Clubhead Speed

[ellamia]

Here is a crazy one...  in order to create clubhead speed, you need torque.  Where does this torque come from?  I believe it is the force against the ground with your lead leg.  This is reaction torque.  The quicker you can transition to your left side (right handed golfers) then you are set to release the club with the hands.  I don't think the best way is a longer, wider, more turn blah blah blah.  You need torque to create angular acceleration!   That's the only place you're gonna get it.  From the ground.

Let me know what you guys think about where the power comes from.

Turn matters. 

For those who just do not turn, like 20 degrees of hip turn, and 60 degrees of shoulder turn, they could do more. It is hard to generate the required rotational speed while taking such shorter turns. You would have to be so arm dependent. If you take away the club from an amateur, have them turn their hips 40 degrees, and their shoulders 80 degrees, I think mostly all golfers can do this.

It isn't that simple. There are multiple levers in the golf swing that can cause acceleration.

Using the lead leg properly, and having good timing with all the stuff before doing that, ramps up the turn rates more. You can absolutely keep your left knee soft, and have your hips stall out, and have high clubhead speed. I raise my hand to this. 

Sliding properly and then extending the lead knee properly helps with hip rotation.

I wouldn't put it that way. Transitioning correctly, and with proper timing has a lot of benefits. It controls the backswing length. It sets you up to allow you to push off your left foot to keep those turn rates up.

As for what a golfer should feel, it might be completely different. 

Golfer A: Very short swing, little turn in the backswing. They might need to feel MUCH more turn in the backswing and feel a weight shift much later. 

Golfer B: Very long backswing through tons of turn. They might need to feel the weight shift happening sooner to control the backswing. 

For some, they might not want to transition to the lead side sooner. It could be costing them. They are losing potential power by not optimizing their backswing turn. There is a reason why partial wedge shots go shorter than full swing shots. It is much less turn. A quicker transition could cause a loss in power.

How do you mean? Like twist against the ground to create torque? It is not that absolute if that's what you are suggesting. There is a lot of good info out there to debunk and clarify lot of this stuff. Dr. Kwon's research and publication (you can Youtube) is great and somewhat simplified if you are interested.

It’s a bit of an oversimplification but I generally disagree, mostly on the fact that it’s possible to shift forward incorrectly and not actually use the ground well. Time is a factor - as in time to both generate and transfer the energy from the body to the club head - and some of that is related to having more turn and wider levers. There’s a reason you don’t swing 120 mph if you start from A2.

A lot of the force from the body is rotational though, which is aided by how we use the ground. It’s just kind of how our body works. It’s how you swing a club fast, a baseball bat, throw an uppercut, hit a tennis serve, etc.

That doesn't sound right. You can create torque by rotating your body while sitting in an office spinning chair. Your lower body will of course spin in the opposite direction, but I don't think you need the ground to generate rotational force.
