  1. Here is Brendon Devore demonstrating a training aid called the GEM which he regards as one of the best he's tested out. https://www.youtube.com/watch?v=9b3e1IuzmyA All I could think of regarding the physics being used was that the attached 'rod/metal ball' weight creates a moment of force about the axis of the shaft (in the early downswing as shown in image 1 below) that would tend to assist in closing the clubface from P6-P7 and through to P8 (if you don't interfere with its natural tendency to reach some equilibrium position under the force of gravity).
  2. Interesting article by MGS. https://mygolfspy.com/study-accuracy-versus-distance/
  3. I've never played Hockey (I'm assuming you mean Ice-Hockey) but isn't a slap shot where you exert pressure on the ice just before the puck creating 'lagging' strain on the shaft before you release that strain energy into the puck (while the shaft is still in lagging bend)? That type of 'release' action is not what happens in a real golf swing because the shaft is in forward bend before impact as in gif below. The broom drill might help with some other arm/body actions but imho it will not help your hand release actions. Golfers need to decide for themselves whether they want to ingrain the good with the bad.
  4. Feet together drill is what I used to do (and still do) but you need to do it properly. Shawn Clement demonstrated this 14 years ago and transformed my perception of the golf swing. He even got the physics 'intuitively' correct in some pragmatic fashion. https://www.youtube.com/watch?v=wTZ-2C-O0u8 His recent video with his daughter shows some good drills too https://www.youtube.com/watch?v=hfGz9VdlwK0
  5. Here is Adam Young as guest on 'Be Better Golf' which might be of interest. https://www.youtube.com/watch?v=XxlNeORi7ik
  6. Yes, we are different. I gave up on positional and specific movements about 8 years ago and I don't just swing without an intent (that won't work for me at all). You have to train yourself to feel the motion that matches your pictured intent and it's very difficult to master. I prefer a neutral grip, I do my best to keep a neutral spine, balance point in-between my arches, conduct perpetual rhythmical motion swings (to a target) without excessive strain and see/feel how my clubface path and orientation brushes the turf. I then use that feedback to align my body and ball position such that my actual golf swing (which should feel like a replication of my perpetual golf swing) meets my intent. Maybe the use of my legs to create pressure/weight shifts is something natural that I learned when playing sports at school but I never utilised them when trying to learn golf using the 'expert' instruction books/videos of 30 years ago. When I started using external focus cues, I couldn't believe how active my legs were and the whole swing felt unusually 'out of control' because I was so used to musculature manipulation feels using specific movements and positions. There were times when I thought it would never work and gave up for a few months reverting back temporarily to theorised positional movements. I persevered with external focus cues and its fine for me, just a recreational golfer, but maybe your goals need a lot more refinement in your golf swing mechanics.
  7. Personally, I toss the club in my backswing with a strong focus intent to swing to target and my driving is pretty good (no complicated biomechanics in my golf swing). For example: 1. I leave a set of old golf clubs with a golf friend and travel by train to his local golf course to play approx 6 times a year. 2. Never practice or visit a range (there aren't any close to where I live- especially if you don't drive a car) 3. Played at St Omer golf course in France 3 weeks ago (it's a very demanding/difficult course) with a set of clubs and driver that I haven't touched for 4 years. Drove the ball very well except for 3 wayward strikes over 36 holes . Distance and accuracy was comparable with another golfing friend who is a 7 hcp and drives the ball 250 yards (he only uses a 5 wood). My short game was terrible as expected if you don't practice for distance control feel. From my own experience, there is nothing better than external focus intent when you swing a golf club and once you've mastered that it's like riding a bicycle (seems ingrained and you never forget). Try external focus for about 6 months (and I mean stick with it) and you will never need to buy any videos again.
  8. The 'Kinetic Sequence' and quite an interesting analysis of the GRFs being used in Justin Rose's swing. https://swingcatalyst.com/articles/the-kinetic-sequence/
  9. HK seems to have mentioned 3 essentials. http://www.theswingengineer.com/essentials.html Apparently without the 3 essentials you'd have trouble with the imperatives. http://www.theswingengineer.com/imperatives.html
  10. Some interesting videos by the 'TheSwingEngineer' showing Homer Kelley's Power Accumulator concepts. https://www.youtube.com/watch?v=kLmovcDc49Q&t=117s https://www.youtube.com/watch?v=RgJly-Rr2Og https://www.youtube.com/watch?v=HlXdMW3v0ks https://www.youtube.com/watch?v=zmNKyiPclkI&t=79s https://www.youtube.com/watch?v=C9xT71yc8xI
  11. Interesting video using this Sportsbox AI tool. Dr Phil Cheetham provides a nice simple explanation on how pelvis lift is being used to increase clubhead speed. Dana Dahlquist provides some ideas on how to put golfers into various 'buckets' depending on their abilities but imho this AI tool can evolve to do some fantastic things in the future as they collect/load more golf swing data. https://youtu.be/DRVvE8WiuE8
  12. There's nothing wrong with a cupped/extended lead wrist at the top of the backswing if you don't overdo it, such as allowing your wrist joint to collapse into some maximum extended position. If you grasp the grip there is a natural 'cupping look' even though your wrist joint is basically neutral and not actively in extension, plus the average Tour Pro's wrists 'look' cupped (ie. measured as in extension) at the top of their backswing. Why do you want to bow your wrists anyway, apart from getting forward lean in the later downswing?
  13. I live in the UK but doesn't Erik Barzeski operate from there (ie. the local pro for 'The Sand Trap' golf forum)? https://thesandtrap.com/ https://golfevolution.com/locations/ He also has 3D Gears technology too which might interest you. ps. He's also got a background in Physics and seems to have a good knowledge of biomechanics. I've changed my mind about Erik Barzeski as he seems to teach a specific type of golf swing that might not meet your needs.
  14. The OP is probably better off seeing a local pro for guidance but I imagine his snap hooks are caused by an incredibly strong grip and the fact that he is 'running out of right arm' at/through impact. When I say running out of right arm, his right shoulder is not moving down plane enough and closer to the ball therefore his right arm/wrist will have to prematurely straighten just to get the club to the ball. When your right arm and wrist straighten, your forearm and wrist will naturally rotate and close the clubface rapidly. Trying to fix bits and pieces of his swing using people's opinions about kinematics of a golf swing might not be helpful so he's better off seeing a professional for hands-on lessons and practice drills.
  15. I agree that the majority of golfers who have no interest in biomechanics will not benefit from the charts I've shown but if the NCT is being sold based on scientific data (as is implied on the HackMotion website) do you not agree that I have a right to raise questions also using science data? Biomechanical data can be very useful , because the kinetics can provide guidance (up to a point) for feel while the 3D kinematic data can also help in identifying movements that risk of injury to the golfer. Here is a good example and it doesn't need to apply to PGA Pro players but any golfer. https://www.youtube.com/watch?v=hBFjwGzG4XA
  16. Further to my previous post here are the average graphs for 56 PGA pros Top Image :Note that there is no ulnar deviation or palmar flexion in the early downswing but some 'coupling' only later around P5.5. Bottom Image: These show virtually zero angular velocity in 'radial <->ulnar' and 'extension<->flexion' movements in the early downswing. These golfers do not seem to mirror an NCT action.
  17. Gary Woodland 3D graphs 1. Red Graph - Lead Wrist - Ulnar Deviation above zero-degree line - Radial deviation below zero-degree line 2. Green Line -Lead Wrist - Flexion above zero degree line - Extension below zero line. Consider from top of backswing and early downswing: No increased lead wrist ulnar deviation (in fact slight increase in radial deviation) while slowly moving in the palmar flexion direction (ie. wrist is still in extension). Therefore, no coupling action happening where palmar flexion and ulnar deviation happening together until much later in the downswing at about club horizontal. Therefore, no early casting action as per Monte's NTC instruction. Jamie Sadlowski - with a strong left-hand grip Small gradual lead wrist flexion in the early downswing while a slight increase in his radial deviation (no coupling). Then one gets a more rapid increase in palmar flexion direction into impact (ie. still slightly in extension at impact) with movement into increased ulnar deviation. Again, this does not appear to mirror an NTC action. John Rahm - Sorry about the quality of the graphs Lead wrist moves from being more palmar flexed at the top of his backswing to less palmar flexed in the early downswing. While the latter is occurring his lead wrist moves into increased radial deviation. Only much later in the downswing is there a coupling of increased palmar flexion and ulnar deviation. This is not representative of an NTC action. I've got some lead and trail wrist 'Flexion-Extension' graphs of Steve Elkington and Ernie Els but unfortunately not their 'Ulnar-Radial Deviation' graphs. If I find any more 3D graphs of Pro players (or ex Pro players), I'll post them here. Here's another 3D Graph of an unnamed golf pro from Dr Phil Cheetham's dissertation. In early downswing, no lead wrist ulnar deviation while a slight increase in extension (ie. no palmar flexion and ulnar deviation coupling happening). The 'coupling' happens later in the downswing around P5.5. Does not seem to represent an NTC action. Patrick Cantlay No lead wrist ulnar deviation in the early downswing while very small gradual increase in palmar flexion direction (while still in extension). Only in the mid-downswing is there a coupling of increased palmar flexion and ulnar deviation. This does not mirror an NTC action in the early downswing.
  18. I don't think the evidence is available so yes, no point debating anymore. People will just have to make up their own minds.
  19. No, I've asked where is the evidence to prove his theories. It is claimed he used HackMotion data but what are they measuring and how has it been interpreted by Monte? For example: 1. Has he got data showing that all elite golfers actively try to cast early in that 8 O'Clock direction during transition/early downswing? If it's just an active intent but doesn't end up casting how does he know they used active intent ? He wouldn't know unless he's stuck needles in the golfers muscles and done 'Electromyography' measurements. 2. Has he got data showing that golfers use the 'Reverse Motorcycle Move' and does he have proof that this action closes the clubface early, allowing the golfers to just pivot through impact limiting the need for late forearm rotation to square the clubface before impact? If he's already considered the data and thinks it will create a Pro-Caliber swing , then publish it. He doesn't have to break any Tour Pro data confidentiality just show the trends and the reasoning behind his interpretation of the data.
  20. I disagree that Monte doesn't get into the science or detailed body movements because he apparently based his instruction on HackMotion data for pro golfers (see below). He also specified directions on when to 'cast (ie. the 8 O'Clock position) and the use of active body movements like wrist ulnar deviation, not tilting shoulders, etc. ---------------------------------------------------------------------------- https://hackmotion.com/no-turn-cast-monte-scheinblum/ Coach Monte Scheinblum has developed the training concept of No Turn Cast, which he developed using HackMotion data from tour players. 2. Have the INTENT to release club (“cast”) to 8 o’clock (shaft parallel before impact) As a conscious move when starting the downswing, release wrist hinge (move towards ulnar deviation) and the body will react automatically The move should be done while shifting from the 9 o’clock to 8 o’clock position (shaft parallel before impact) and without tilting your shoulders (see the illustration). *Reasoning Ulnar deviation (unhinging) is a coupled motion with flexion (bowing). Therefore, by having ulnar deviation. in the wrist, it becomes easier for the lead wrist to move towards flexion. A move towards lead wrist flexion allows to square the clubface earlier, so that you don’t t have to do it at the last moment. You do not need to manipulate the club before impact and you can rotate freely. 3. Rotate the body Once the clubface is in a good position, you are able to gain speed by rotating the body. ---------------------------------------------------------------------------- Also, what I am saying isn't rocket science and all I've implied is that you shouldn't practice drills that promote active positive hand torque on the grip of the club. Actively using the wrists will tighten them up and will not be conducive to a fluent release of the club to optimise clubhead speed at the right time.
  21. Virtually every elite golfer has the club rotating faster than their hands can keep up approaching impact, so do you think they have major swing flaws too? The fact that your hands are stable as rock before and after impact doesn't sound like a good way to optimise clubhead speed to me and won't make any difference to how you compress the ball for the 4/10,000 sec that the clubface is in contact with the ball.
  22. To make it simpler: 1. By the time your clubhead gets a few feet before the ball, the club shaft and grip is twirling around so fast that your wrist joint movements (as per image below) cannot physically keep up. 2. Because the wrist joints cannot physically keep up, they are actually being dragged along by the club into impact. Which is equivalent to the wrists actually pulling on the club as it approaches impact (Newtons 3rd Law). When you pull on something , it also pulls on you, and in this case it's the club pulling on your hands/wrists , while your hands/wrists pull on the grip of the club. Now do you think practicing the broom force drill recreates the above conditions? The only thing it would be successful in achieving is getting the body/arms/hands in the correct impact positions (ie. forward shaft lean). The forces you would exert on the broom a few feet before impact would be the opposite of point 2 above because your 'hands/wrists' would be 'pushing/rotating' the broom rather than the broom 'pulling/rotating' the 'hands/wrists'. So, there are good points to Monte's broom drill but also drawbacks with regards mirroring the hand release action of elite golfers.
  23. You seem to make a habit of stating wild allegations about me: 1. Confrontational 2. “questioning the science” behind every coach’s drill that anyone likes or posts about 3. You are being unfair to the forum members here 4. You’re being unfair to Monte Then you make another assumption that forum members are an audience who do not care about the biomechanics/data (I'm sure there are some who do care). Anyhow if the broom force drill helps your body /arms get into the correct position I personally think it might also ingrain a non-optimal positive hand torque trait too. https://www.tutelman.com/golf/swing/golfSwingPhysics3a.php "positive wrist torque causes the club to unfold early, and therefore causes the clubhead speed to peak early, and with a lower velocity. Common symptoms include a pronounced swishing sound that peaks before impact, drop-kicked shots (club ricochets off the ground before impact), shots with a high trajectory, and often problems with big high fades or slices." "This is a very tough lesson, yet all of us have experienced the occasion when we relax, try not to hit a ball too hard, and hit the best drives of our lives. Learn to relax, to shorten your grip, and not to use your hands." "Many people have trouble believing that you do not need to use wrist torque to have an effective golf swing. But to prove a point, some stunt golfers use drivers with a section of rubber tube or dog chain replacing part of the shaft. They still hit the golf ball a long way -- in fact, much the same distance as with a proper shaft. With such a flexible shaft, there is no way that wrist torque can have any effect." Monte is an ex long drive champion so maybe he is using those feels in his own instruction: "With professional long-drive golfers, the shaft length is longer (up to 50 inches), the natural swing time is much longer, and a swing with a natural release is anatomically impossible. Professional long drivers must use positive wrist torque (forcing the club out) to complete the swing."
  24. The last time I questioned his and Tyler Ferrell's instruction on Golfwrx they banned me so there is no point approaching him. If his method works and he can prove that a certain percentage of his students have improved their performance why not publish the results (especially if they were in his favour)?
  25. As far as I am aware Daniel Burger is the only one in Jon Sinclair's 3D database that flexes his lead wrist more through impact while all the rest extend their lead wrist. What's this specific position they are talking about? Hackmotion is not a very accurate tool and operates at 100 Hz which means very few sampling points to measure wrist movements (especially approaching impact). 3D systems that were used by Jon Sinclair operate at around 400-450 Hz (still not quick enough imho).
