You two are great!

Great instruction and video!

Interesting. But is there an exercise to improve my potential? Maybe long jumps in the bunker?

Nice! Nails the pedal perfectly.

Don't just look and think on the object (swing plan & arms movement), otherwise we will get the conclusion that the sun/moon/star are circulating around the earth!

Good stuff. Thank you!

.. could this be done with irons to a lesser degree to gain distance with the irons or would it ruin the accuracy and low point

Aha, now I know how to jump for speed, couldn’t quite work it out, thanks a million for the video 👏

Hi, can this test be performed on the 1D plates?

It wasnt a long drive swing? 😂

I'm very curious about a caveat here. I have a theory that my clubs are too long which is making me delay the vertical force. And your experience have you ever seen that be an issue? So for example my clubs feel too long so I can't just fully extended impact cuz I feel like I never going to catch the club up yet when I choke down dramatically like three or four inches I can time it perfectly but the only issue is I don't have any speed. But the contact is amazing in the ball flight is amazing it's just much shorter. Is it possible that equipment would completely throw off your timing is my question?

Hey Tyler. How does a biomechanist decide on kinetics vs kinematics? I worked for Dr Ralph Mann for years and we focused on kinematics exclusively. Kinetics helps from a teaching perspective in a way that totally changes how we can teach a student. Two sides of one coin I think. With a student with a wipey action we probably would take a different approach if thinking in terms of kinematics only. Great stuff.

Long Drivers College … Ground force 101! With Professor Zuback !

James that was a great presentation. Thank you for all your inquisitiveness over the years.

Can someone send this to JT?

At what point is the trail foot applying pressure towards 10:30? And is there re-centering

Data driven analysis might appear to be impressive but without a true understanding of the information it does nothing for the average golfer. Everyone watching is most likely impressed but have learned nothing that will improve their swing. Basically, people like this are making a living out of confusing the $#!t out of people. Have any of you viewers learned anything that you're excited to grab a club and go outside and try right now?

Thanks Greg & Jason, I love this stuff that was the quickest 8 min video ever! I was a biomechanist and at 60 I have goals for golf. I always thought a force couple was best but I didn't know how to do it, plus I was totally ignoring the Moment arm effect to create rotation with a lateral force OH MY I have some practicing to do!! Thanks again, brilliant!

Really good information Reminds me what I need to work on for my body type and not to spend time on things that are not for me 😊

Why are there players who even having a great looking swing their strike is really bad

Great Work Greg & Jason really impressed, I was a university biomechanist and still a mad keen smasher of the golf ball and this is gold!

It is so interesting!!! Thank you guys!!

Thanks for the great video, makes a lot of sense that the lead foot AP would be quite higher than the trail foot

That's the first time in nearly 40 years of golf that I try a drill that makes me obtain a significant result instantly. I am not a long distance golfer, just an old guy looking for ways of getting solid contact at hitting the golf ball anytime. Jason here brings the keys to improve at light speed! Thanks a lot, mate 😁😉.

Never thought about moving my lead leg backward in the downswing but in retrospect I see this move all the time in the pros.. vey insightful. Thank you guys!

Can U pls let me know where u can get those pressure pads? Thks

Just swing the damn club !

Wow!!! Very Impressive Learning generated here. Thank you.

I want to suggest that you do the feet-force graphic from the front of the player just like the video. I would make it easier to look at the video and see the ground forces

Thank you! This content is gold.

These videos with Jason are the best on the golf internet. WOW

These are great, how many reps of each should we be doing?

This is mind blowing.

Scotty Scheffler uses this clearly when driver in hand as well as fairway woods and longer irons

Great video showing how you can do a lot of work to improve the vertical force.

Yea good stuff here…seems like great exercises for any golfers.

Is there anywhere in Scotland that has these facility’s ?

Very nice guys !!

Thank you guys again and again!!! Amazing the work that you guys do!!

Wow I'm really loving the explanation for the "anti-jump" pattern. It helps me to think of it more like a superhero taking off to fly. I'm dying to get to a trackman to see some numbers

Thank you so much guys!!!

I'm having a hard time taking anything away from the visual force lines. There's just so much going on. You say a few times to apply force with both feet at the same time but to me it looks like you very clearly switch from trail foot to lead foot (red line getting shorter as blue gets longer). I would expect based on your description that both lines increase in size at the same time.

Please please do one for frontal plane torque 🙏

It looks hard to understand the drill and how to do it.

Jz is the real king of grf and rotation. Not easy for us shorter guys we need to use this as much as possible

but how does the force from the lead leg inclines towards the target though?

Thank you so much for these informative videos. Saving up for get them plates! Can't wait for the lvl 2 Seminar!

Very interesting!!! Thank you very much !!!

I really like what you do!!! Thank you very much!!!

Great drill. Is there a progression II where you jump backwards off the left foot as the club is coming through?
