Hi, Robin here. Let’s talk a little bit about
ground force reaction. Now this is a biomechanical subject. Something that’s been researched
a lot recently. But biomechanics are great, but they’ve got to be appliable. So the way
I’m going to talk about this today is not into the micro-detail. I don’t think players
learn with fine details. They learn from just having the general concept. Things which they
can relate to and apply and do during a swing. And that’s the way that I’m going to try and
explain it today. All right, when you ask players in a golf
swing what creates speed and distance. The common answers would be shoulder turn, pressure
transfer, weight transfer. Maybe wrist cocking, and logging, arch, etc. All good stuff, all
has some effect in distance. But very few will say the ground force reaction, the force
from the ground. I call it just vertical force. Because if I think about a player. I’ve said
this before, basketball throwing a ball. If they just threw with their arms and nothing
from the ground, it’s very difficult to create distance. They’re going to have to use a lot
of upper body strength to create any momentum and create any distance in the ball. But if
they use the ground a little bit, they time that little jump with the release of the ball.
Actually they can put a lot less effort in to get the same distance, or even more distance.
Think about almost any hitting sport. Baseball, you’re always gonna see that little bit of
a thrust upwards. A push from the ground timing with hitting the ball. It’s essential to create
speed in an efficient way. Golf swing’s no different. If you’re using the ground efficiently,
you’re not having to overwork your upper body muscles, your arms, your wrist to create distance.
That gives your more efficiency which it turns out to be more consistent. Now if you’ve got this element already in
your swing then there’s maybe not much room for improvement. But if you don’t have this
element, there’s a huge room for improvement. Recently I had a student who, and this maybe
a good way for you to know if you’ve got this element in your swing. They look [inaudible
00:02:22] buckled at impact, telling me they really had no vertical force. Just adding
a little bit into their swing, they picked up 10 miles in their club head speed. Now
I know that doesn’t sound realistic. Yeah, maybe that’s a one off. But it kind of gives
you an idea. If you don’t have any of this going on and you add little bit, there’s a
huge room for improvement. So one, how can you feel this in your swing?
The most successful way I’ve had of teaching players to feel it coming down is the left
foot only drill. Putting their right foot behind them just for a little bit of support
and balance. And basically what I want you to do is as you’re coming down, I want you
to feel like you’re jumping up from your left foot. There might be a odd player out there
who will actually jump up, but most of you won’t. Most of you the pressure under your
left foot will just get lighter, and that’s what we’re looking for. So it’s your normal
swing from left foot only, right foot behind you. Feel a jump up through the ball. Some players will ask, “Well do I not need
to push down first, then up?” But it’s correct, that happens. But do you need to think about.
No, I don’t think so. Because if you’re jumping up, you’ll have automatically pushed down.
So simply left foot only, put the ball in the tee. And try to feel that vertical force
through the impact zone. Now I’ve tested this on TrackMan. And I would
say at least 90% of the time, one player said maybe after 5 or 10 balls. Actually create
at least their equal club head speed with this left foot only drill as what they do
with two feet. So maybe that gives you an idea of just how important this is. I say,
at least equal club head speed. Very often they create more club head speed. So then basically once you got that feeling,
go back to your normal set up. And then basically you’re feeling the same feel from your left
side through the ball. That’s basically getting some ground force reaction in your swing.
If you time correctly, your club head speed will go up. But I think there’s a lot of other
benefits from using the ground correctly. As I say, you won’t have to overuse your muscles
in your upper body. That can affect many things, ball striking, swing plane, efficiency and
consistency. So first of all you got to workout if you need this in your swing. If you feel
like you do, give this drill a try. I’m sure you’re going to see some change in your club
head speed, and the distance you’re creating. So thanks for watching. And yeah, give it
a try.

  1. Excellent subject Robin. There is tons of discussion of hip rotation and lateral shift/weight shift but almost nothing on what you're calling ground force. Just recently I've started incorporating some lift into my swing and it's significantly increased my distance with no ill effects on my accuracy. Thanks for the video.

  2. Very accurate Robin. I have a mate who is 1.60 tall but has a pivot motion and a large backswing all sincroniced and shoots 260 yds with the driver. when I see your video I remember him. Well done!!!

  3. top notch, TOP NOTCH.  All my work on drive/holding has me squished down on the downswing. This width and proper turn avoids all sorts of release issues.  Great stuff.

  4. Robin, I tried this with driver – It seems ball lunch higher but distance is still there. Is this expected?

  5. Hi Robin, Great video. I started doing this recently because I noticed my knees were collapsing at impact. Now on video my impact position looks much better and left leg is posted. And my thought is to PUSH straight up with left leg (almost like a jumping feeling)
    My question for you is when do you think you should start pushing up with left leg. I was doing this as I started my transition, but I wonder if that's too early? I have been hitting shots thin when I miss. And I wonder if its because I'm pushing up too soon? Any thoughts?

  6. Very well put young man. It is indeed the hidden secret to the golf swing. It is so well hidden by the hip rotation that follows, that you cannot see it happening, Once I mastered this my entire golf world changed

  7. After more than 50 years playing golf I thought I'd seen every worthwhile swing tip that existed. I was wrong! This tip immediately added 5-10 MPH to my swing speed with a 6 iron. At first I found myself dipping on my backswing so I had some spring in my legs for the extension into impact. This led to too many fat shots. I decided to take a more athletic stance with more flex in my legs at the start and things fell nicely into place. No more fat shots! I still hit a few thin shots, but I'd much rather make that mistake. Thanks so much for sharing this game-changing (for me) swing tip!

  8. I just figured this out myself and wondered why I'd never heard anyone teach it this way.  Very good to see confirmation.  I also find that this eliminates my slice.  This is because pushing up on that leg also forces the left hip back and around.  You wouldn't think so.  You'd think the hip would go up.  But because only the left leg is pushing and the hip is actually positioned behind the foot, the pushing motion forces the hip back.

  9. The ground force used in the downswing allows for proper hip rotation and more importantly a Firm left side/leg to post up on. Resulting in better tension lag and allowing proper upper body rotation. Without this concept the body simply continues on it's rotation with no rotary whipping action. Ever snap a towel at you're friend in the locker room? The towel gets it's speed from the stopping forward motion of the towel created by the wrist. Same concept in the swing, as the swing begins it's downswing position the left leg is used in a upward motion to create the upper body/arms/club unit the ability to "whip" through the ball accelerating all the way to the full finish. Great video on the subject

  10. best kept secret in the game.
    Really excellent instruction
    Too bad most golfers are too busy talking and typing than actually learning..
    Really good for me that i don't hang out at the 19th hole and listen to these geniuses…
    Im on the range getting better…🤦‍♂️🤦‍♂️🤦‍♂️

  11. Just wanted to say that this is an amazing drill to really feel centered on the backswing and the left leg rising on the downswing…totally changed how I felt . Thanks Robin

  12. Ive seen a lot (and I mean a LOT) of videos out here on YT, most of which are repetitive, boring and mostly wrong. This man is a breath of fresh air and I just cannot understand why he does not have so many more subscribers. There are so many hacks out here, swing in their living room with a 20 HC thinking they are friggn instructors… oh Please….

    This man is SPOT ON, in every way. His videos are just so well put together and thoughtful and they work!!!

    Thanks so much for providing this to the rest of us, Much appreciated!!!!!!!!!!!!!!

  13. Avoid micro move thoughts, think macro how the body gets to a nice release posture, getting there precludes a billion micro thoughts, none of which we need to "do" or even know are happening, all of which happen without our conscious "doing" them, to get to the nice macro release finish posture. From the top, go to nice finish posture, no "swing" thoughts.

  14. i like this drill very much. however sometimes i feel like the 'pushing up or almost jumping' off the left leg is raising the body up to where its hard to hit down and through the ball…. especially with an iron where im trying to take a divot. im guessing its where one side of the body is pushing up and this in turn pushes the other side of the body down through the swing?
