The spine triangle is formed at address. Once the player takes his stance ("I"Triangle), grips the club and addresses the ball ("Y" Triangle), the spine triangle becomes the axis of rotation in the golf swing.
There should be a minimum curvature of the spine at the shoulders. There should be the feeling of “bowing” the spine, thereby placing the shoulders adjacent to the chest, with the feeling of your breasts pronating toward the golf ball.
Although there is force and movement for the other four Triangles.
There is no force or movement for the Spine Triangle. It is the point of pivot for the swing rotation.
The "TRICK" to the golf swing, in all playing conditions, is to move the 4 triangles properly (”I”, “Y”, Forward & Reverse Lateral), while keeping the Spine Triangle as STATIONARY as possible.
Some golfers will find this easy and will be able to hit a ball relatively quickly, while most will need to work at it.
We believe that the Five Triangle method will solidify the horizontal movement of the golf swing and stabilize vertical movement of the Spine Triangle.
This will expedite the learning curve to hitting a playable golf ball.
