Good one...I think that is Bubba Watson, who plays left handed, so for a right hander swinging like this he would be a right leg pivotal axis player, at least for the driver. I have noticed that some of the long drive guys appear to do this. They tee the ball very high, and stay back on the right leg.

More discussion...

Hitting Up On the Driver . . . Correctly

In this sequence, note that Bubba tees the Ball ahead of Low Point. The result is an Upward Swing Path, less spin and, accordingly, more distance (but also less control due to the 'knuckle ball' effect). The high tee is required because he would 'Top' -- or even swing over -- the Ball if it were pegged lower.

Bubbalicious!
Would Bubba also have to tee it up a bit to the inside as well?

I was just joking around with that Bubba Picture. It was the Farthest one I could find from one who Drives with the Right Leg. But, it's still pretty amazing how far he can hit the ball with that pivot. I don't know if that affects the "mechanical advantage" comparison.

I have heard of techniques where the Pivotal Axis is on the right leg. Are any of you familiar with any of these?
Pivotal Axis???

There is no pivotal axis!
Whenever the hips are moving, the legs are moving, the knee flex is changing dynamically, as is the ankle joint - because of the changing 'axis tilt' of the spine as the hips slide and the 'cylindrical' motion of the hips relative to itself under a stationary head (think of a disc (hips) moving around the outside of a big sphere(center of sphere - head)) moving the hip sockets in a circle.

It is not a pivotal axis unless you take it very literally - the terminology is misleading though - it could be in the sence that your ankle is a pivotal axis, or your wrist is a pivotal axis or your neck is a pivotal axis, or your elbow is a pivotal axis....

You could say that the legs act as constraint to the amount of displacement that can occur when the hips make their motion, however that does not in any way qualify it as a pivotal axis to the pivot - certainly in the way you mean't anyhows.

You state that there is no pivotal axis. VJ Trolio writes about a downswing pivotal axis located in the region of the left leg in his book on Hogan, and he states that the pelvic rotation angular momentum is enhanced if the COG is nearer to the pivotal axis. Are you saying that his idea about a left leg pivotal axis is wrong-headed?

Secondly, during the downswing-followthrough-finish part of the swing, the pelvis rotates 135 degrees (presuming a 45 degree pelvic rotation in the backswing). I personally believe that the pelvis essentially has to pivot over the straightening (firming up) left leg, and that it is impossible to pivot over the right leg, which is becoming progressively more unweighted during this time period. Are you saying that I am wrong to think in this manner?

Here is a video link to Shawn Clement hitting off one-leg.



I believe that he is pivoting over that left leg during the downswing/followthrough. Do you disagree?

Jeff.

Who will speak for the Left Leggers?

What legs? There are only Feet, Knees, Hips, and a head.


BTW Daryl- Andy Plummer and Mike Bennett have been posted about in this forum. Have spoken with Yoda and even lurk among us.

Johnny Miller, Ben Hogan, Sam Snead, Jack Nicklaus and Vj Singh stay centered with more weight on their left leg.

Bennett and Plummer are okay guys.

Are you sure? I could swear that Homer talks about Legs hundreds and hundreds of times. Doesn't he say:

1. Drive the Legs.
2. Start your Downswing by swinging your left leg toward the target.
3. Drive with your right leg.
4. Shift your weight to your left leg on the backswing and onto the right leg of the downswing.
5. Don't move your legs in a non-pivot swing.
6. Move your legs in a pivot swing.
7. Don't take a cart, use your legs and walk.
8. Passive legs.
9. Active legs.


These are such familiar phrases. If Homer didn't say them, then who did? The legs are body components. Why aren't they swinging components?

I don't know Bennett and Plummer. Who are they?

This thread started going downhill after the first post. I was hoping it would get lost.
