Weighted Ball
                     Weighted Ball
The throwing motion is all about the 
creation of leverage and the shedding 
of leverage. The physics are simple — 
the more weight you put in your hand 
the more leverage you create. We often 
see kids in a pitching clinic going 
through the throwing motion with a 
towel in their hand.
We understand what they ‘think” they 
are accomplishing but realize what they 
are “actually doing”. (ie, leveraging up 
the acceleration phase with resistance 
— the towel — while increasing the 
weight -the towel-
the weakest joint has to endure in 
slowing the added weight- the towel- 
down. Normally this weight in the 
decel phase would have been shedded 
with the release of the ball.)

The Overhead Throwing Motion & the 
Weighted Ball.
So what about weighted balls? Weighted ball throwing programs? We have all read 
countless articles on how safe they are and how evil they are. As you might guess this is 
one of the hottest topics out here at this moment in baseball and football. Tomorrow it 
will be something else, but today it is “do we or do we not throw weighted balls” as part 
of our training program.
For us it’s simple. When in doubt don’t.
In the countless meetings we have had with orthopedic surgeons and “medical 
institutions” in the business of sports medicine, along with the many meetings with top 
university sports research groups, we hear over and over again about “leverage and 
physics”. The common area of concern is always “repetitive inline (linear) forces and the 
need to create counter forces (cross training) to fend off “grooving” injuries. Funny, we 
have never read anything out there about “grooving” but we keep hearing the word in 
describing how certain injuries in the shoulder occur. Read more Visit;
