  1. I'm just checking it out on Amazon - seems to have some good reviews so might be worth a purchase. From what I gather , all pro golfers seem to flex their lead wrist sometime in their golf swing . If it's to help square the clubface by impact , I can only assume that it must be done while its in radial deviation (either later in the backswing or early downswing) . If that's the case and they retain some of that flex while moving into ulnar deviation , there will be some opening of the clubface relative to the ball target line . But the net effect must be some clubface closure and more close
  2. This thread is about biomechanics of left wrist flexing not about golf practice, breaking 80 , etc . As I said before , if you want to inform other forum members about your ideas and the 'basics' as you interpret them , you are quite welcome to create your own thread.
  3. The answer is yes when the lead wrist is in radial deviation but no when it's in ulnar deviation.
  4. Monte's instruction actually changed the hand path of Brendon . If you look at the images below , his 'Before' hand path became more curved quite early in the swing because of upper body moving targetwards . His lead shoulder joint pulled on his arm too much/soon targetwards and that cause the club to release early. By shortening the swing he could time the release so that clubhead speed peaked closer to impact.
  5. Why not create your own thread to show how simple the golf swing is and then people can debate the pros and cons?
  6. Does it flatten the clubshaft swing plane (ie. decrease its angle to the horizontal) or just shift the plane down a bit (ie. no change in the angle to the horizontal)?
  7. This thread has nothing to do with my golf swing or whether one can or can't consciously flex/extend . It's a question regarding the biomechanics of the move and how it might affect the clubshaft/clubface. For example , I've heard that flexing the lead wrist closes the clubface , is that true or false?
  8. I'm not advocating actively flexing and extending the lead wrist, just pointing out the possible effects on clubshaft and clubface if you do it when in ulnar/radial deviation . If I was at the range , how would I measure how much I was flexing and extending the wrists and the instantaneous amount of radial and ulnar deviation? Also how would I know at what point in my swing (especially downswing) I was doing all these actions? Although I might give it a go after lockdown and see what happens (as an experiment) .
  9. There are many qualitative concepts that pick and choose aspects of physics to try and validate their claims . Further , there are many theories out there that use 'medical experts' to claim their swing concepts are better for your back . For example , the use of the Double-pendulum and Centrifugal force to explain the generation of clubhead speed is easier for golfers to grasp rather than 'Hand Couples', 'Net Linear Force' and the 'Moment Of Force' (caused by that 'Net Force'). Depends on how much you want to go 'down the rabbit hole'. Further, I've seen mention in
  10. This thread was really about the biomechanics of wrist flexing and not general golf instruction . As I mentioned in another thread I have a golf book with 47 different qualitative theories on the golf swing so pick whatever you think works for you (the book is titled 'The Secret Of Golf' by Georg Peper). For me personally , I would rather look at the physics of what's going on first and then use whatever was the best model for replicating the correct physics. In this specific case I wanted to find out the reasoning behind golf instruction that promotes flexing of th
  11. Yes, that is currently impossible to fathom with 100% accuracy although Choi has attempted to work out the kinetics of body segments using some model. It's the best we have at the moment to determine what forces/torques are being applied to the grip by pro golfers but its certainly not just along the clubshaft (although that might be a good 'feel' for whatever qualitative concept you think is superior to any other).
  12. A golf club cannot accelerate in a curved path just under its own angular momentum , there needs to be a torque or 'Moment of Force'. Torque = Moment Of Inertia x Angular Acceleration Just like an object moving in a straight line under its momentum , there needs to be linear force to increase its velocity Force = Mass x acceleration One cannot 100% confirm what is the source of the force/torque applied via the hands on the golf club (ie. it could be body movements or even from the wrists themselves or a combination). Also , the gra
  13. External focus on an intended task is a good way to learn/retain motor-learning skills but as I've said before , if you know quantitatively what commonalities are happening in good golfers golf swings , then golf instruction can follow some sort of model instead of the plethora of qualitative concepts out there . TGM, Rotary Swing , One Plane/Two Plane, Double-Pendulum , Triple-Pendulum, Trebuchet , Catapult , Gravity swing , Square to Square, Single Axis , Morad, Lesley-King (left arm swing - reactive pivot ), Leadbetter 'Dog Wagging The Tail' , Connected Swing, etc etc .
