This just in:

The DVD still sucks.

That's not to say people don't like Foley. His DVD is poorly scripted and produced.

Lastly, you can shift weight to the right foot without swaying or rotating, just by easing the pressure on the left foot (in some cases lifting the heel). Now, if that's how you shift weight to your right foot, you won't be in balance, and your body will start to move to your left.  But of course, this is exactly what happens in a golf swing.

Those aren't weight shifts. If your CG is in the same place, you haven't "shifted your weight." Pressures can change, but your WEIGHT is still roughly centered.

The only way to shift weight and keep your feet and head in the same spot (your feet because they're on the ground, your head because you want to keep it relatively still) is to move your hips well to the right. Nobody really does that.

Weight isn't pressure. I can move my weight LEFT and lift my LEFT heel off the ground: http://thesandtrap.com/t/48111/jack-nicklaus-on-a-centered-pivot/54#post_621950

The problem with that is that Snead did not have anything close to a "significant weight transfer to the back leg during the backswing.

I like the principal of what Sean teaches. However, one has to understand the two key differences between an arm dominant and body dominant golf swing. One has to have a body dominant golf swing in order to get real results from what Sean teaches. I like what he has done with Tiger swing.

"the weight of an object is the force on the object due to gravity"

There is nothing dynamic about weight. The effect (force applied) of gravity does not change whether you are still or moving. Lifting a foot off the ground does not change my weight distribution unless I also shift my centre of gravity at the same time. If I do not shift my centre of gravity then there is no weight shift to the right, no matter how much I "coil" or "load" or these other terms that are bandied around.

Your definition of weight is correct. However, the force of gravity can only act at the point(s) you contact the earth. Your mass and/or your center of gravity may not change, but the forces acting on your feet will definitely change if you were to distribute your weight differently.  That's where the confusion comes in.

If you lift one foot off the ground, the weight (force equals mass times acceleration, which in this case is gravity) measured on that foot will be 0.  The force measured on the other foot will be your total weight.  Your weight distribution will be 100% on one foot and 0% on the other, although your center of gravity will remain very close to your midpoint.

Really?  Keep in mind that I'm not actually advocating the old style swing.  I'm just saying that to me at least, it looks like he's loading significant weight onto his back leg through rotation and lifting and bending the back leg backwards without shifting his center line back very much.

Whatever, I'm arguing a point in an argument where the conclusion, that only the old style swing is a pretty, athletic one, is one I don't agree with!

I agree. And it's important to note that if your mass (your CG) doesn't change, the weight doesn't "shift" or "transfer."

If you move the CG to be over the other foot not lifted off the ground, then your weight has shifted because your CG has shifted. Absolutely.

If you lift your foot off the ground using your muscles but don't really shift your CG, you're going to fall over unless you put the foot back on the ground pretty quickly. This is not a weight shift.

In fact, imagine that you are standing on two scales simultaneously, with your weight evenly distributed. Both scales read 100 pounds. Then, in an instant, you lift your left foot completely off the ground (before putting it back down) without laterally moving your CG . What will the scale under your right foot say at the moment your left foot is highest off the ground?

100 pounds.

That is incorrect.

If you're talking about your measured mass, then yes, the only scale measuring anything will be 100%, but that "100%" will still only be 50% of your measured mass.

The above discussion ignores the fact that weight isn't pressure.

For example, standing on two feet slightly wider than shoulder width apart in a crouch, I can spike the "pressure" reading under my right foot if I push off hard against it (rapidly straighten my right leg). My "weight" will move LEFT in this case but, for an instant in a dynamic system (using our muscles), the PRESSURE measured under our right foot could spike to more than our body's actual weight.

Pressure ain't weight. If the CG doesn't move, your "weight" hasn't moved.

Our bodies have muscles that can exert pressure or relieve pressure dynamically.

I don't agree that only the old style swing is pretty or athletic either. I think there are pretty and athletic elements to virtually everyone's golf swing.

If you lift one foot off the ground, without shifting your centre of gravity, the force (or pressure) being applied by that foot on the ground will be 0, but there has been no change in weight. You still weigh the same amount, each part of your body still weighs the same amount and there has been no weight shift whatsoever. The weight distribution is still exactly as it was before, but the amount of force you're applying to the ground via your feet has changed due to the dynamic action of lifting one of them off the ground.

Yep. But listen to Dave and stop farting around with your right elbow and whatnot. :)

Clearly.  Some else posted something to that effect earlier and I was simply pointing out that if you think the shifting of a large majority of foot pressure to the back foot (even if there was only, say, a 5-10% weight shift backwards in a swing like Snead's) is a necessary element to achieve a pretty or athletic swing, then it's at east not logically inconsistent to dislike the more modern swing.

The weight versus pressure shift is an interesting distinction.  In most more modern, centered, swings, especially S&T;, teachers explicitly instruct to keep the weight split something between 50/50 and 60/40 towards the front foot, throughout the back swing.  How about pressure?  Snead may not have shifted his weight, but as part of a dynamic action he definitely shifted a large portion of the pressure to the back foot through his back swing (you can see that just from the fact that only his front toe is touching the ground at the top, and given he's not a ballerina I'd say that means most of the pressure is on the back foot at that point).  Would an instructor of a more modern swing also advocate not shifting much pressure to the back foot, gaining power with the uncoil supported by foot pressure relatively evenly distributed between the two feet?

One could argue fairly easily that Snead didn't so much "shift" pressure by lifting his heel or front foot as much as he did "relieve" pressure in his front foot by dynamically lifting his foot. Subtle - but important - distinction.

Our findings in 5SK - which we've been researching for years and will continue to research - indicates that with Key #1: Steady Head in place and a reasonable head position (not too far forward or too far back), weight distribution will remain virtually the same as at setup until late in transition to the downswing (when the hips will begin to push forward). The right knee and hip decreases flex, the left knee and hip increases flex, and the pressure (as a percentage of the whole amount of pressure in the body) under the right foot goes up beyond the 50/50 weight distribution. Numbers outside of the range we've measured in Tour pros (in either direction) typically indicate a poorer golfer (some poor golfers can get numbers in the range but tend to do so differently - perhaps by actually shifting their weight back to increase pressure rather than by decreasing flex and pushing off).

The peak pressure in the right foot is actually late in transition as the hips begin to push forward. Say around A4.25.
