Myth of Maintaining Your Address Flex in the Rear Knee


Recommended Posts

Posted

This worked for me during my last round. Stopped hitting it fat. My follow through was all over the place though (felt kinda funny implementing the knee flex), but the ball went straight, got a lot more GIRs and I played to my handicap for the round.

Such a simple fix. Will hafta work on the follow through but so far so good. Thanks again!

Great to hear!  The "implementing the knee flex" are you referring to regaining flex on the downswing?  Not something you have to think about, happens pretty automatically.

Yup correct, 'regaining flex on the downswing' is what I was referring to, I suppose it did happen automatically...and contact was solid as ever, but during the follow through, I found my entire body lifting up and all the weight ended up on my back foot. Not at every iron shot, but maybe 60% of the time. I should probably get a video up to explain it better.

I guess now it's a small matter of fine-tuning the weight-shift after impact. But the great thing is that my swing path HAS been corrected, and the shots are getting more accurate.

Part of the S&T pattern is for the trail knee to lose flex and the left to gain flex on the backswing.  But like I said no S&T golfers have been featured in the thread or video

This is a great thread, I think this is going to change my swing for the better. As with many things in golf, I really wish I had found this site sooner.

I think this will cure my head tipping forward and dipping down in my backswing which I've been fighting for a while, even when I tell myself to keep it still. I had been trying to maintain way too much flex in the right knee in the backswing. I think this will also increase my shoulder turn. Excited to try it out.

mvmac, your son's swing is real impressive! I'm excited to dig deeper into this site, I like what I'm reading.

Last night I had a lesson with a really good young teacher and he told me my problem was that I straigtend my back leg and that was what was messing me up, he took a picture of me at the top of my swing and I'll post it when I get home. So I tried to prevent keep the back leg from straitening and it fixed my driver swiing a bit but then it just put everything else off kilter. He also said I shoudl quiet my lowe body. Thoughts? Advice? Thanks.

It's going to be tough to say without anything more than that, but the trail leg should decrease flex throughout the backswing to allow the trail hip to rotate back and up. Same is true of every club, and more important with the driver. Bubba Watson's hip turn is huge, and his knee straightens quite a bit.

The move , which I am sure has been mentioned in this thread is that the right leg "straightens" ....not "stiffens"

There still is some flex left in the right leg before pressure is exerted on the right foot....then, in my opinion the right foot banks as the knee regains some flex and then the right leg straightens as the hips slide and turn....

I'd love to hear peoples' thoughts/feelings regarding the re-flexion of the rear knee at the start of the downswing. I tend to straighten the rear leg a fair amount (as I should) but then at the top for some reason I give the leg an extra 'kick' straight and it seems to pretty much remain straight for the majority of the downswing, only re-flexing toward impact.

Need to figure out a way to prompt myself into re-flexing it I believe.

I'd love to be able to keep my rear leg straight more on the downswing.  I'd like to see a picture or video of you to see just how straight it is.  Be careful of trying to flex it too much on the downswing or your upper center will tip back and you could hit fat shots.

The short answer? It regains address flexion around A6, then extends from there. It shouldn't ever cross through "the wall" established at A1.

Swing looks really good btw. Not to get too far off topic but here's what I see, using Hunter Mahan

Looks good to me, could even turn the right hip a little deeper

I've gotten into this a little on this thread and on another thread about flaring the feet in the set-up.  Important to not only flare the feet (turn them out) but also have the knees turned out as well.  I'll re-post that info here about how the body works and how it makes sense to turn the feet out, especially the rear foot, rather than perpendicular to the stance line.

A1 Alignment Comparison.jpg

The hip is a ball and socket joint. The thigh bone (femur) ends with a rounded projection or ball (femoral head), which fits into the socket (acetabulum) of the pelvic girdle.



hip-flexors-anatomy.gif

The hips go from flexion to extension.  Flexion of the hip occurs when the angle between the torso and thigh is decreased. When this angle is increased extension occurs.  Ok so what does all that mean?  We play golf on an inclined plane and to get the hips to accomodate for that, the trail knee has to lose, release flexion.  Check out Rory and Sam Snead, their trail hips are higher than the left at the top of their back swings, it will be the opposite on the followthrough.  Flaring the feet our helps the trail knee lose flexion.

The toothpicks and clay was an example Dana Dahlquist gave me (below)  If we try to turn the hips level, staying in address flexion, that's when we're working against how our bodies we designed to move.

You wouldn't believe how much this tip has helped my irons in the past week.  I always felt like I was trying to fight my legs and hips in the backswing, because I was always taught to keep the knees flexed.  By allowing my right leg to extend on the backswing, it not only feels more natural, it has allowed me (as a guy with serious back problems) to not feel as much discomfort in my back and hips after a round of golf.

    • Day 610 - 2026-06-03 Got some work in between lessons today. Rare late day, teaching until 7:30pm.
    • Let's continue on… Cool. The thing is, nobody's claiming par is "reliable" and par's inclusion piggy-backs in the course rating, which is awfully close to par and, thus, brings par in to make it make sense. Once again, for those in the back… (CR - Par) just makes it really easy to know what kind of score you need to shoot to best, match, or play worse than your handicap index. Yes, when par is different, the players from the higher par tees get an extra stroke (72 vs. 71, the 72s get an extra stroke. That makes sense and is a small complication (more info at https://www.usga.org/content/usga/home-page/handicapping/roh/Content/rules/Committee%20Content/USGA/LG_R6d.htm). However, most of the time, this adjustment will not be needed, as many courses play to the same par for the same genders from all sets of tees. And, the rare times it is needed, par (measured in whole numbers, integers) and strokes (also whole numbers/integers) map easily and the idea is easily grasped. Dean seems to be unaware of the fact that most every golfer carries something orders of magnitude more powerful than the highest end desktop computers available the last time he consulted with the USGA in their pockets. While it is quaint that his club puts printouts by the first tee… get with the times, Dean. Look up your handicap index and course handicap in the GHIN app and get on with it. It's a better system than the one that didn't account — at all — for a difference in the playing conditions (via an algorithm, not a judgment). Dean's assertions about the "less precise system because of par" continues to make absolutely zero sense. Right, it still changed tee to tee. Now it just changes differently… and in a way that more accurately reflects the score you need to shoot to play to your handicap. Previously, a 1.1 index would get 1 stroke on a 66.7/122 par-72 course. Now they give four strokes back to the course and must shoot 68 to play to their handicap. This makes way more sense. The 18-shot difference is a pretty extreme example. Maybe a long course that also offers a par-three set of tees could play that long, but… man, that's not going to be super common. Sensationalistic much, Dean? Also, once those unhappy (complete assumption) golfers realize a) what the change shows them (playing to net par = playing to your index) and b) realizes that their differential is going to be the same… I think they'll get over their initial questions. No. And yet… if he shoots the same scores, he'll get the same handicap index he has now. But he'll know on each course what score he needs to shoot to "play to his handicap." Sheesh, Dean. This stuff isn't that hard to figure out. Enough with the sensationalistic stuff. I don't find it "unacceptable" at all. Then again, I'm not nearly 80 and seemingly incapable of doing basic math these days. No. This literally makes no sense, as that part of the differential calculation and the course handicap calculation remains identical. Good! No. Categorically wrong. They should have been adjusting their handicaps all along. Previously it was by subtracting the course ratings. Which… is still basically what's done, with the addition of the course rating being "baked in" to the course handicap calculation. Dean is wrong here, or doing some math heretofore unknown by the world. When par is the same, what determines the difference in handicaps? The course rating, which Dean loves! Sheesh! You had to things when players were in situations like this before, too. This is getting exhausting. He keeps using words like "less precise" and "unfair" but does not seem to understand what they mean. This is like the Princess Bride meme: "you keep using that word. I do not think it means what you think it means." The caps reduce upward movement. Committees have reign to reduce a player's handicap, and there's still an automatic Exceptional Score Reduction. I'm going through these more quickly now because… well, it's silly how badly Dean misses the mark with this blog post. Dean is literally confusing the upward movement (with the soft and hard caps) here with the exceptional score reduction which is used when lowering handicaps due to an exceptionally good score. The creators of the WHS are handicap experts. They know more about the current state of handicaps/handicapping than the Pope Emeritus. It's been shown to have almost no effect across all handicaps. Yes, some 36s under the old system are now 35s under the new system. Yawn. He should have stopped there. It's easier to apply and makes more sense. This makes no sense. It's "not complex" but players will have to guess? And, for men or women, the stroke index of each hole doesn't change because they play a different set of tees. They get a different number of strokes, but it's always been true that when you get 14 strokes you apply a stroke to stroke index holes 1-14, and when you get 11, to just holes with a SI of 1-11. Objection, your honor. Assumes facts not in evidence. Dean's just out here continuing to make shit up about "the inaccuracy of par" and ignoring that with Par (an integer) came the Course Rating, which he agrees is precise and accurate. No. No, this is inaccurate. Also, as noted, you can randomly assign stroke indexes, and so long as all the low numbers or all the high numbers are not clumped together at the beginning or ends of the 18 holes, matches generally work out the same. This is inaccurate. It is an algorithm that looks at scores. That's it. Also, this is better than a system like the prior one where no such thing existed at all. Wildly inaccurate and off-base. Did they do actual testing? No need. They have millions and millions of rounds and ran many, many, many simulations. That's testing. Dean seems to continue to be unaware of the fact that computers are more powerful now than they were in 2002. But, he's nearly 80, so we can understand if not going so far as to give him a pass on how much he gets wrong. Cool. Noted. For the most part that was because many countries haven't been able to rate enough of their courses. :sigh:
    • Day 3 (3 Jun 26) - More work on keeping arms connected today - hard foam balls with 7i and 5w…..
    • Day 274 6-3 flow drill getting chest through, arms in front. Arms get a little pinned to the side, not as much in front as I want them when I add speed. 
    • Shot 48 yesterday.  For me bogey golf is good.  I was 10 over through 7 and figured with a Par 3 and 4 coming on all I needed was birdie / par to get my 45. I had a great tee shot on #8 and sunk  a 5 footer for birdie, game was coming together, now just needed par on #9. Had a great tee drive and the green was within range for a hoped GIR or nGIR.  But I pulled the shot left into tall weeds and needed to take a drop.  So much for par, but a bogey for 46 is still good for me. I hit my lob wedge to get over a small tree and saw the ball riding nicely  on line to the pin when my club hit the ball a 2nd time on my follow through causing the ball to change directions and ended up @ pin high but along the same tall weeds I just took an unplayable out of.  had no room for a backswing, Just hacked at it and it shot across the green to the rough on the far side.  Needed a chip & 1 putt got a triple bogey. you can see the hole fall apart in the screenshot below.
