Want to know how to hit the ball 300 yards with a swing speed slower than any on tour? Read on.

I have always had a pathetic amount of swing speed. As a junior, all the other kids much younger than me used to whack it 40 yards past me. One of the deciding factors on whether I pursued a career playing professionally or go into teaching happened when I played the Welsh amateur. I got beat 6 down with 5 to play. He hit the ball 70 yards past me (230 to 300), and was going in with wedges to par fours I was struggling to reach.

Please, shed a tear for me.

In the test I describe here, my clubhead speed only averages 102.5 max, which would be dead last on tour.

My highest average clubhead speed of 102.5 would be dead last on tour.

By a whole 1 mph 🙁

Comparing it to the fastest swingers on tour makes me feel even worse

## But, there is hope

## +5 AOA

I decided to start with a +5 AOA, as this would typically be my norm for me. After 10 shots, here were my results.

As you can see, my average clubhead speed was 100.9 mph. My average Angle of attack was 5.8 degrees upwards. This produced an average distance of 288.6 yards, with a top distance of 295.1 yards. Carry distance was at 262.4 yards in the air.

## Neutral AOA

Next, I tried to level out my swing. This would be the typical average AOA on tour for men. See the yellow group

As you can see, the YELLOW drives averaged and AOA of -0.7 degrees. Average total distance dropped down to 273, with the highest distance being 278.4 yards. Carry distance dropped down to 234.4 yards.

## Negative AOA

It is very common for us as teachers to see average players with very negative angles of attack. This means the player is hitting down drastically on the ball. It is not uncommon for me to come across someone hitting 8 degrees down with a driver. Well, let’s look what happened when I did the same.

Now, the purple numbers represent the negative AOA. On average, it was a 5.2 degree downward blow. This is actually very common amongst amateurs. The distance achieved with the same swing speed now dropped down to 257.7 yards, with a longest drive of 266.7 yards. Carry distance dropped off significantly, averaging only 216.5 yards.

## Positives and negatives

So, going from a -5.2 AOA to a +5.8 AOA resulted in an extra 31.9 yards total,and an extra 46.4 yards carry distance. This was with the same swing speed of 101 mph. There are some problems which I will address in a moment, but first, let’s get EXTREME.

I decided to have a look at how far the ball would go if I hit as much up on it as possible. I went beyond the limits of most people, into the ranges of long drive champions to see how far you can get with maximum efficiency of a powder-puff swing speed. Below are my results.

Now I have gone to a crazy 8.1 degree positive AOA. That is a full 13.6 degrees difference in angle of attack. In fact, if you look, you will see one AOA of +11.4. While it is certainly not realistic to make this kind of change to a player overnight, understand that I did this in a matter of seconds, from one swing to the next.

With this silly amount of positive AOA, I managed to get an average total distance of 295.5 yards, a maximum distance of 305.1 yards, and a carry distance of 272.4 average. This was with a slightly higher clubhead speed (1mph) and a resultant higher ball speed. But I seemed to find it easier to create this higher speed without any extra effort. I theorise that the positions I was using to create the positive AOA also helped me use the ground better.

This means that my total driving distance was improved by 37.8 yards, my carry distance was improved by 55.9 yards.

## The results in table form

Below are the results in a table for visual ease

## Adjustment of results

Let’s assume that the driver is well fit to the golfer. (That means that launch angle and spin rate are proper for the golfer’s clubhead speed, AoA, wrist cup or bow, etc.) Another assumption is central enough face contact to get a smash factor close to 1.5. Under those conditions:

*** You get about 2 additional yards for every additional MPH of ball speed.”

## Efficiency

What about the physical ball flight efficiency? What did the different AOA’s do on yards/mph of ball speed?

So, even when we look simply at the ball distance per mph, we still see a positive correlation between increasing AOA and increased yard per mph. This takes smash factor and clubhead speed out of the equation.

## Discussion and take home notes

In this N=1 experiment, increasing AOA had a positive effect on both total distance and Carry distance. It had a more beneficial effect on carry distance, offering a whopping 55.9 yards extra carry. This is positive news for a lot of people, as it offers hope that we can make massive strides in our distance even if we don’t hit the gym every day for a year. The swing changes took me less than one swing to make.But, if I am honest, it took around a year before I went from comfortably around -3 to being comfortable around +5.

It is worth noting that I used a Callaway 8.5 degree head with a stiff shaft. It is likely that, with the steeper AOA’s, a more lofted head would have performed better, especially regarding carry distance. Although, it is also worth noting that the most negative AOA also had the highest spin rates overall.

So, why did this positive AOA go further? Well, the launch angle increased dramatically. With the +5 AOA, launch angle was 14 degrees. With the -5 AOA, launch angle was around 8 degrees. Sure, we could increase the loft on the club to launch it higher, but that would also increase spin-loft and cause a drop in ball speed and increase in spin rate. I think, in order to further maximise distance, using the higher AOA and using a club with less loft would do the trick, as it would spin even less. My furthest shots with the +8 AOA were also the lowest spinning shots.

## What about accuracy?

There is also the question of accuracy. I am not lying when I say that I actually performed better with the +5 AOA, and second straightest with the +8 AOA. The more negative the AOA, the worse I performed in both distance and accuracy. Although, it has to be said that I practice more often with a +5 AOAand least often with a -5 AOA.

Everyone may be different, and some may perform better with a more negative AOA. not only does what you have ingrained matter, but how your body is mobile to move will also make a difference. The technique I used to create the +8 AOA wont even be possible for many. While there are many ways to create this positive attack angle, I feel that my way is best for me personally.

Adam:

Love your articles. I work at FINCA Cortesin where Eduardo use to work some years ago.

I am part from the pga of Spain and I would love to have you in one of our courses.

One question, with that + 5 aoa what was your ball height and would you use that aoa in strong against winds.

Regards and thanks for making all that interesting articles. I will buy your book today.

Best regards

Ricardo

Any thoughts on shaft flex point? I went to a high flex point shaft and 12deg loft . on my driver, getting another 25 yds and more accuracy. I have a high ball flight? Club speed <95/hr

## Gibson

Great info there, I wonder if it would be possible to do same testing with 15 to 20 handicap golfer. Reason, whilst your swing speed may be slower than most tour pros it is still quite a bit quicker than your average golfer and with your 150 smash factor you are also much more efficient than your average golfer. Just wondering if your average Joe would benefit to the same extent. I am not suggesting they would not benefit, I just think it would be an interesting experiment.

Hi Gibson – I did another blog post that would be of interest to you. This one – https://www.adamyounggolf.com/much-distance-losing-driver/ – explores how much distance the average golfer is losing, based on optimizing the launch numbers in the same way as this article, and for various swing speed.
