What do you believe the function of the lead arm is in the swing?
Five, correct the flow of bat and body creates the change in barrel direction behind you. Learn to create the change in barrel direction leveraging all available resources. TJ calls it the gyro effect. Done correctly the scaps will become retracted and one will have a tough time hanging on to the bat.
You are going to have to relate this to a baseball/softball swing for me if you want me to follow along. What I am getting is he wants you to pull hard with the lead arm....
