  1. If your swing works okay and getting fair distance and accuracy , I wouldn't fiddle around with it too much. Seems like you really do whip it through so I guess your clubhead speed is pretty good. If you want a bit more hip turn , then maybe it could be just a simple fix like narrowing your stance (it looks quite wide but difficult to see from a DTL view). Your current swing doesn't seem to be using any pivot to create hand speed and I think you are using your left shoulder girdle muscles to help pull your left arm down. However, you are adducting your right upper arm while pitching your right elbow just above your hip very assertively. It looks like you are using your right arm more to push your left arm down and out towards the ball. I'm unsure but you could be categorised as a 'right arm swinger' but missing the pivot part. Tom Tomasello actually taught a right arm golf swing, so it might be worthwhile reviewing all his videos.
  2. There is a possible explanation for that straight path but its a set of moves that I cannot do without being put into traction . Cameron Champ does it too: Look at : a. Their left shoulder b. Their upper right arm c. Their right lateral side bend d. Their right elbow. To get that straight path they do the below almost simultaneously: 1. Pull their left shoulder towards target (this helps brings their left arm down) 2. Adduct their upper right arm towards their right side ( also helps bring the left arm down) 3. Pitch their right elbow towards their right hip (shallows their downswing plane and also stops their right arm getting blocked behind their torso) 4. Perform a lateral side bend (also helps shallow the downswing plane ) Basically , both DJ and Cameron are performing moves that help create that straighter downswing path and also shallow out their downswing planes (at the same time). So much more complex and requires great flexibility but also puts a great deal of strain on the spine. Bobby Jones didn't do the above and I can imagine he never had too many back problems, contrary to what I've heard about Cameron Champ who is already suffering bulging discs at such a young age. PS. Just been looking at Wikipedia about Bobby Jones to see if he did have back problems as a player . He actually died of a back related disorder. What a sad tragic end for him and his family: Incapacity and death In 1948, Jones was diagnosed with syringomyelia, a fluid-filled cavity in the spinal cord that causes crippling pain, then paralysis; he was eventually restricted to a wheelchair. He died in Atlanta on December 18, 1971, three days after converting to Catholicism. Jones was baptized on his deathbed by Monsignor John D. Stapleton, pastor of the Cathedral of Christ the King in Atlanta, and attended by the Jones family was buried in Atlanta's historic Oakland Cemetery. Jones was inducted into the World Golf Hall of Fame in 1974. His widow Mary died less than four years later in 1975 at age 72, following the death of their son, Robert T. Jones III, of a heart attack in 1973 at age 47.Daughter Clara died in 1994 at age 68.
  3. This is again for those mainly interested in the biomechanics of the golf swing (ie. what is going on rather than how). Just thought it might interest others who are trying to figure out what many of the pros are doing to drive that ball 300+ yards. Lets use DJ as an example about optimising clubhead speed. The secret to his high clubhead speed seems to fit in with physics. 1. From Image 1 to just before image 3 , he has somehow made biomechanical movements that have created a hand path on a 'straightish' path (or an arc with a long radius). 2. Along this 'straightish' path , he has increased his hand speed as much as he can. 3. He has retained left 'wrist cock' angle (angle between shaft and forearm) from top of backswing to just before image 3 (where one can see the 'release' of that angle happening- increasing). Physics proves that more wrist cock before a 'natural' release , the faster the clubhead speed. 4. The 'natural release' of that angle happens due to 'pseudo CF forces', because he has performed biomechanical moves that change his hand path from straightish to a more curved path. His wrists just before image 3 act as oily hinges and he is basically letting the 'momentum' of the clubhead (ie. evoked by pseudo Centrifugal Forces) uncock his wrists (ie. a natural release). A simple 'imperfect' analogy of point 4 is like driving in a car (ie. your hands) on a straight road increasing your speed and then taking a very tight corner turn. Any objects (ie. the clubhead ) in the back seat will go sliding across the seat very fast. The counterintuitive part is that his 'wrists/hands' end up actually restricting the 'angular velocity' of the clubhead because it is rotating faster than the hands can keep up. This is proven by physics which says that forward shaft bend into impact means 'negative torque' at the hands (see image below). So now we know what DJ's hands are doing , the puzzle is figuring out 'how' he is moving his body parts to create the dynamics and geometry of his 'hand speed/path'. Obviously , the above is just about creating clubhead speed and not the biomechanics involved in squaring the clubface (a different matter altogether). So has anyone got any ideas how DJ creates that straight path in the downswing? PS. I thought it would be a good idea to show the hand path of Bobby Jones (in red below) which shows a more circular hand path , where he also had an 'earlier' natural release. He couldn't replicate the hand path of DJ because of the limitations on the strength of hickory shafts . If he tried stressing the shaft using DJ's hand path (ie. straight path and then speedy acute 'corner turn') the shaft would have broken.
  4. Basically , you can have all the correct geometry in your swing, correct posture, wrist cock , swing plane, centre of swing stable, etc . But if you don't swing with a rhythm that matches your own 'body/club' unit frequency, you will still struggle. It's like pushing a kid on a swing , you have to match the pushing to the swinging frequency of the 'kid/swing' system. Same with golf , you have to somehow tune into your own swing frequency (ie. subconsciously , not something consciously manipulated). I am guessing that one can identify your unique biomechanical frequency by just swinging in perpetuity without strain and in balance until you can easily hear the whoosh of the clubhead just after an imaginary impact . Then do the same for all the clubs in your bag using a metronome and check whether swing time is approx constant. Good video below but imho, Peter Finch should not be advocating 'internal focus' cues about your hips and weight pressure transfer to your lead leg. Maybe better to use 'external' focus cues (ie. not directly related to a body part) , like pushing into the ground while getting your belt buckle turning out of the way.
  5. This is what swinging in resonance can do to you. I remember seeing this at college where our lecturer said the crosswind was blowing at just the right frequency that matched Tacoma Bridge's own natural frequency. Now imagine if you did the same for your golf swing - Kabooom !!!
  6. Thought this might be interesting to golf biomechanic nerds like me. According to this Professor, research shows that PGA pros (and very good golfers) drive their bodies in resonance like an harmonic oscillator. They have perfected a biomechanical clock which means they have superb rhythm and tempo. Full Swing : Backswing should take 3 times longer than downswing 3:1 ratio I've just skimmed through his research papers on Putting https://arxiv.org/ftp/arxiv/papers/0903/0903.1762.pdf Same amount of impulsive force used to get the backswing and downswing going but the frequency of the putt is twice the resonant frequency of the body/club unit pendulum. Backswing takes twice as long as the downswing 2:1 ratio. Note that you apply the impulsive downswing force just before the backswing ends, so you can get a sense of the direction the downswing should progress (by pushing against the inertia of the backswing). He quoted Zen Golf at the end of the video but then reinterprets what they say using physics terminology. So swing perpetually and get your metronome's out
  7. Here's another technique (not a bad website for learning golf basics and terminology). https://golf-info-guide.com/video-golf-tips/should-i-hinge-my-wrists-more-when-chipping-at-golf-video/ But as soon as one finds someone who discounts one method (ie. wrist flipping) , there is always another golfer who excelled in it (see Count Yogi's style below - the complete opposite). https://www.youtube.com/watch?v=Z5yHmlHSAsg And here's another few: Ben Hogan Chipping style (the description of how to do it is at the end of the video) There seems to be a variety of chipping opinions : 1. Restrict wrist movement to improve a theoretically opinionated technique . But no real detail of 'how' to perform the stroke (ie. from a biomechanics perspective). 2. Allow natural wrist movement (again no details on the 'how' to perform the stroke) 3. A mix of both How about focusing on your intended outcome and just letting your body find the best way to meet that intent? Is that a worthwhile proposition or will 'fear' just creep in and short circuit everything?
  8. I read the same thing from Golf Digest link below but when I look at Freds swing, it doesn't look like 19 inches. https://www.golfdigest.com/story/couples To me, that move makes Fred the athlete/golfer," says instructor Jim McLean, who after measuring more than 200 PGA Tour pros found that Couples and John Daly moved the left hip the greatest distance forward on the downswing: 19 inches -- a full six inches farther than the tour average. Got to be careful here , because the actual 'lateral movement' is just a reaction to keeping your rear hip stationary in space at the end of the backswing. So the lateral movement actually happens in the backswing. Here is Shawn Clement explaining what I've just said above (he calls it the 'Hogan Power Move'). PS. Whatever 'net ' lateral movement happens before impact , just ensure that you don't start your downswing by moving weight pressure immediately onto your lead leg/hip. I mean how can you stabilise the rear hip/leg in space if you've immediately moved the weight pressure off it? Imho, just keep the weight pressure on your rear hip/leg momentarily until a little later in the downswing before doing any weight pressure transfer to the lead leg. But I'm afraid it all has to be done subconsciously, so you need to ingrain it somehow by drills , etc.
  9. My Good Books: Search For The Perfect Swing - Cochran & Stobbs - Best book I've read regarding the science of the golf swing (although it contains some errors in their defined wrist actions). Most of the content is still applicable today even though we have high tech 3D systems. How to Become A Complete Golfer - Toski & Flick - Got lots of practice drills in this book Secrets Of Owning Your Swing - Edward A Tischler - How body structure influences the mechanics of your golf stroke . I haven't bought his new books yet which provide tests to identify your unique biomechanical pattern for performing the golf swing (dependent upon whether you are a 'Thrower', 'Hitter' or 'Swinger). The Swing Factory - Sieghart , Gould & Wilkinson - Based on the Leslie King swing method - the body does not propel the arms but reacts to the swinging arms (similar to Toski and Flick opinions) Play Better Golf - Beverley Lewis - Best practical book on 'how' to execute the long and short game with fantastic illustrations. Swing Like A Pro - Dr Ralph Mann - Found commonalities on a study of the swing of many tour golfers - then created a 3D pro model (that could be tweaked for different body types ) performing their 'perfect' swings. My Bad Books: The Stack And Tilt Swing - Bennett & Plumber - Hurt my back trying this method so I hate it!!! The Single Plane Golf Swing - Todd Graves - just a load of vague confusing instructions that make no logical sense at all. Nice pictures and comments about Moe Norman Other Books : The Golf Secret - Dr H A Murray - anatomical explanation of the golf swing (dated 1976) The Secret Of Golf - George Peper - History of different opinions (from 376 different teachers/golfers/theorists ) regarding golf instruction
  10. Yes, I tried doing this 'Drive Hold' type of hand release and couldn't do it because I just wasn't flexible enough. To do it successfully you have to get your right shoulder closer to the ball so that you 'don't' run out of right arm through impact (ie. keep your right wrist bent and not allow it to flip through impact). And to get your right shoulder down and closer to the ball you need to have a lot of secondary tilt while you rotate your torso and that really started to hurt my lower back. If you check out Reed and Michelson , they don't have as much secondary tilt and 'lateral bend' like Cameron Champ ('Drive Holder') and are probably minimizing strain on their lumbar spine.
  11. Won't a crossover hand release be very timing dependent? I mean if the clubface is rotating rapidly , your timing to get the clubface square by impact will need to be perfect. PS. Interesting snapshot of Patrick reed below at 0:59. His right hand has come off the grip because he's run out of right arm (just like Phil Mickelson, but obviously being a lefty, it would be his left arm).
  12. I have confused you with my previous post (which I have now edited - too much 'biomechanics' stuff) but I do find some of Shawn Clement ideas successful especially if I don't have the time to ingrain 'theoretic' golf mechanics into my game (without any guarantee of them working- Lol! ). Get yourself a 'Grass Whip' and learn how to cut grass using something he labels 'The Perpetual Motion Drill'. Or you practice with your normal club something called the 'Elephant Walk' hitting a line of balls (or tee pegs)
  13. Hand 'speed/path' dictates the evoking of the 'fictitious - Centrifugal Force' . Holding the lag is difficult to do because the 'CF ' force amount generated (if you are moving your hands fast in a tight arc- see image 3 for Jon Rahm) increases so much that you cannot 'hold' the lag . The 'inertial forces' you start feeling through the hands/arms is similar to swinging a bag of heavy cement (ie. 100 Newtons approaching impact). Trying to hold the wrist cock and releasing later (ie. allowing the free unhinging of your wrists as your hand path moves into a tight arc) in the downswing will no doubt increase your clubhead speed but then you still need to find a way to square the clubface by time of impact. So what I'm saying is by changing your release, you might also need to change other mechanics in your swing so that it all fits together. PS. Another cause of excessive forward shaft lean by impact is if your upper body moves too much laterally. The centre of the rotation of your swing will move to the lead shoulder joint by impact. If you move your upper body forward towards target ,this also moves your lead shoulder joint which will create a tendency to have too much forward shaft lean.
  14. I use 'Goldilocks' for my distance control (and I still suck!) but there is no substitute for practice playing in lots of different conditions and then gaining some intuitive feel for how the ball is going to react to your intent. You can learn mechanically by practicing where your hands are until its ingrained in your subconscious but there is danger you might use 'internal focus' if you think about body parts during your round (ie. thinking about where your hands need to be). Internal focus 'short circuits' your kinetic chain. Check this out by Shawn Clement .
