Left leg and hip through impact

[Iowa Hawkeye]

How do you guys use your left leg though impact?

Keep it flexed and use it to pivot your hips?

Do the "Power Pop" where you snap it straight and throw the hip through?

Let it naturally rise under your hip?

Other?

It's straightening but not yet straight. I don't really have to think about my left leg at all. Whatever I do with it I do with it as a natural result of the rest of the swing to that point.

For a short time I thought of driving my left knee down and forward as a way of getting my hips pushing forward (to target), but that thought didn't work very well.

Agree, you do not want to go lock straight with the left leg. One of the top US collegiate players last year previously had a little problem with this. He got a training aid that forced his left leg to stop just before going completely straight, and he fixed his problem and became a really great ball striker. If you snap it straight at impact, you could well be in for a knee problem in time -- I don't know that because I am not a medical doctor or exercize science type person, but any time the amount of torguing force generated in a golf swing is driven into a locked left leg, there has to eventually be a problem.

Now after impact and when you are fully released and relaxed, maybe so, but almost straight is really all you need. Great drivers don't finish leaning forward over straight left legs, they are still behind the lead foot, but have almost all the weight moved to the left leg... and just a light toe of weight on the right foot -- you could tap it up and down. A little flex at this point is a lot better for the knee joint. It may look straight, but it is not locked or fully extended. After a full out smash, you should be able to do do a little up and down motion on the left leg and still be perfectly in balance. As you come into impact, there should be a slight feeling of flexing down or driving the body into a tiny squat, then you strike the ball and let the turning body and arms cause the rise into the finish.

As a side note, if AK did one of his "come out the shoes, flying right leg" smashes on a straight, stiff and locked left leg, he would need surgery.

I would say let it rise athletically and naturally, but not snapped into a locked position.

Yeah, I keep my knee flexed. I was just curious to how everyone else does. I tried the old Tiger style leg snap for one swing and instantly knew why he destroyed his knee.

I straighten it and actually focus on it during the swing. One of the things i fight is a negative hip angle which kills accuracy.
