When performing swing exercises with the feet and knees together one could still obtain considerable distances despite a minimal body pivot. How come?
Even with feet together, you have a shoulder turn and to a lesser degree a hip turn. The shoulders are in BOTH the pivot components and the power package components. The shoulders transmit the pivot motion in the stroke to the power package. So even feet together can never be a pure non-pivot motion. Feet together drill does eliminate the Feet, Knee and Hip Actions but not the Hip or Shoulder TURNS. You still have the Accumulators 4, 2, and 3 or 1, 2, and 3 in that drill.
Imagine the precision the Right Shoulder needs to be the portal between Pivot and Power.
