  1. Actually , I do like these 3-D analysis You Tube videos by Shaun Webb . Now this is cool stuff (below is example video). As Iacus said , won't improve your golf swing but might improve your perception of what is going on in a 'high level' golfer's action.
  2. I've been revisiting this endless belt concept and imho it does seem flawed. If I just imagined I was an adjustable camera that could continue pointing normal to the changing swing plane (ie. formed by the front of the left forearm and clubshaft - left arm flying wedge) from the top of the backswing to impact, the real hand path would look different to these 'face on' views. 1. From the top of the backswing to maybe end of the early downswing (left arm horizontal to the ground, right arm/wrist still still retaining its angles) , the radius of the hand arc would probably be the dista
  3. Pardon me , his full name is Edward A Tischler . I call him Ed as its short for Edward. If TGM is too outdated how about the Tutelman site http://www.tutelman.com/ I forgot to add that if the thread initiator really wanted to delve into the 'Twilight Zone' , there is always Jack Kuykendall website with his alternative views. http://www.kuykendallgolf.com/Members/default.cfm
  4. Reading and watching any golf stuff (whether it looks weird, gimmicky or reasonably sensible) is a bit of a hobby of mine. 1. For learning more about biomechanics - Ed Tischler has some good videos on you-tube . He has also published some books on how to perform various tests to determine your own unique biomechanical patterns. Note: Ed doesn't promote any specific swing but basically says you can find a swing that you can own and fits you. 2. If you want to learn a bit more about TGM (Physics and Geometry of the golf swing) all free of charge then I'd go with Dr Jeffrey Man
  5. I think I now understand where I'm going wrong with COP variances while COG stable. We have moving masses where the COG is stable , but to slow/stop those masses rotating around that COG , one needs to use the legs to brace and slow them down. To do that brace, one needs to push into the ground (to create bracing shear forces). Therefore , even though the ratios of mass around the COG axis are approximately the same, there can be more vertical force pushing between legs/feet and ground and therefore higher COP values. For some reason , that bit of physics has eluded me until now (I seem to ha
  6. I think his distinction between swinging and hitting is quite blurry now. Dr Mann started with a definite no-go with regards mixing hitting and swinging but then he has slowly introduced options. Plus he has revised some of his original comments. example: 1. You must not cock your right wrist Then It is quite permissible to allow a natural cocking of your right wrist, especially if the arms are moving up a steeper plane than the shoulder plane. 2. You must keep your flying wedges intact. Then It is quite acceptable to palmer flex (bow) your left wrist fo
  7. Unfortunately , you have to get acquainted with a lot of 'golfing/anatomical/physics' terms otherwise it will be difficult to understand what he's saying. Examples: p positions, flying wedges, hinge, cocking, dorsiflexion, flexion, adduction, abduction, palmer flexion, neutral grip , power accumulators, pronation, supination, circumduction (I think!). Various muscles and bones in the shoulders , pelvis and legs, centrifugal force (although that is a fictitious force), double-pendulum effects (ie. law of the flail) , anatomical flat left wrist, geometrical flat left wrist, base plane line
  8. It was a real real strain to keep my concentration and I suspect I will forget a lot of it within 1 week.
  9. Well I've managed to view all the videos a third time and I know for certain I cannot perform the swing because I just don't have the flexibility. Dr Mann mentioned in these videos that he personally has virtually zero pelvic/torso separation (ie, his hips/spine/shoulders turn together almost immediately) and has to find another way (just like me). If a high handicapper was aware of the specific movement necessities required to conduct a particular swing instruction ,and was aware of his/her own inabilities to make that move, wouldn't that save him/her a great deal of wasted time and effort p
  10. I'm not interested in him as a golf instructor but I do like listening/reading different opinions on golf mechanics/biomechanics. You've now got me wondering what he was getting wrong? Is it because he is still quoting TGM stuff that may be outdated and superceded by newer analyses/data? PS. I think he got into trouble for rubbishing Lynn Blakes 'Secret of Golf' and that wet mop idea. Lynn Blake said you had to feel some PP3 pressure point throughout the swing but Mann said that was incorrect because of the forward flex of the clubshaft (if you looked at images of the club bend usi
  11. I've never actually tested my swing out to see if it traced the base plane line. I know that Homer Kelley said you need to control the clubshaft, clubhead and clubface. This 'tracing the line' business seems to be something to do with controlling/getting the clubshaft 'On Plane' . So that is 1 of 3 things that must be controlled and (as you've said) will not guarantee a good strike.
  12. Isn't this something that Martin Hall suggested (didn't he start promoting that smartstick)? Good luck with your lessons. Will be interesting to see your before and after videos of your swing.
  13. Remember that Dr Mann is not a golf teacher who can tell you 'how to' , but I suppose he may be able to advise you 'what to' just using his mechanics/biomechanics assumptions (IF you think they are correct but no-one can claim 100% certainty). In parallel with all of this mechanical stuff, I've just read a book by Dr H A Murray (The Golf Secret) written many many years ago and this statement stuck in my head. "It is because professionals have overlooked the fact that most of the details of the golf swing are subconsciously performed, that they are unable to analyse it accurately or
  14. I've started viewing the whole lot for a third time (onto video 4 now again). But then the weather in the UK is so crap that there is nothing else to do rather than shiver. Wait until you get to the 'Sam Snead Squat' move but you may also need to get acquainted with Power Accumulators and Pressure Points which are explained quite well on his website but maybe even better here (by 'The Swing Engineer' - he and Jeff fell out due to some disagreement about Aiming Point). http://www.theswingengineer.com/power_package.html Plus, to fully understand his anatomical explanation of t
  15. From what I have basically gleaned from 15 hours looking at these videos is: 1. Swing intact flying wedges. while: 2. Swinging On Plane (ie, through mostly different inclined planes) - ensuring the 2 ends of the club trace the base plane line while moving through these different inclined planes while 3. Rotating in a barrel plus 4. Learn to keep the clubface perpendicular to the swing plane for at least a few inches post impact. A lot of time is spent explaining different golfing terminologies and anatomical positions plus disagreeing with others about
  16. To be fair, there is quite a lot of important TGM stuff that he disagrees with. Imho , its pretty good but will not really help the recreational golfer who isn't concerned with mechanical swing thoughts. A good starting point for golf academics who want to learn more about the nuts and bolts of a full body golf swing. PS. I think he was banned from Lynn Blakes TGM website because of heated disagreements.
  17. I know @iacas doesn't particularly rate Dr Jeff Mann but has anyone had the time to see his new videos on You Tube (over 6.5 hrs long in total for the 7 videos) ? If yes, what do people think of his assertions?
  18. Many thanks all for your comments. I've actually found a You Tube video that sort of explains it a bit more visually now (more in the later half of the video where he shows his D -Plane model). For higher lofted clubs you can imagine where the blue ball flight will be compared to target line even with a significant variance in 'swing path vs target line'. Sort of explains why my high short pitches/chips (even with an open clubface) feels closer to the target line.
  19. Just a general question as I noticed that I can chip/pitch balls (that are nearer my rear foot at address and with an open clubface) where the initial ball flight direction does not go 80-85% where the clubface is pointing. So a ball position closer to my rear foot and my hands forward at address should mean an 'in to out' swing path . Further , if I open my clubface before gripping (to introduce bounce and lift the leading edge off the ground), the clubface will be even more open into impact and I am expecting the ball to go way right according to the ball flight laws. But that doesn't seem
  20. Many thanks for that reply Iacas (makes sense).
  21. Sorry for resurrecting an old thread but I think the bent left arm is something that could be used to good effect by those who have flexibility issues with regards their shoulder/hip rotation. I've been trying it out and it certainly helps limit the amount of tension I feel in my left lat/arm/shoulder areas. So what are the pros of a bent left arm vs a straight one (imho) ? For bent left arm: pros 1. Less tension in the left side of the body. 2. Seem to be able to make a fuller turn with hips/shoulders because a bent left arm allows right arm to fold more. 3. Any

    So the above video actually proves that some golf instruction could be wrong with regards 'dog wagging the tail'. If the arms/wrists/hands provide 70% of the swing speed, then centripetal forces via the extra pulling of the arms (using the body) after the release starts must be supplying the rest. I've heard that centripetal forces could account for an increase in 20% of the clubhead speed at start of release.

    Hi Savel25 Yes, the first paragraph you referred to was from Tutelman (not me). Your 2nd point about the Kinetic Chain also makes sense but I don't wholly agree with your last sentence " There is no isolating one piece of the kinetic chain. The body does power the swing because you swing with your body. " The body could be moving to accommodate the movement and intention of the arms too. With regards the kinetic chain , I've seen some people hit golf balls while sitting in chairs , etc . but the upper body was still involved somewhat to the intent of the swinging arms (ie.

    Correction below regarding muscle type in younger vs older people (not as clear cut as I thought). Also for sake of accuracy regarding contraction velocities (sorry about the yellow highlights as its a cut and paste) One component of the myosin mole­cule, the so-called heavy chain, deter­mines the functional characteristics of the muscle fiber. In an adult, this heavy chain exists in three different varieties, known as isoforms. These isoforms are designated I, IIa and IIx, as are the fibers that contain them. Type I fibers are also known as slow fibers; type IIa and IIx are referre
