The 84 Degree Secret
The manner in which the body works through the swing is integral to achieving a proper and productive impact position. In fact, body motion is the prime fundamental for striking a golf ball correctly. By pivoting and loading the body correctly in the backswing, you set off a chain reaction that automatically directs your body to where it should be at the moment of truth: impact!
Let’s start with the prime objective: To have your body weight 80% or more forward at impact while delivering a downward blow (at least with the irons and fairway woods) with your head over the ball.
In researching the great golfers, it quickly became apparent to me that there was something eerily similar about the manner in which they all pivoted or rotated their bodies to the top of the backswing. Their arms and clubs, however, were doing quite different things. I drew a straight line up the outside of each player’s back side. This way, when each player approached the top of their backswing, I could focus purely on their body movement.
The result was uncanny. Not only were the majority of the back side lines I drew at exactly 84 degrees – almost every player stayed not only inside that line, but flush up against it just prior to initiating the downswing. They were flush up against the 84 degree line prior to any part of the body initiating the downswing.
A few interesting points:
- In the past I taught golfers to get the weight into the back foot in the backswing. The 84 degree line does not advocate a reverse pivot, or moving the weight to the target in the backswing; it merely encourages keeping the weight centered throughout the wind up.
- I do believe the 84 degree line to be vitally important to any player’s game, because it keeps the body from straying too far from its final destination – impact.
- The more the body moves away from the target in the backswing the greater the distance it must travel in the downswing to get the weight onto the front foot.
- The 84 degree line also allows a player enough space to develop the necessary power for the shot without driving too far forward and in front of the ball.
The 84 Degree Secret is applicable only to iron swings. The reason for this is, as the stance gets wider, the line remains at 84 degrees, but that line gets pushed further from the golfers’ center, making it very difficult to get the full back side to press up against it.
With my new understanding that the golf swing is — or should be – all about impact, I now see that getting the body into proper position at address and at the top of the swing allows it to then glide down into a sound hitting position.
Set that chain reaction and allow the rest to happen.

Thanks for reading and I would love to hear your thoughts on the 84 Degree Secret.




Historically speaking, it seems that whenever somebody says or writes anything about a particular topic their statements are held as law or truth. Many of these statements go unchecked by anybody. Many years ago, there was a common belief that the earth was flat. Anyone who spoke out against this belief was bannished from society. That is until someone actually proved that the earth was round. It took a great deal of convincing, but after a while everyone came to beleive that the earth is in fact round. Unfortunately, in golf there are many things that are being published that are just flat out wrong yet held as common truth in there respective circles. I have studied many golf swings in great detail and I can say with total confidence that the 84 degree rule is in fact an absolute truth. When I first heard of the 84 degree rule the first thing that I did was check this theory for myself. Sure enough, every professional that I checked obeyed the 84 degree rule with an iron. I would now classify it as a fundamental of golf. I also studied many swings that were, shall we say, not of professional caliber. Many of the player’s that I looked at who had impact problems violated the 84 degree rule. They tended to hit shots that were fat and thin and in general had poor pivoting motions through impact. Coincidence? No chance!!! The 84 degree rule is as real as the earth is round. Great work Andrew!!!
Wow! Thank you so much Brian. I have never received such a vote of confidence from a fellow golf instructor. Your input here is very much appreciated.

I think that people who are good at golf either started young, have natural talent, hit tons of balls, or some combination of the three. However, for the rest of us there is a steep learning curve to good ball striking. You know why I know this is a good fundamental? Because this is EXACTLY what Bobby Jones did in his swing. Take a look at any of his films and you will see the 84 degree angle at work. I have found that if I stay centered and perform the correct backshift pivot, basically imitating Bobby Jones without the high left foot, I hit it well. Have you ever heard of Mike Maves? He goes by the handle of Sevam1 and is a guru on the subject of backshift pivots and using the ground correctly. I think you guys would have a lot to talk about.
Hi J.D.,
Thanks for your input. I 100% agree with you, yet many, many “style” instructors would not say that Bobby Jones had the correct backswing. It is less about where the club goes and more about what the body does. (Although, where the body goes often dictates where the club goes….) Almost every one of the greatest golfers obeys the 84 degree line! I firmly believe that it must be a factor in their success.
I do not know Mike, but I’ll try to look him up.
Keep reading and learning.
Cheers,
Andrew
hi andrew:great article on the 84 degree rule,& the drill.it has helped my game tremendousley.by the way you have a great dad & he is a terrific golfer.i have played several rounds with bill at sage meadows golf course.thanks again for the tips.jd.
Andrew,really enjoyed reading about the 84 degree line very interesting.As a fellow PGA professional I only wish gentlemen like yourself would help educate other instructors who would look at this and say your weight must move across more to the right side.I love reading articles like yours as I often feel I’m alone in my views of teaching. Keep up the great my friend.
