I've received so many PM's and Emails about I/R I've decided to speak more about training Internal Rotation, and the progression we use to build a foundation for the underhand throw.
First of all, we all know that grip, stance, posture, wind-up/load and leg drive all contribute to pitching a softball. IMO, none of these are on my list of "absolutes". They are "styles". That is, not every high level pitcher uses exactly the same style any of the above listed requisites of pitching.
The ONLY thing I view as an absolute in pitching is Internal Rotation. Which is why I focus on it so much. If I can teach a young lady/man to "throw" a softball correctly and efficiently, and literally "play catch throwing underhand" as naturally as they would overhand, my job becomes so much easier when it comes to adding "style".
With that in mind, lets talk about I/R as a training method to that end. Using drills that isolate the motions of I/R, and are progressive in nature to involve more and more of the sequence.
First of all, I/R is a "motor skill". Whether natural or learned, it is a skill that can either be taught or enhanced by focusing and training the bio-mechanics and physics that cause the motion to occur, in sequence.........
One of the first things that has to happen for a proper I/R delivery, is that the upper arm (bicep) must be trained that it is the stability point for Internal Rotation. It rotates AND stabilizes vertically. It must be properly positioned in close to the body and vertical in order for the forearm to internally rotate on the tightest radius possible. It ALSO must be trained to pass kinetic energy from the proximal to the distal parts of the sequence. IOW.........The energy must be passed from the arm circle, through the upper arm (proximal part), to the forearm (distal part) and down through the wrist into the fingers and ball.
In order for this transfer to occur, the upper arm must be caused to decelerate to almost a stop when it reaches the stable vertical position close to the side, and then continue forward as a follow through energy dissipation result........That cause begins with Internal Rotation of the forearm "taking the energy" from the arm circle, causing decel of the upper arm........
Take note of these pitchers stable vertical position of the turning upper arm.....And how the elbow stops advancing through the circle for a split second........
In order to train the upper arm to stabilize, and transfer energy, we need to limit it's ability to do anything but turn away then face forward by responding to the commands of the forearm as it REMAINS in the stable vertical position close to the body.
The quickest way I've found to accomplish this is by using what I call the "lock it in" drill. A drill that keeps the elbow at the side, thereby keeping the upper arm stabilized and vertical and transferring energy to the forearm........
The student must throw the ball using External Rotation then Internal Rotation/Pronation of the forearm WITHOUT moving the upper arm (elbow) back/away, OR forward past the body until release causes follow through.........It can turn back but it cannot MOVE back.........
More in the morning as we progress to "Unlock It"..........
