Forearm Rotation in the Golf Swing - The Key to Staying "On Plane"

[@geetar21]

Best description of forearm rotation and timing that I've ever seen. Thank you so much for the clear explanation. The Hackmotion data comparing to Tiger's swing gives added credibilty.

[@ZachAllenGolf]

Glad it was helpful!

[@gordonlove7717]

Zach is a brilliant teacher.

[@Chris_Traynor]

That was a truly brilliant explanation of this part of the swing which I struggle with. I play mid-singles in Scottish weather with a slight reverse of this (i.e. early forearm roll to slightly steep) and though it is visually a very minimal amount it really causes me difficulties where I am 'on the edge' sometimes doing it correctly and sometimes wrongly. I think your explanation may just be what I need to move more consistently towards one of those ways.

[@75tram]

Great video as always - would be really useful to see how the forearm rotation works on the downswing through impact

[@ZachAllenGolf]

Noted! Will look into it.

[@mizal7893]

​@ZachAllenGolf I agree. A downswing explanation of the forearms would be great.

[@mntlblok]

@@ZachAllenGolf While you're at it, might you also address how trail arm external rotation during this period seems to be the opposite rotation (spin?) to trail arm pronation? Kinda has me flummoxed. Apparently related to the trail elbow needing to be close to the torso. . .

[@frankobrien8734]

Eureka! A natural and easy solution to Over The Top. Thank you Zach and Mr. Hogan. The most important video for my swing improvement I have ever watched.😊

[@richardc4814]

Thanks Zach!

[@rondriggers2755]

Very well explained. Thank you

[@pigslefats]

Very good video. Thank you. 4:01 "The golden piece. I start to very quickly switch my forearms and continue that into transition" Never seen this covered in the hundreds of youtube golf lesson videos I have watched. Lessons tend to focus on hands by right thigh and then shaft plane half way back and then to the top and the rest. Never how quickly the forearms switch. I'm always scared to do that lest I come too much inside. Have more confidence that I can do this quickly now. Zach, anything I have to guard against plane wise after one piece to thigh? Should it fall into place or can it still get too flat?

[@ZachAllenGolf]

Great question glad you enjoyed the video. So the next switch occurs at about 1/2 way down in the down swing. I call it the tumble. This keeps the shaft from getting to flat or stuck behind you.

[@VoodooZ]

Amazing Video! that basically covers most of my struggles.. I can literally see my trail elbow getting "stuck" behind me in transition. I've been able to get that feel of shallowing this year but I can't seem to get the right takeaway move so I'll try this as It looks very simple compared to my super handsy one. Thanks!

[@BHJ7115]

Awesome insight on what's been a hurdle for me to overcome. Thank you Zach!

[@josephcoble9681]

Excellent ! About time.

[@annetorunnogegilolsen287]

Hi, the best KZbin video ever (for me) how have strugle with to closed and to open Club face in many years. For me it worked perfect on the range and on the course immediately. More practice and I think it will be even better. Thanks Zach, regards from Norway🏌️‍♂️😁🇳🇴

[@ZachAllenGolf]

Glad it helped!

[@asiangolftravel]

Thanks for great tip

[@ZachAllenGolf]

You bet!

[@carstenbahnson1848]

Great video Zach!

[@ZachAllenGolf]

Thanks glad it helped.

The forearms do not rotate. All rotation in a good golfswing is around the upper arm and occurs at the shoulder joint. If you rotate the forearms at the elbows,the club face is rotated wide open, and the club is slung around below plane requiring a subsequent lifting of the arms,and a loss of rhythm. The simplest way to get rotation right both ways comes from Homer Kelly's"The Golfing Machine. It is called extensor action.You gently pull on the grip as you start back. Like pulling on both ends of a rope. The right armto move behind you,and will start to rotate with the left arm acting as a checkrein. At the top,the right arm will be bent a perfect 45 degrees and rotated. The left arm will be straight but not rigid. It is an effortless move that has allowed me to keep playing at age 81 in spite of significant disabilities.

Great video mate

[@crownator]

At the beginning, you mentioned on the backswing we should make a steering wheel “right turn“ with the forearms and and a “left turn“ on the downswing, but it almost seems the opposite since on the downswing your right arm goes below, the left, which is more of a right turn motion. Or am I missing something?

[@ZachAllenGolf]

Yes you want to delay any forearm rotation until you hit your trail leg in the takeaway, the forearms will then rotate as you change direction. The timing of when you rotate your forearms is so crucial. We all will rotate are forearms but when and for how long is the key to mastery.

[@rossmasters3281]

Should the forearms and upper arms be independent motions? I notice at 4:40 your entire arm rotates instead of just the forearm. I can hardly understand why people are specifying the forearms if the entire arm doesn't rotate together. Thanks!

[@paulwhite6367]

welp......i've needed this video for the past 20yrs lol

[@mikeshevlin]

Great Video Zach. Can you send us the link or the name of that Dual putting grip aid? Thanks again.

[@ZachAllenGolf]

It’s really old. Made originally by Medicus

[@580WorldDiamondTower]

Where can I get the club attachment you used. Thanks

[@ComoGolfFoundation]

Medicus putter training aid

[@ZachAllenGolf]

Got it on eBay it’s made by medicus, but for putting.

[@jessecooper9795]

​@ComoGolfFoundation a tennis racquet works just as good

[@seel311]

Can you make a similar video covering the wrist rotation through the ball and follow through?? I think I do fairly well with my back swing but I have noticed I have low point control issues, and when I watch videos of myself my arms are slightly bent or feel "stuck" in the down swing. I think I am not completing the rotation through the swing and creating the space for my fore arms to turn over as I hit the ball. I think this also causes me to lose some distance as I don't generate the "whip" that I could with my wrists. Curious if this is a related problem and what the proper timing of the wrist rotation looks like in the down swing swing with this model.

[@mattcostello655]

Great video Zach. Cleaned up my "on plane" backswing which was done by pivoting around the right elbow too much too soon. Is it fair to say the switching happens around the same space relative to the ball in the back and the downswing? In the backswing its right around right thigh, downswing it feels like the club wants to release from that same spot and have the forearms switch back into the other direction. Switch at the right thigh (for a RH golfer) is a nice on course swing feel. Also as you switch in the backswing is that the time to start to add pressure into the lead foot and push the pelvis away from the ball?

[@phananthony1362]

Hi Zach, can this shallowing move still works with a slight pause at the top of the backswing?

[@ZachAllenGolf]

It can but would be slightly more difficult. The club loses its dynamics and momentum.

[@williamreichert4798]

You. might want to include what. your hands are doing(flexing on the backswing and extending after impact) during the arm rotation moves

[@dennisfrench2874]

Send 3 part series please

[@mntlblok]

Whoa! Does Rahm bend his left elbow a bit during transition?? Looks like a little "lag and snap" possibly going on there!

[@ZachAllenGolf]

Definitely some slingshot happening.

[@Jackybug]

‘Turn your body and stay in place’, is that on the back swing or downswing?

[@comicus6769]

Great drill, believe it or not just on my own I used to swing that way on the course (without any knowledge about the drill or forearm rotation) some 30 years ago. It got me from about a 22 to a 14 and then later on didn't need the stop at the 1/2 way point.

[@EfrenNg-jz9kh]

how quickly the forearms switch

[@bettyhughes2084]

The problem is contrary to what you say Woods’s graph seems to show constant steady rotation during the entire backswing. He really does not seem quickly to switch his forearms. In that drill it looks like Rahm has his arms rotated as well.

[@jackflash8756]

HackMotion doesn't measure independent forearm rotation, it measures 'global rotation'. Unfortunately the forearms do not rotate with each other in the golf downswing (see Jon Sinclair AMM3D graphs). They actually supinate together in the downswing , but just before impact (maybe P6.5 or a little later) the trail forearm moves to slightly less supination (ie. in the pronation direction).

[@mntlblok]

That is *very* interesting. Sounds like it fits in with my current exploration of trail arm pronation and trail arm external shoulder rotation. Maybe they're *not* moving in opposite directions "coming down". . .

[@mntlblok]

First video I find of Sinclair he soon credits Dr. Rob Neal. Instant credibility.

[@rondriggers2755]

Test

[@jonathanquinn4236]

This was good until the nonsense at the end

[@lawrencesargent1392]

The problem isn't the videos that you are studying, it's your understanding of the laws that govern this universe. You need to understand the physics of rotation and the geometry of the circle for starters. Law of the flail, of the triangle etc. You can talk about arm rotation all you want but if you don't have a flat left wrist at impact nothing will work. The understanding and the information you are seeking is contained in THE GOLFING MACHINE BY HOMER KELLEY.
