i just started having my 7u son do these....adjusted the weight of the ball down to match his age...2lbs ball...since the goal is to do these explosive and fast.
Both sides since you want to even the strength on your body to decrease disproportionate muscles which can possibly cause injury… keep it even and stable!
My 12 yr old Softball daughter has gained tremendous power in a fairly short time by following these, but just today I noticed Sierra is working with a 6 Lb and my poor daughter has been working with a 12 lb this whole time. Oh well lol
To add some real numbers to what her gains have been, her bat speed before working with the med ball daily averaged around 52 MPH, with an exit velo of 68. The after numbers are bat speed 60 MPH with an exit velo of 78.
