It boggles my mind that Jason Zuback, in the early 2000’s, was around 200 mph in ball speed (Ryan Winther now holds the official record in ball speed at around 227 mph and an unofficial mark of 237 mph).
*Edit – as of today, the current world record holder in ball speed is Sebastian Twaddell, Golf Ball Speed Record Holder 2025 – 246.8 mph (Trackman).
That’s because I have actually gotten into the mid-190’s in my 40’s without having to live in the gym because of technique over muscle power, but one thing I can tell you – the clip below puts the Modern Golf Swing industry to shame.
All you have to do is watch from about the 6:40 mark of the video, and you’ll see what I’m talking about:
Jason Zuback Goes For 200 MPH Ball Speed
Here are selected quotes on how Jason Zuback achieved the 200 mph mark in the lab, and the times where you can find them:
7:03 – It’s all due to a chain of events called “kinetic linking.” The energy starts in Jason’s feet. Jason plants himself on the ground, and winds his body up like a spring.
Now, that sounds a lot like the Modern Golf Swing stuff, doesn’t it?
Except for the fact that Zuback’s is a Classic Golf Swing model, and I would bet you that you won’t hear any Modern swing reference to using “the ground” or “planting” before 2007, because we’ve only begun to hear the “using the ground” stuff since PGA Tour players began jumping into the air at impact due to their bad technique.
So, the Classic Golf Swing guys were “planting” themselves “on the ground” and “winding up like a spring,” you’ll hear, as far back as 2007… which means all of this Modern Swing mumbo-jumbo about springs and using the ground isn’t even original… now, look at the “lifting heel” of Zuback’s computer model as the analysis continues:
7:23 – The power multiples as it travel upward through his knees, and with the smooth twist of his hips, the energy races into the massive muscles of his core.
So, what’s missing in the Modern Golf Swing?
Oh yes, the part I underlined in the previous quote – the smooth twist (or turning) of the hips!
Modern Golf is missing everything from the hips on down, so no, they are NOT using the ground or their legs and feet as the analysts on TV try to tell you.
It’s pretty simple – if you’re not letting the hips move freely, how are you then using your legs and feet and the ground?
All you’re using is the core region, and that’s why all the backs are breaking!
