The Spin Axis Podcast

Continuing our interview with Brian Manzella, we continue to talk about the past and future of golf instruction. We question whether PGA Tour players will simply (and quickly) adjust and regain lost yardage after ball rollback. We discuss the growing availability of practical instruction data and how AI may soon enable golfers to get great swing information from a box. Brian observes how younger instructors bypass tradition in favor of outcomes and talks about individual preferences versus method-based teaching. And yes, we spend some time talking about what we call the “extreme right-side bend swings” that are somewhat popular among the game’s younger players (spoiler: we’re not big fans).

We’re joined by Brian Manzella, a perennial Golf Digest Top 50 and Golf Magazine Top 100 instructor, with over 40 years of teaching experience and a reputation for blending science with swing artistry. In part one of our two-part conversation, we take a look back at how golf instruction has evolved. We discuss how swings shrank in the early 2000s before stretching out again when distance became a more obvious advantage, the shifting strength of grips, the Johnny Miller reverse-C finish, and the ramifications of the ball rollback. We explore why today’s players need to become world class at more than just one of golf’s skills to succeed in the modern game.

This week we were joined by Lou Stagner, the golf data evangelist and Data Insights Lead for Arccos Golf and one of the game’s best-known voices on golf analytics. Lou has built a huge following for his ability to make data both accessible and practical for everyday golfers (even though many STILL won’t believe the stats), both through his Twitter/X account or his weekly newsletter.

We dug into two of his most popular topics from the newsletter. First, from Issue 109, Lou walked us through the massive impact of being short-sided versus long-sided around the green, showing how shot outcomes and scoring change dramatically depending on where you miss. Then, from Issue 21, we examined the myth that more distance makes golfers less accurate. Lou shared the numbers on penalty shot percentage, fairways hit, recovery rates, and offline dispersion—and why strokes gained almost always improves for players who add distance.

Whether you’re an analytics junkie or just want to shoot lower scores, Lou’s insights are a must-hear.

We dive into why distance control is the single most important skill in putting, why so many golfers struggle with it, and how to do it. All too often we see golfers take the putter back too slowly, run out of time, and then “hit” at the ball to make up for it, wrecking both speed and face control. We discuss why the old advice to “accelerate through the ball” can do more harm than good, how tempo tools like a simple metronome reveal the truth about stroke rhythm, and practical drills for training consistent speed and stroke length. For more background, see the long-running discussion on The Sand Trap.

We break down what truly changes (and what doesn’t) when you switch from irons to the driver or vice versa. We agree that the differences are smaller than most think: setup leads the way (including a bit more axis tilt, often under six degrees, with the driver), while contact goals shift (no ground contact needed on a tee ball). We explore how gear effect influences misses with the larger head, why tighter spin loft matters, and how lower spin can send shots farther offline. You’ll also hear how minor adjustments to sway and path help keep your favorite feels intact across both clubs.

We’re joined by Nick, a long-time plus-handicap golfer, former instructor, and veteran fitter for one of the biggest names in golf, to pull back the curtain on the club fitting world. Nick shares his background, the types of golfers he sees most often, and the common flaws in both swings and equipment that show up during fittings. We discuss whether players should get fit while taking lessons or wait until their swing is “ready,” the most common equipment issues like lie angles and shaft weight, and the biggest misconceptions players bring into the fitting bay. Along the way, Nick gives his candid thoughts on how fittings often morph into mini lessons, tells stories from the fitting floor, and offers practical advice for golfers looking to get the most out of the process.

In this listener mailbag episode, we tackle five great questions from our audience. We dive into whether players should use their arms or body rotation to shallow the club, how to compress the ball with an in-to-out swing, and whether short game and putting should be recorded like full swings. We also share our favorite clubface control drills and break down the pros and cons of attending a three-day golf school. It’s a rapid-fire episode packed with insights, practice tips, and coaching perspective.

In this episode, we compare online and in-person golf lessons. Each format has unique advantages and challenges. Erik, Jayson, and Tyson discuss the value of hands-on instruction, real-time adjustments, and subtle feedback like facial reactions to good or bad shots. They also highlights how online lessons can be more affordable, accessible, and flexible, but also more dependent on great communication and student initiative. Whether you’re choosing between lesson formats or just curious about how each works, this episode will help you understand which might fit your game best.

In this episode, we dig into the nuances of grip pressure — how hard should you actually hold the club during a swing? We challenge the old “baby bird” analogy, explore how amateurs and professionals differ in both strength and pressure patterns, and debate when in the swing grip pressure matters most. With supporting insights from leading biomechanists Dr. Sasho MacKenzie and Dr. Tyler Standifird, we unpack whether grip pressure is a limiting factor in clubhead speed, how it affects consistency, and how to train it effectively (as well as whether you should even bother). From transitions to tempo, and training tools to tension leaks, this episode covers why how you hold the club might matter more than you think.

Full quotes from Doctors Standifird and MacKenzie:

Dr. Tyler Standifird:

1. It needs to be trained specifically. I know there are groups who say it is trained just if we do heavy weight training, and that is kind of true, but the specificity of grip strength training is so easy and effective that we all should be doing it. I compare it to like how a bent over row in the gym strengthens your bicep, but that if you really want to get your bicep bigger you do curls.

2. Speed training is not enough, again at least in my experience I don’t think speed training on it’s own strengthens grip, helps you learn I think how to maybe utilize what you have in grip strength a bit better/more efficiently, but again refer back to number 1.

3. I agree with what you say about training it to avoid that slipping feeling. Just met with a player who is doing GRF assessments looking for more speed. He is up to maybe a 124/125 club speed, but is saying he feels the club slip just a bit. His grip strength is around 41 kg in the lead side, starting to be a limiting factor for him, can’t hold onto the club.

I’d say pros maybe apply more force in the swing if that makes sense. So if they are stronger their 8/10 might be 44 kg, vs a 45 year old amateur at 8/10 might be 31 kg. Also even the higher level players I have had on the sensor edge device are not 3/10. Not even close. Lowest I have seen with all my players, pro, amateurs and in between was about a 5.6/10. And that guy had a grip strength of 65 kg, so huge strength. Most people end up in the 7-9 range, regardless of skill level, its more of that patterns that change as players get better.

Using something like the SuperSpeed squeeze can be an effective way to “trick” a golfer into training grip strength when they think they are practicing golf. The fat grip is shown to enhance muscular activation in grip/forearm. So they will get that benefit when they take swings and additionally it will force them to grip down tighter because it feels that the club is going to move out of their hands. This helps them train the feels of developing more force when needed in the swing. Also static grip strength training, gripping something, squeezing something is very effective, no matter that apparatus used. The squeeze training includes these as well.

Dr. Sasho MacKenzie:

I don’t think grip strength, as measured by squeezing something, is important in golf.

I have a lot of thoughts on this. I see people get a lot faster without any change in grip strength. Alos, I can’t think of a single time where a club flew out of someone’s hands because they swung too fast for their level of grip strength.

Any low to moderate correlation between grip squeeze strength and clubhead speed is not causal.

I’ve measured juniors with 120 mph clubhead speed that couldn’t squeeze the juice out of a lemon.

Vijay only had one hand on the club at impact swinging at 120 mph.
