Sklz Weighted Baseballs 10oz. and 12oz.

That is completely too heavy. A overload/underload throwing program should consist of a 4oz. ball, 5oz, and 6oz. It may not seem like a lot of weight but that is a 20% change. It allows the player to keep his mechanics but also work on strength and speed.

Johnny is right on. I dont know what they do with the 10 & 12 oz. balls but that should not be used for throwing purposes. With some of the kids I work with, we use the heavy weighted balls (over 6 oz.) for shoulder strengthening. I have the player sit on a stability ball a few feet from a pitch back and work on getting the hand and arm back and coming forward through the ball. But like I said this is done from maybe five feet away in a controlled way.

What about Ron Wolforth's program?

Wolforths programs use ap to 1 and 2 # balls but it just part of the throwing prgram not just pick them up and throw them.
