The research tried to introduce a whole new paradigm of swinging the golf club by enabling the utilization of the fuller and bigger body turn method, the beta swing, which have never been tried in the history of golf so far. The current golf swing methods, namely alpha swing, are mostly based on the single axis body turn method where the swing axis lies in the middle of the golfer’s body and thus the swing requires the golfer's head stay still during the back swing period. Technically the beta swing was defined as a golf swing where the golfer sees his golf ball in between the two arms during the back swing period. By seeing the golf ball in between the two arms, the golfer can free the head movement and thus take the position of making the biggest body turn possible.

Make bigger turns.
Initiate the movement by
the golfer’s head.
Separate the preparation
and the swing itself

 Cross Axis Swing Theory
If we use the cross axis as the center
of the body turn, the greater swing
power will be generated.
