I know there are plenty of threads about stopping the dreaded flip at impact so I hope it's OK to start another one. I read though a thread on another site regarding Jim Waldron's arm swing illusion. While the thread was mainly focused on the arm motion in the back swing (which I thought was excellent), there were some tidbits about flipping the wrists at impact and it being caused by the hit impulse. I'd like for this thread to be focused on that.
What I believe he is saying is side to side arm motion vs. up and down arm motion is what causes golfers to flip at impact. He believes that side to side arm motion is caused by a hit impulse. Hitting at the ball vs. swinging through the ball. He goes on to say that to fix the hit impulse you have to see through the arm swing illusion, and clearly define wrist hinge and wrist cock. In general, hinge is primarily done with the right wrist, and cock is primarily done with the left wrist in a right handed swing. Both elements occur in both wrists, however these elements are more pronounced in one vs. the other.
I know that arm motion is important, but I'd like to focus on wrist action once the hands get to waist height in the downswing. What really stood out to me was his explanation of what should happen at this point in the swing. Lets assume that a golfer can reach this position correctly with the arms and wrists (left wrist up-cocked, right wrist backward hinged). All the golfer needs to do at this point is down-cock the wrists and maintain the right wrist backward hinge while turning through the hitting zone. He says that if the golfer reached this position and did not turn through the hitting zone, the aiming point for the club head would be on the ground along the toe line. He says that all of this is compromised if there is any lateral arm movement, and that lateral arm movement should only occur well after the ball is struck.
This made a lot of sense to me because you're not forcing a wrist position, you're setting up a wrist position once you get to the top, and then maintaining it (with the exception of the down-cock).
There is a strong timing element in this (many aspects of the golf swing are), but he says that the low point can be manipulated by grip strength. Thin contact, very slightly increase grip pressure, fat contact, very slightly decrease grip pressure.
I've had a flipping issue with my swing for quite some time, so armed with this information I gave it a shot. In previous swing videos I'd be lucky to get to 1* forward shaft lean at impact, and after impact my LEFT wrist would be hinged backwards. In current swing videos I'm getting about 4 to 5* of forward shaft lean at impact and I'm maintaining the right wrist hinge for approximately 6" after impact. I went from slight fade to slight draw, and it's working for every club in my bag. I've had about 5 or 6 range sessions since discovering this, and while it needs to be honed, it has held up better than I could have imagined.
I'm curious if anyone else has seen this, tried it, and had success (or no success). Also curious if this makes sense to any of the instructors.
