Three Common Club Fitting Mistakes That Derail Improvement

A golfer adapts to whatever is in their hands. As a coach, that isn’t a piece of trivia. It’s a variable in every session. The player who walks onto your lesson tee has already organized their body around their equipment, long before you saw a single rep.

That’s the part that quietly sabotages good work. Poorly fit clubs train compensations, and then you spend lessons fighting a motor pattern that the equipment is actively rewarding. You can be completely right about the change you’re prescribing and still watch it fail, because there’s a third party in the room: the club.

This is why club fitting has to be married to instruction. When the fitting is dialed in, the coaching and the clubs pull in the same direction. When it isn’t, you’re coaching uphill. As Dave Phillips puts it: “Make sure your clubs are working toward where you want to go, not stopping you from where you want to go.”

In the video below, Dave Phillips and Dr. Greg Rose outline three of the most common ways a club ends up working against the work you’re trying to do.

 

1) The Club Was Fit to the Fault, Not the Goal

When a player’s clubs were fit around a swing characteristic, they tend to reward that fault rather than the new goal.

Early extension is the textbook case. When a player early extends, with the pelvis pushing toward the ball through impact, the handle and shaft raise up and the strike can scatter off-center. Plenty of fittings “fix” that by bending the hosel more upright. While it works in terms of improving ball flight, now they are using a club that was built to function only if the player keeps early extending. The equipment now matches the fault.

We deal with the identical problem at the elite level; it’s just solved differently. On the PGA Tour there’s a trailer that follows players around and re-adjusts their clubs if their swings evolve. Your players don’t have a trailer so you are the one who has to flag when it’s time to re-check the build.

The better model is to fit toward the goal, not the fault. Sometimes that means deliberately building a club the player would hate if they reverted (flatter, in the early-extension case) so the equipment reinforces the pattern you’re coaching instead of bailing them out of it. Fit the swing you’re building, not the one you’re trying to retire.

2) Strengthening Lofts for Distance (and Manufacturing a Compensation)

The trend toward stronger lofts is easy to understand: bend a 7-iron to a 6-iron loft and it flies farther and flatter, and a new 7-iron that outdrives the incumbent can be easier to sell. But the cost can show up in the body. When lofts get strong enough, a player looks down at almost no loft and instinctively adds it back, side-bending and hanging back on the trail side to help the ball up. Repeated every swing, that compensation is a common source of the trail-side loading that later presents as wrist, arm, and low-back issues. The equipment can manufacture the very fault you end up treating.

Elite players tend to go the other way. With the mechanics to lean the shaft forward at impact, they de-loft the club themselves, which lets them play weaker lofts and use a better swing to take loft off rather than fighting to add it back.

The coaching takeaway is to fit for efficiency rather than just for distance. Distance is the product of ball speed, launch angle, and spin rate, and the metric most often sacrificed by strong lofts is landing angle: the ball arrives too flat to hold a green regardless of how far it carries.

Anchor every loft decision to strike. Center-face contact produces the highest ball speed and the best directional control, and it’s the foundation the rest of the fit is built on. Fit the loft to the swing, not to the number stamped on the sole.

 

3) Players (Especially Juniors) in Clubs That Are Too Long

Club length is the easiest fit to misjudge, and the easiest to screen. Stand a player next to a standard 45-inch driver and the grip should sit a couple of fingers above the belly button. On many juniors, a hand-me-down driver reaches the sternum. A club that long is nearly impossible for even a grown adult to control: the shoulder plane flattens and the wrists and arms load in ways they aren’t built for, which is the same pattern that shows up in young players handed clubs they can’t physically organize around.

This applies to nearly every player: shorter clubs are easier to control and strike consistently. Even among adults, the data favors restraint. At TPI, roughly 75% of players leave with a 45-inch driver, about 20% near 44.5 inches, and only about 5% go longer. A longer club can post a faster clubhead-speed number, but if the player can’t find the center of the face, that’s consistency traded for a figure that never reaches the scorecard. The answer is rarely “longer”; it’s centered, repeatable contact.

Weight follows the same logic. Too heavy invites swing flaws. For juniors the guideline is simple: keep them in clubs as light and as short as possible for as long as possible, so the swing grows with the athlete. An uncontrollable club in a young player’s hands doesn’t just slow development; it can build a flawed motor pattern that takes years to undo.

 

Make Fitting Part of Your Process

Before concluding that a player can’t make a change, or that a body keeps breaking down despite good work, check the club. Equipment is the quiet third party in the room, and more often than it gets credit for, it’s what undoes the session. The professionals who get the most from their players treat fitting as part of the program rather than a separate errand: they build it into the screen, partner with a fitter they trust, and treat the build as a moving target that keeps pace with the swing they’re developing.

We’ve updated the fitting section in Power Level 2 to support this integrated approach in order to maximize efficiency, covering club-head and loft assessment, strike efficiency, landing-angle and Trackman fundamentals, and shaft characteristics like length, weight, and profile. And because fitting and instruction work best together, it’s worth building a relationship with a qualified fitter who can see the swing and the numbers alongside your work.
