The evolution of Bryson DeChambeau’s golf swing has been fascinating to watch over the past couple of seasons.

In two years, the 28-year-old has gone from T34 in driving distance to the longest hitter in the game, and while on a recent night range session, he appears to have found a formula to hit it even farther and straighter.

In a video posted to his YouTube channel, Bryson is hitting balls alongside Long Drive Pro Martin Borgmeier when DeChambeau had a breakthrough that both men agreed was a ‘Eureka’ moment for the Californian.

After piping a drive dead center early in the session, Bryson excitedly exclaimed, “Oh my god, I’ve finally figured something out”, before going into detail, saying:

“So, when I try to apply force internally, it gets the handle there (in front of body, clubface open)…that’s right. But if I can feel like my wrist is behind my elbow as I’m swinging, it keeps the head more ahead of me.

It needs to stop (forearm/wrist) so that the handle can go forward and keep turning through. Whereas, if I keep applying force, it’s going to keep the wrist going that way (central) and keep the face open.”

After figuring out this ‘Eureka’ moment, Bryson then implored amateur golfers to try different things as “if you don’t hit the golf ball good with a thought process in the first two, three shots, it’s not working.”

Going back to his new swing discovery, Bryson says

“What I’ve found was, when this right forearm goes internal, there’s obviously weight and inertia over here (clubface), and when I apply force, that’s going to make the clubface go open. If I’m strong enough, obviously, I’m going to do that (flip forearm/hands), but then the face to path is way closed. 

So I want to feel like I’m stopping and allowing the hands to go through so I can create this in and out path, and it’s helping to initially close the face.”

With Martin Borgmeier, the two agree that the new swing move helps both path and face but were both fascinated to see how it could eventually affect the speed aspect too.

Between each other, the two big-hitters also agreed that speed would slow down until Bryson began timing it correctly but that it could actually end up adding speed. And that’s exactly what happened. 

After hitting several more shots perfectly with a little draw, Bryson noted how “it’s a way to stabilize everything and control the timing of the closure rate”. The next aspect? Adding speed.

After stabilizing his swing with the new discovery, Bryson ramped up the speed while still hammering each shot down the middle.

Within 15 minutes, Bryson was hitting his 8-iron with a slight draw and reached 163mph ball speed. Something he had never achieved before.

The Californian finished up his session saying: 

“Had a Eureka moment. Figured out something in regards to biomechanics and physics of the swing just in regards to this right forearm’s internal rotation, how it applies force to the club, how that translates into the momentum of the clubhead squaring up or not squaring up. Long story short, I got something unique and cool.”

How impressed was Long Drive Pro Borgmeier with not just the discovery but how Bryson used it to gain speed in such a short space of time? Very. He said:

“Doing that in 15 minutes and how he progressed through it, that was very impressive. I don’t think I’ve ever seen anything like this. One of the most impressive things I’ve seen this year.”
