  • Reflection: More Than Just a Rowing Goal

    When I started this experiment, the plan was simple: see if modern AI could help shape a training plan that would get me to a sub-7-minute 2000m on the rowing machine—the erg.

    And that’s still the plan. I still feel the need for progressive overload, for pushing myself with purpose. I still need a reason to get to the gym.

    But the experiment has shifted. More on that in a moment.

    First, a quick word on the AI itself.

    I’ve been using a large language model—ChatGPT—a type of generative AI. “Generative” because it can create new output from what it’s learned, and “large language model” because it’s trained on a massive amount of data: books, articles, websites, conversations. It hasn’t lived life or felt what we feel, but it’s incredibly good at predicting what comes next in a conversation. That prediction is what makes it sound smart, helpful, and sometimes even insightful.

    That’s what’s happening here. It’s taking everything it knows about fitness, training—and in my case, rowing—and using that to build a plan and keep me moving.

    I haven’t posted every single conversation in this blog. There are lots of sessions behind the scenes. Things I’d probably never ask a personal trainer in real life. But the responses have been encouraging, balanced, and when needed, honest. I’ve even asked it to cut the fluff and just tell me straight. And it has. No judgement. Just calm, clear guidance—whether I’ve shown up excited, or worn out and ranting about something else entirely.

    More than anything, this process has made me look at myself differently.

    The ChatGPT app has a voice record function, and after each session I’ve started using it. What comes out is often a stream of consciousness. Frustrations. Wins. Questions. And then it plays things back to me in a way that makes me actually listen.

    And what have I learned?

    For one, I understand the technology better now. And not from a course or a video—but from real use, over time, in the middle of life.

    But more importantly, I understand myself better.

    I’ve learned that I’m consistent. Not just when it’s easy—when I’m tired, on the road, or in a funk, I still show up.

    I’ve learned that I’ve changed my default settings.

    I used to say things like, “I’m lazy,” or “I always self-sabotage.”

    But that’s not true anymore. I’m training differently. Responding to setbacks differently.

    Movement has become my anchor. A reset. A reminder of who I am and what I can handle. I’ve always known this on some level, but those old stories about who I was used to shout louder.

    Not anymore.

    The biggest shift?
    I now believe I can be the person I want to be.

    Impostor syndrome has run the show for a long time. The voice that asked, “Am I really this person?”

    Now I know: Yes. I am.

    And I deserve to be.

    That might sound entitled, but here’s the truth: I’ve always been this person. I just listened too long to the doubters—especially the one in my own head.

    I’m not saying every day is easy. I’m human.

    But I’m learning to spot the hard days sooner. I’ve got tools now. And more importantly, I’m using them.

    And here’s the bit I never expected:

    I’m comfortable with this version of me.

    And that’s something I’ve never said before.

    Rowing Machines – Lurking in the Shadows

    Rowing machines. You’ve seen them. Lurking somewhere in the back of the gym, pushed up against a wall, out of the way. More often than not, they’re gathering dust, untouched, while people hammer away on the treadmills or load up the bench press.

    I’ve had a long, love-hate relationship with these things. Never really knew how to use them properly. Never really cared, if I’m honest. Every now and then, I’d climb aboard, crank the handle on the side to somewhere in the middle, start pulling, and within minutes, be gasping for air, sweating like a pig, and regretting every life choice that had led me to this moment.

    But then—once I was done, once I dragged myself off the thing, hot, sweaty, and totally wrecked—there was a buzz. A moment of satisfaction. I’d conquered the beast.

    And then I’d ignore it again for months.

    This went on for years. If I was in a hotel gym by myself, I’d maybe give it five minutes between the bike and the sauna. Or between the bike and the restaurant. Same thing.

    Then, a few years ago, something changed. My relationship with the ERG—yes, that’s what they’re properly called (I’ll get into that in another post)—shifted completely.

    It started with my son’s swimming lessons.

    Every Saturday, I’d take him to a local hotel with a great swimming pool and gym. While he had his lesson, I’d sit in the hotel lobby, drinking coffee, eating scones, and feeling very pleased with myself. That was my routine.

    Then the hotel gym ran a ridiculous deal on family memberships. We signed up, and suddenly, instead of coffee and scones, I was in the gym.

    At the time, I was into cycling, so I stuck to the static bike, grinding away for 30 minutes while keeping an eye on my son’s lesson. But every session, out of the corner of my eye, I could see it.

    The ERG.

    Just sitting there. Watching me. Daring me.

    And one Saturday, I gave in.

    I climbed on, set the dial somewhere in the middle (because I still had no clue what I was doing), and started pulling. And panting. And sweating. Five minutes in, I was closing in on 1,000 meters, so I figured—why not? Might as well push through. Seven minutes in, I hit 1,000m. Maybe I could get to ten minutes? My legs were screaming, my lungs were on fire, but I refused to stop.

    Forward. Backward. No technique. No idea. Just sheer bloody-mindedness.

    And then—2,000 meters.

    I stopped. Absolutely done. But something clicked.

    That was the start of something. From then on, every week during my son’s swimming lessons—and whenever else I could fit it in—I came back. I pushed further. Rowed harder. Lasted longer.

    Now, rowing is a central part of my life—not just physically, but mentally too.

    This blog, The Sub-7 Experiment, is a record of why I row, how I’m chasing a sub-7-minute 2K, and everything I learn along the way.

    Let’s see where this goes.
