HIP TURN IN THE GOLF SWING how WRONG have we been, the garage sessions in LA

[@scottblencowe6621]

Single most impactful golf instruction video I've seen - First speed training session, never written down more than one 120mph+ swing per session - added nine pencil strokes in my notebook today. Warm beer and soggy chips on me.

[@jeffarmfield2346]

Mark, I gotta say that I absolutely LOVE this series of videos you've done around increasing force by using the force plate. It's taught me soooo much that I've been able to apply to my own swing. I've been tryin to increase my distance specifically on my long irons and, hopefully, a little bit on my driver for about 2 yrs before I found your series with almost no success and I felt like I was flailing around, just as you said. Now, I've finally been able to add that distance because I found out that I was also applying my jump way too late in my swing.

[@jeremylonsdale3350]

Love it. Putting yourself out there as a student after teach for so long is truly a humbling experience. Great to watch your journey. 👍

[@ryang5230]

I have been working on clearing my hips with my coach, to improve path and AoA. That last point about the left knee not being able to move back if it’s shifted to the right is absolute gold!

[@tylerparnell1889]

Maple leafs and Blue Jays Jerseys hanging... Love it!!

[@dancorun6650]

Now I have part two and let me explain. I watched a video you put out awhile ago about the turn and how it led to some swaying and was loosey goosey. You showed the hip turn I call the ski turn which tightened up my backswing and my whole swing. Then this one showed squaring up the left foot when I had been taught to flare it out some. I went out today and squared it up while hitting balls in my net. Wow, I had been striking the ball a lot better since working on the hip turn and now what a difference this move made. I'm striking the ball even better and it feels like my strikes are even more consistent. I can't wait to get out to the course. It shows you never stop improving even at 70. Thank you, Mark. (FYI, I have a bad left knee and squaring up didn't cause any pain at all.)

[@ryanhorner1675]

Fantastic video! I love all the videos that you're getting the lesson. So informative!

[@terrywarner4051]

The Zen training board.

[@Chris-fx8ob]

See Wendel’s number 17, Leafs jersey in background. Great player.

[@leonberkowitz8769]

Great video always thought as a senior golfer that I should flair both feet out. In my youth I was an ardent Hogan advocate so set up with my back foot square but always flailed my lead foot. I have played to single figures but have always fought a pull. Checked my feet flexibility and am able to rotate my lead foot quite easily so no flexibility issues I can think of. My ball striking has improved ten fold since I have squared my feet up and am back playing to singles figures again. Thank you for giving me that ah ha moment. Back to enjoying my golf again

[@barnabyhowe9999]

So so interesting. I’m 5,6 and hit the ball longer than my bigger friends. No idea why but videos like this maybe explain some of the reasons why. By compete fluke I have some decent moves in my swing. I just need to keep the good ones and improve on the not so good ones. Be interested to see what you’re working on next as a result of this session.

[@anthonygollan831]

Mark's videos are my new addiction. Particularly loved this one.

[@epicragegaming2016]

love the wendel clark jersey in the background

[@mattbakergolf]

Love it, think straight line forces in the hips not rotation. Great video Mark always pushing the boundaries.

[@okolekahuna3862]

This vlog was really good.

[@MarkCrossfield]

Thanks

[@michaelreilly5888]

Fascinating discussion Mark! Do more of this sort of thing if you can my friend.

[@thisispw]

Excellent info Mark and well done to Scott for explaining in a clear way.

[@davidharrold9189]

Fascinating information. Great explanation. It’s easy to see how the left foot reacts force to straighten the left leg to push the left hip back and up. It took me a little longer to see how right foot gets pushed forward. I guess the forward movement of the right knee as the bend / flex returns to the right knee tends to try to push the right foot forward. Interesting stuff.

[@legendarysynthesis]

Been watching and enjoying your content for years and this is one of the most interesting videos you have ever made. Fascinating information.

[@charlesmarshall8046]

This stuffis really interesting and informative. Much much more worthwhile than the course vlogs.

[@Boerkreeelis]

Very interesting video, love his explanations. It's a very intuitive way of processing golf movement, I like it.

[@stevenhocking7731]

Love these videos Mark. So much to learn. Although it does frustrate me that I learned golf when all the information and teaching was the opposite of what we know now.

[@Alan_Edwards]

I agree. Wish we had this tech when I started learning golf 40 years ago. Well at least I can take advantage of it now anyway.

[@rp6163]

Data from dual plates very interesting and impactful. Terrific video gentlemen

[@6daymember]

I am likely just a bit slow but have never really understood what some youtube coaching were sating when taking about getting the force "down" or "into the ground". That just encouraged me to swing harder from the shoulders into the ground (and all the problems that entails...). So this is really helpful in understanding that its more about the feet than the upper body. Or at least i think that's what's being said!

[@correiaguerreiro]

Obrigado!

[@leftoff77]

Mark, I'm not a fan of hyperbole, but the way this video presents the concept of shear force is borderline transformational. I know this isn't a new idea, and I've seen it presented in different ways by others - namely I can remember a drill by Larry Cheung where he wants the back foot to feel like it's slipping out, and feel like Peter Cowen's Pyramid concept is getting at this in combination with vertical ground force (thought it is overly complex and mechanistic to me), but this is the Occam's Razor presentation - simple and scientific. This is really your coaching and exploration of the golf swing at its best. Challenging status quo ideas in irreverent way but doing so with data informed analysis - truly in the scientific spirit. And love that you're introducing people like Scott to a lay audience who does a wonderful job of breaking down complex ideas into understandable language. A few amazing ahas this video revealed: how lateral movement of the left knee (for righthander) can create problems, and depth is more important for shear force than lateral; how in general Scott notes that increasing shear force leads to better golf shots as golf is inherently a rotational game - it may be a hard concept to grasp, but interesting that it is perhaps the place to start to improve speed and quality of contact without too much downside; the bit about how foot flare may hinder maximizing or creating effective shear force; and in total how shear force as a ground force in essence is the genesis for good hip rotation was a real eye opener for me. Went to the range applying this ideas and was blown away by contact and feeling of power in my strikes, but also how relatively effortless it felt as I'm prone to overactive upper body (and was interested in this to help address a tendency to pull due to shoulders and arms overtaking my lower body). Surely I'll find some new things to struggle with, but honestly this was a revelation for how I think about the swing and really do think it comes down to your inquisitiveness Mark and ability to combine deep analytical methods with accessible language, openness to new ideas, and belief that no idea is too sacred to put under the lens of a force-plate : )

[@JonathanMargrave]

Great content Mark thank you. Don't think coaches emphasise the rotational element enough rather they obsess about positions. Also doubt Scott would stand where he was if I was hitting balls after some coaching! 😀

[@georgeowens582]

Took me a bit to initially catch on to the terms and how how they related, but so well done. The last part of the video with him pushing against the back of your left calf/knee was the light bulb on moment. Also like to see a somewhat messy garage. 🥹. Thanks for the great video.

[@Geep1778]

I was doing a similar thing on the range yesterday and it was a nightmare lol. Trying to be conscious about increasing how you rotate to make more power screws up everything else in the swing. You have to do something tailored to increasing your body’s speed or stability without realizing it will help golf. Like it’s in your mind as you do it but the results aren’t immediate. It’s like in the karate kid when he’s painting the fence wondering how this bs makes him a fighter. We know It’s works out but he doesn’t until later on.

[@Fetchem1222]

Another 💎 gem! If I can call you out. I must call you up for a bow. Stellar content explaining difficult terms in auditory and visual ways. Great props! Excellent video Mark!

[@jayschultz7395]

Welcome to Redondo Beach, if I knew you were coming we could have had lunch or played a round of golf. Hope you enjoyed your stay.

[@ajaytuk7416]

well well well, awesome for us golf geeks- I must say I have struggled with your vertical jumping ( apologies if I get the terms wrong), but combine this with the torque concept it makes much better sense- it sort of blends everything together. I don't have access to any force plate stuff- is there any swing thoughts that can help. For example, the pushing off the left foot it felt like it just pushed my weight back to my right foot ( Im right handed)- and coincidentally an it made it difficult in my mind to get the torque forces, in fact my follow through finished much higher and definitely put more pressure on my back- a more reverse C type finish. I was starting to abandon this experiment, but seeing this rotational/torque element I can see a much clearer path forward. I am probably in a small group, I am well into my late 60s, I am a cat 1 golfer still, my body hurts a lot but I would still like to improve my distance, or at least maintain it for as long as possible. I cant wait for the next episode!

[@wordclouds2906]

I think 'clockwise' and 'counterclockwise' when I practice this. Each fore foot is the minute hand on a clock. I just turn the minute arm from lets say from 00:30 to 16:30 on the trail foot during the downswing - in response the body rotates. Direction and magnitude of the force vectors is not difficult; it is simply a push-jump with a 1/4 turn towards the target while keeping the center in place. The difficulty lies in the timing: right foot starts pushing towards target before the backswing is complete (separation) and turns vertical before impact; left foot counteracts and pushes up, starting before the shaft is in the horizontal, as well with max before impact. You feel it best in the balls and bones of the big toes (get off the heels to feel it; keep a positive shin angle of the trail leg). My guess is that people who start the downswing with their arms might be late with either foot. Quite important: the better the posture ( bend in the hips, shoulder blades together, belly in etc.) and the more passive the upper body in the swing the easier this foot driven motion is. Practice barefoot.

[@MA-jx9um]

Interesting Video, lots of science to absorb, the take away for me is the feeling of torque and foot position, relative to body position. Thanks

[@ReinoutSchotman]

Being an engineer myself, this makes a lot of sense. Thanks Mark!

[@alistairsmith3167]

very informative theres always something i can work on with my golf swing. thnx again Mark

[@SolomonLi]

So interesting…. And so glad you made it out to Redondo Beach! Lots of cool stuff going on in this video.

[@sevenoranges]

I need to see this series of videos over and over again. So a feeling of casting is "good" as long as my clubhead does not pass my hands by impact?

[@terrywarner4051]

Please forgive me if i'm wrong but Zen golf have been teaching this move for a long long time, just have lesson with them.

[@douggrant6643]

Superb, exactly what I'm playing about with. Really helpful

[@johnmorpuss1105]

I remember the "power move" as Mark called it and still use it today when warming up , raising the left heal and snapping it back down at the top of the down swing really gets the left side out the way . Keeping right elbow inside of right hip can be a worry because the arms have to keep up with the legs, your timing can be a little out and lots of weird thing can happen like your whole body wants to face the target because your left knee snaps back so hard .The metres gained on cause has help bring my handicap down, now hitting wedges into greens instead of 7's and 8's. Every now and then it's good to bring the power move out on those long par 5's and just smash it. FOR RIGHT

[@truthdragon7719]

Ive started playing golf in my garage now, membership is free, I only need one ball and I don't need my trolley. Its a win-win-win. Ive also made some graphs, mainly based on club rafter interaction. I call it clank to strike rebound ratio analysis.

[@JohnDunigan]

Great Video! Scott Lynn really knows his stuff!

[@stuartward8612]

Amazing information love to know how to put that into a golf swing

[@legend9018]

So good, this information is the missing piece as to why you can produce different distances on swings of similar speed that feel the same and have similar strike. The timing of that push is critical.

[@kentturner595]

This is so freakin awesome!! Thanks for sharing this, Mark

[@TeddyCavachon]

Something you might want to experiment with is to flare feet inside of your shoes at address to pre-torque the legs. It is a trick I first saw Steve Elkington mention in one of his videos and trying it I found it made a significant difference in my swing for the better.

[@anothergolflesson]

Great video Mark. Very interesting. Looking like Scott is a Leaf fan on top everything else which is a good thing too.

[@markreider9663]

Very interesting but very technical. Mark, for those of us who can’t get this kind of analysis, please tell us what you were trying to do and what you were feeling during the swing adjustments. And welcome to California!!

[@travellingmojo]

Great insight. Amazing how technology can help with forging new swings. Also appreciate that Scott is a Leafs fan. Must be a Canadian living in the US.

[@TRI5T4N]

Great video. One of your best. Fascinating insight 👍

[@Mickelmus1]

Evening coach, I struggle with downswing and impact especially lack of rotation. Does anything you do on the force plates affect early extension sort of impact conditions? Love ya ambassador

[@publicnmy147]

Pure gold for nerds like me. Love it.

[@adamvlassis4090]

You walked passed my friends old apartment on redondo! I’ll keep working my pins and get those vertices up

[@robertsinclair7901]

Shout out to the Wendel Clark jersey! Love the videos.

[@SeemplesCL55]

Interesting video, pushing with the feet sounds to me like trying to hit the ball with your body? I was always 'force fed' hit the ball with your shoulders, arms the the correct grip will naturally release the club head enabling your body to follow...... Given I'm now awaiting a replacement right hip I understand this as it is the only way I can produce club-head speed and still get the ball out there. No doubt after my operation I'll have more mobility so may need some lessons however I've now found the whole golf swing much easier (less effort) and may not necessarily look to drive too much with my legs, time will tell!

[@RickysmobilebodyworkinLaPuent]

hello Mark Crossfield I've been waiting for you to come to California love to have a cup of coffee with you and talk a little bit about golf thanks for your help really appreciate it you helped my game

[@stevenkur6267]

Amazing video. Mesmerising stuff, great work 👍

[@steveadkins9456]

Great stuff, Mark. So the point you guys made about torque and keeping your knee more over your foot, does that lean towards keeping that left heel down?

[@wordclouds2906]

Percy Boomer 'On Learning Golf', 1942, for correct timing of the foot work. Best golf book available. One of the principles of Percy Boomer is that the feet never stand still and they are always ahead in the movements. Interesting to see how little golf teachers seem to understand of what they are supposed to teach. :) (I am not an expert, just referring to Percy Boomer). Referring to Percy Boomer, your waggle is 'wrong', Mark; it sets you up for an arm dominated swing. The waggle should be a response to the rotation of the body, not wrist action, not independent, not leading the body. I think foot work ( timing, magnitude and direction of the force vectors) should be the main and essential basic training for a golf swing.

[@DanB-]

Amazing insight into the forces!

[@royclose946]

Well done mark just come back from torquay n the coarse there is excellent 👏 👍

[@groende]

Great video. Even better with all the Toronto jerseys. Assuming that was a Clark sweater (would prefer Sittler tbh)

[@DjSidewayz07]

Absolutely great stuff Mark, I love the nerdy details. I wonder if you could briefly explain to us (maybe in a video) what we might be doing at the range if the mat is rotating anticlockwise after a couple dozen shots. As a right handed golfer, I’m would expect my left foot to push the mat, or is it the weight of the left foot coming back down that’s moving the mat? 🤔…. Either way been a fan for a long long time, I appreciate how you’ve continued to progress and inform us with the newest available info 🤙

[@steveblewer1202]

Sorry Mark I'm lost with that one. New golfer, and I'm bearly managing to compress the ball consistently lol. I'm sure there are things in that video that I could apply, but my mind is already clogged with tonnes of stuff, just trying to take the club back correctly. Maybe later down the line lol

[@cpOtAto]

Question: isn’t turning the nut with the spanner partly using greater force because you’re using your whole arm and shoulder? Just wondering how much extra force you could gain using the spanner with the same amount of force as your fingers exerted.

[@Storm-gt3kg]

Hey mark could you explain about where each foot percentage “should feel like”in during certain parts of the swing I’m struggling to get in sequence with these ideas thanks for the videos!

[@prospetiva3d]

Another Great Video ! Oh and welcome to SoCal!!

[@cartersmithgolf]

always interesting. a great journey of discovery.

[@Mr.Bill-cnd]

Great video with loads to think about, especially how it is Scott is such a fan of the TMLs. Formerly a Torontonian I guess.

[@sandraandgraham57]

Food for thought, excellent video Mark. Watched it twice now with more to come just to try and understand bits of it..... I think this is going to give me a massive headache 😱

[@SupeDefy]

If timed correctly, I can literally jump and move my front foot away from the ball at the poc. It means I've "pushed off the ground" before poc, maximizing the vertical forces. Basically do what Kyle Berkshire and Bubba Watson does. They literally jump and move their front foot way from the ball by about a foot. Can't do that if vertical and sheer forces are not timed well.

[@Burkeyboy77]

I love his analogies

[@sirtogii5216]

Absolutely love this, certified golf nerd I guess....

[@toddlittle926]

Really impressive learning

[@arjanpetersen]

Amazing how consistent Marc is.

[@jamiesloan7259]

I think the plane of your swing would affect these pressures. If you have a steeper, or more upright, swing(or plane), you’ll obviously feel more vertical force(Justin Thomas, Scotty Scheffler). You can actually see these guys almost jump up through impact. And, just the opposite…. Someone that swings the club “flatter”, will obviously feel more of the torque forces. Am I correct in thinking this?

[@ianburton9223]

Relational and reasonable physics that I can follow. How to put all this into muscle applications of a golf swing was extremely difficult if not impossible to grasp. So how valuable is information that have no way of using? Do we all need to go to this guy's garage?

[@lucmoulonguet]

J’ai jamais fait autant de progrès dans mon swing que depuis que je me concentre sur le travail de mes hanches et mon bassin, c’est pourtant très rare de voir des enseignants s’y consacrer….

[@glenndavenport9077]

Tried it today when playing but I felt right hip pain after a while ? Feels like all your weight is on right side while shifting left foot out the way ? Hit some bigger shots at times though

[@alanlovesgolf3462]

Love this video Mark. So interesting, I’m a physicist and if I had my time again I think I would go all in on bio-mechanics. Just brilliant.

[@fyimediaworld]

Dude's a Leafs fan. Good job. Wonder if he's teaching them to play golf after they blow their first round playoff series?

[@LongNguyen-vb4ng]

I live close to redondo, how can we get a analysis of our swing?

[@thombendtsen399]

Mark, is the vertical force and the sheer force the same thing? One force going up and back diagonally with the left side? Or are these 2 different things?

[@SupeDefy]

The way I understood it is 2 diff things. Sheer force is the force on front leg/foot moving away from the ball and back leg/foot moving towards the ball. Sheer force creates torque. Add vertical force and you have the source of power and room for the arms. In practice, when timed correctly, your front foot could literally be in the air at the point of contact because you've already "pushed off the ground" maximizing vertical force. Justin Thomas is master at this. His left foot is literally off the ground at point of contact when he is going after it on the tee box.

[@FredzGolf]

Love this! too easy to go for the low hanging fruit haha Absolutely agree that strike and all sorts fall apart when the vertical movements are increased ...the rotational nature is harder to achieve but better results long term Need me some plates!

[@andymat7359]

This new tech is amazing, I could really do with someone explaining in layman terms how to feel the ideal loading of weight throughout the swing with longer irons and woods, I'm having difficulty visualising where and when each leg should be pushing. Also that net's a tad small, I could see myself duck hooking straight through that window. 😂🦆

[@saintpatrick6681]

the British swing room are so bloody fancy compared to the garage swing man.
