Weighted Ball Throwing: An Advanced Training Tool

Another year, another chance to get better. At Infiniti Sports Performance, we highly encourage most of our baseball athletes to put a baseball down once October hits.

However, the baseball culture still pushes playing fall ball, which is highly unfortunate. My question is, for what reason?

At the end of every summer season, your arm has a bunch of mileage on it with not a lot of maintenance performed on it. You LOSE mobility in your throwing arm AND you usually see a dip in velocity.

So, if you didn't throw a lot during the summer season, then keep throwing so you can add onto the chronic workload of your arm. If you DID throw a lot, and you're part of that example that already lost mobility, velocity, and strength in your arm, do you really think you should be showcasing yourself?

With that being said, hopefully you at least took a few weeks off from throwing. When the body is broken down from a long season, don't mope and feel sorry for yourself. Rather, look at this stage as a new opportunity to grow and build on what you presented this past season.

This brings me into the weighted baseball discussion. We see time and time again kids wanting that acute spike in throwing velocity so that they can showcase themselves in front of college coaches. That acute spike in throwing velocity usually comes from unsupervised weighted baseball throwing.

We developed the VELOBOOST program from current research and our knowledge base on the topic. What we DO know, is that strength is the foundation for all athletic qualities. If you are not strong, you will be left behind.

Yes, some of us can throw weighted baseballs and see tremendous benefits from it.

Our very popular VELOBOOST program is starting up shortly, so I thought now would be a good time to go over the W's for weighted ball throwing:

- WHO should and should NOT be using them

- WHAT they can be used for

- WHERE you should be feeling engagement when we use these tools

- WHEN we should and should NOT be using them

- WHY we should use them (in certain cases)

For every thrower, it's important to get strong simultaneously with a throwing program. The foundational strength from which you build in the offseason is built in a systematic way so you're able to display the athletic qualities from which you're pouring your heart into.

Let's go over the W's of weighted ball throwing.


This is the most important "W" for this post. In our VELOBOOST program, we limit the minimum age to 14 for a few reasons.

1. This is usually the age where kids are fully acclimated to playing on 90' bases and throwing from 60'6" on the bump

2. Most 12-13 year olds aren't STRONG enough to throw a bullet across the diamond

3. Throwing mechanics are not fully matured just yet

Now, let's say you're "of age", have a good relative strength base, and display efficient throwing mechanics WITHOUT any pain, then this advanced training tool may be able to help you.

If you are unable to throw a 5 oz. baseball without pain, this advanced training tool is NOT going to help you. Rather, it will steer you in the wrong direction.

In last year's program, the average 5-RM deadlift was 255 pounds and the average velocity BEFORE any training intervention was 84 mph. These kids were already pretty strong and could throw decently well.

Again, unfortunately, the baseball culture looks for velocity first and foremost for pitchers. Yes, weighted baseball do work. They will make you throw harder. However, doing so without any supervision and direction, you will end up hurting yourself. This is where Infiniti Sports Performance comes in. We are the professionals!


Throwing weighted baseballs have shown to increase throwing velocity and, in some cases, arm speed. For more details on the research of weighted baseballs, click here.
