>>> I did figure that out.I am wondering in the data you mentioned below comparing one armed and 2 armed swings how one armed back arm compares with one armed lead arm.CAn you break it out a little more for us ? <<<

Hi Tom

I never took bat speed reading while working with the lead-arm. Most students have the tendency to use the un-flexing of their elbow to accelerate the bat. This resulted in disconnection. My work with the lead-arm was to teach them to keep the arm across their chest and allow rotation to bring the hand (and bat) to the contact zone.

I was not that interested in the bat speed they developed. I was more concerned that they learned the proper role of the lead-arm with rotational transfer mechanics. The proper use of the lead-arm also became very important in correctly performing the “seven iron” (THT) drill. – Most students have the tendency to separate the lead-arm away from the chest while first learning the drill, this leads to many problems.
