HIPS & CLUB HEAD SPEED
The hips are:
• Located in approximately the center of the body.
• Designed to support and stabilize the legs and spine during movement.
• One bone with no ability to flex or bend.
The hips main function is to move the amount necessary to allow the legs and spine to support the shoulders and fast moving arms. The spine is the only mechanical connection between the hips and the shoulders. For the hips or any part of the lower body to transfer speed or momentum to the shoulders, the shoulders must rotate with the hips. There must be a rotating mechanical connection in order to transfer speed or momentum.
- IMAGE 1: This is the position where the major power is applied in all golf strokes. The right triceps and forearm muscles both extend and rotate the hands through impact. His hands are approximately waist high. The club head is above his shoulders and the club head speed is less than 40 mph.
- IMAGES 2 & 3: The red line of the polo has moved only a few inches and rotated less than 3 degrees. The club head will increase from 40 to approximately 130 mph during this time. There is virtually nothing moving but the arms.
The simple observation of the pictures of Tiger shows that the only thing moving with any speed is the extension of the right hand (uncocking) and the rotation of the forearms. Forearms strength (extension and rotation) is what produces maximum club head speed.
The spine is the only mechanical connection between the lower body and upper body below the shoulders.
If the button is not moving with high speed along with the hips and any other rotary motion of the body, there can be no transfer of any speed, momentum, or power from the lower to the upper.
BODY ROTATION IS NOT THE MAIN SOURCE OF POWER IN THE GOLF STROKE!
The arms are able to generate the power necessary to create a 150 mph club head speed.
