I’m going to tell this story exactly how it happened, embarrassing parts included. I withdrew from the Admiral Baker Club Championship this week — the same event where I finished 2nd last year — because of a swing speed training injury I gave myself. Not from golf. Not from competition.

From my own overspeed session, on the final 195-gram set that closes out every Stack workout, doing something I’d never tried before. This is the honest breakdown of how one swing speed training injury cost me a shot at a title I’d been chasing for three years, and what I’m changing because of it.

What Happened During My Swing Speed Training Injury

I was in the middle of Stack Session 14 of 24 in Program 8. Fourteen sessions in, my body knows the protocol cold — light stick, mid stick, stack, all with a warmup and a rhythm I’ve repeated over 5,400 swings across seven completed programs.

That familiarity is exactly what set up this swing speed training injury. I felt loose, confident, and a little too willing to experiment on a day I should have just executed the plan. Seven completed programs without a single setback had made me a little too comfortable with the process — comfortable enough to think I could bend the rules on session 14 of my eighth run through it.

For context on how much trust I’d built in this system: I started Program 1 at 89 mph. By the end of Program 7, I was sitting at 111 mph, tracked session by session on that same 195-gram eSpeed set I mentioned above. Seventeen months of gains, over 5,400 total swings, and not once in that stretch did I feel the need to change what the protocol was already asking me to do. That track record is what made this particular lapse so frustrating — I had proof, in my own numbers, that following the plan works.

The Session Where My Swing Speed Training Injury Happened

The night before, I’d gone down a YouTube rabbit hole on creating more separation in the downswing — keeping the hands and upper body working a beat ahead of the lower body so the club has to “catch up,” building speed through that stretch.

I’ve never coached myself off a video mid-program before. Every one of my Stack System results has come from trusting the protocol, not freelancing. That’s what got me from 89 mph to 111 mph over 17 months — sticking to the plan, session after session, without inventing new mechanics in the middle of a max-effort set.

This was the first time I broke that rule, and I picked the worst possible set to try it on. Looking back, the swing speed training injury I gave myself started the night before, on the couch, watching a technique breakdown that had nothing to do with my actual training program.

What makes it more frustrating is that separation isn’t even something the Stack protocol ignores. The program is already built around sequencing the body correctly through every stick in the set — that’s the whole point of overspeed training done right. I didn’t need to borrow a concept from a golf instruction channel and layer it on top of a system that was already working. I just wanted to feel like I was doing something extra, and that urge to add one more thing on top of a program that was already delivering results is the real root cause here, more than any single video.

Why I Was Chasing Separation at 195 Grams When the Swing Speed Training Injury Occurred

Every Stack session ends with the same 195-gram set — not the heaviest club in the protocol, but the one constant I always keep an eye on because it’s how you track eSpeed. It’s the number that tells you whether you’re actually gaining speed over time.

That’s exactly why it’s the worst possible place to test something new. I told myself I’d just try to hold my hands and upper body a little higher through transition to create more separation before the release. Earlier in the session, on a different stick, maybe that’s a harmless experiment.

On the set that tracks my eSpeed, on the last swing, it wasn’t. A swing speed training injury doesn’t usually announce itself in advance — it shows up disguised as a small tweak on a set you’ve done hundreds of times before without incident.

The Exact Swing That Caused My Swing Speed Training Injury

On the last swing of the set — the fastest one, the one I was pushing hardest on — I kept my hands high to create that separation.

My body reacted the way bodies do when you ask for more speed than your current mechanics are built to deliver safely. My neck turned harder and faster than normal to help generate that extra separation into the downswing. I felt it the instant I finished the swing.

Not pain exactly at first, just a wrongness, like something had been asked to do a job it wasn’t warmed up for. That wrongness turned into a full swing speed training injury within the hour.

Looking back at it now, I can walk through exactly why it happened. My core rotation and diagonal pull are already my weakest links according to my TPI numbers, which means my neck and upper back end up compensating any time I ask for more speed than my hips and core can generate on their own. Keeping my hands high for separation put even more of that load on the exact area least equipped to handle it. It’s a simple equation in hindsight — ask a weak link to do a strong link’s job at maximum effort, and something eventually gives.

How My Swing Speed Training Injury Forced Me to Withdraw From Admiral Baker

By that evening I couldn’t turn my head to the left at all. Not “tight,” not “sore” — genuinely couldn’t get there.

The Admiral Baker Club Championship was the next day, a tournament run by my men’s club at Admiral Baker Golf Course, where I’ve been a member the past 3 years and where I’d finished in the top 5 the past couple of years.

There was no version of showing up unable to rotate my neck through a backswing, let alone competing for two rounds. I made the call to withdraw that morning. A swing speed training injury that keeps you from turning your head left isn’t something you play through — it’s something you respect.

Admiral Baker’s club championship isn’t a casual event for me. I’ve been a member there for three years, and it’s the tournament on my calendar I circle every season — the one where I actually know the course inside and out, know the members I’m competing against, and have a real sense of where I stack up year over year. Finishing in the top 5 the past couple of years had me thinking this could finally be the year I got over the hump. Instead, one swing on an overspeed stick took that chance off the table before I even hit the first tee.

The Symptoms of My Swing Speed Training Injury, Hour by Hour

The morning after, things had loosened somewhat. I could turn my head, just not fully, and I tested a few swings at what felt like 50% effort.

The speed wasn’t there and neither was the power — no surprise, since the whole system that generates 111 mph runs through core and neck rotation, and mine was locked down defending itself. Trying to force speed through a compromised range of motion is exactly how a one-day swing speed training injury turns into a multi-week one, so I backed off entirely.

I’ve read enough about overspeed training in general to know that neck and cervical strain isn’t unheard of when you’re asking the body to rotate faster than it’s used to, especially once fatigue sets in late in a session. It’s just not something I’d personally run into before in over 5,400 swings, which is part of why it caught me off guard. The takeaway I keep coming back to is that a body that’s handled thousands of reps safely can still get hurt the moment you change one variable at max effort — the volume of past reps doesn’t buy you immunity on a new movement pattern.

What My Swing Speed Training Injury Taught Me About Training Discipline

This one stings more than a bad round ever could, because it was entirely avoidable. My TPI assessment already flagged my core rotation in the 20th percentile and my upper body diagonal pull in the 14th percentile.

I knew, on paper, that rotational speed was my limiter and my risk zone. And on the one day I decided to freelance a new move at max weight, that’s precisely where it broke down.

The lesson isn’t subtle: know your own data and still find a way to ignore it in the moment. A swing speed training injury is rarely random — mine was sitting in my TPI numbers months before it actually happened, waiting for the one day I stopped respecting the protocol.

A TPI screen looks at how your body actually moves — hip mobility, core rotation, shoulder-to-hip separation, that kind of thing — and scores you against other athletes so you can see where your physical limitations are before they show up as swing faults or, in my case, as an injury. My screen flagged full-body rotation in the 31st percentile and 12% left-side dominance on top of the core and upper body numbers I already mentioned. None of that is a mystery I can claim I didn’t have access to. It was printed out, sitting in a folder, months before I decided to test a new hand position on the fastest swing of the day.

Preventing Your Own Swing Speed Training Injury: Lessons From Stack Program 8

If you’re running your own Stack System program, here’s what I’ll be doing differently starting with the rest of Program 8.

Any new technique idea gets tested on the lightest stick first, never on the 195-gram set that closes the session. New moves don’t get introduced late in a session when fatigue is highest — that’s exactly when a swing speed training injury is most likely, because form breaks down first and judgment breaks down right after it.

And anything involving more aggressive rotation gets run past what I already know from my TPI screening before I try it, not after I’ve hurt myself trying it. If you’ve had your own TPI screen done and it flags rotational limits like mine did, take it seriously — it’s the clearest early warning system against a swing speed training injury that most amateur golfers never bother to check.

A few other things I’ll be sticking to for the rest of Program 8 and beyond: full warmup every session, no exceptions, even on days I feel loose walking in. No technique changes copied from a video the night before a session — if something’s worth trying, it goes on the list to bring up with a coach first, not straight into a max-effort set. And if a rep feels different in a way I can’t explain, that’s the rep to stop on, not push through. A swing speed training injury usually gives some kind of warning sign in the moment; the mistake is deciding to finish the swing anyway.

Getting Back on Track After a Swing Speed Training Injury

For now, the plan is simple: no swinging until I have full, pain-free rotation back.

My next Stack session is due in the next 3 days, and if I’m not able to swing by then, it’s going to hit my grit score — the consistency metric that comes from not missing sessions. That’s a real cost of this swing speed training injury I hadn’t even thought about until now, on top of the missed tournament.

The pursuit of 115 mph, documented since I started this journey at 89 mph, isn’t going anywhere. But I’d rather take the grit score hit than turn a strained neck into something that costs me the rest of the season. A short-term dip in consistency is a much smaller price than a long-term setback from a swing speed training injury I made worse by rushing back.

I’ve built this whole journey on being honest about the numbers, good and bad — the SG data that shows my putting leak, the TPI percentiles that show my physical limits, and now a grit score dip that shows I missed sessions because of a mistake I made myself. It’s not comfortable to publish, but it’s the same standard I’ve held every other part of this site to since day one, and I’m not going to start hiding the ugly weeks now just because this one is on me.

The 365-Day Reminder: Living With One Swing Speed Training Injury

I finished 2nd at Admiral Baker last year and genuinely believed this was the year to win it. Instead I’ll spend the next 365 days with a very specific memory of exactly how I talked myself out of the protocol on one swing, at one session, chasing a move I saw on YouTube the night before.

That’s the real cost here — not just a missed tournament, but a mistake I get to sit with for a full year before I get another shot at that trophy. If nothing else, it’s proof that the mental game covered in my piece on the mental side of speed training applies just as much to discipline in the training bay as it does on the course.

I’m logging this one in my speed log for good, right next to a note: stick to the protocol. One swing speed training injury, one lesson, 365 days to prove I learned it.

To anyone else running an overspeed program, chasing a number, or building toward their own club championship — take this as the cautionary tale it’s meant to be. The gains are real, the system works, and none of that changes because of one bad decision on one set. What changes is how carefully you protect the process that got you there in the first place.

If you’re chasing swing speed the way I am, the Stack System is still the training I trust — you can check out the same program I use, with a discount applied automatically, here. Just don’t do what I did on the last set of the day — trust the protocol, save the experiments for the light stick, and let the numbers build the way they’re designed to.
