear and tear that came with it.

If you are looking to use weighted balls to increase velocity, I really believe that you are looking for the easy answer here. Increasing velocity is developing power pitching mechanics and also developing yourself into a power pitcher. The 3X Pitching Velocity program gives you all of this with a revolutionary approach to pitching velocity. This approach uses the famous 3X Velocity System throwing program to develop the 3X mechanics and the famous Fusion system which is the strength and conditioning program to develop you into an elite power pitcher.So, stop looking for the easy way out and get serious with a serious velocity program like 3X!
