When I first started this Sub-7 Experiment, the plan was simple, if ambitious: see if modern AI could help me train for and achieve a sub-7-minute 2,000-meter row on the erg. And that’s still the main goal. I still feel the need for progressive overload, for pushing myself, for having a clear target that gets me to the gym.
But something else happened along the way. Something deeper. The experiment has evolved into much more than just a number on a screen. It’s become an unexpected anchor in my life, bringing with it a whole host of perks I never anticipated.
Movement as a Mental Reset
Initially, the goal was physical fitness, changing shape for a holiday. But quickly, I realised something else was at play. Movement, especially rowing, became my mental anchor. I’ve come to rely on it as a mental health row or a head leveller.
When my head’s all over the place, after a long work drive or in the middle of something stressful, going to the gym isn’t just physical. It clears the fog. Even a walk in the woods on the way home from a tough meeting now brings me back to myself.
ChatGPT, my digital coach, has helped me see these shifts more clearly. It often points out the real wins I’d otherwise miss.
Busting the “Lazy” Myth
For a long time, I called myself “inherently lazy.” It’s a story I’ve told myself for years. But this experiment has quietly dismantled that.
I now know I’m consistent. Not just when it’s convenient, but when I’m tired, travelling for work, feeling flat, or battling the inner critic. The gym has gone from “something I should do” to “something I need.” It’s no longer about guilt. It’s about feeling right. That shift in motivation is huge.
The Evolution of Identity
The biggest surprise? A shift in how I see myself.
I’ve lived with impostor syndrome for years, always asking: “Am I really this person?” But by showing up, pushing through, and reflecting, I’ve realised, yes, I am. And I deserve to be.
It’s not about perfect sessions. It’s about making the average ones count. That’s the real change. I’m becoming comfortable with this version of me. I’ve never said that before. And that kind of self-acceptance is worth more than any split time.
Beyond the Gym: Life Benefits
The habits built in this experiment are bleeding into other areas of life.
I’ve learned to set boundaries, like leaving my work phone in the car during walks. It means I show up properly at home instead of still being “at the office in my head.”
I’m more mindful of hydration and how it affects mental clarity. And even though the scale doesn’t always move the way I want, I’m fitting into old clothes. I feel stronger, fitter, even if my body image takes time to catch up to reality. That reminds me: health isn’t a number. It’s how you feel in your skin.
ChatGPT’s flexibility has been a game-changer too. When my shoulder’s acting up, or recovery’s low, or my mood’s off, the plan adapts. And that means I stay consistent, avoid injury, and keep moving. It’s about training smart, not stubborn.
This is still the Sub-7 Experiment.
But it’s about much more than rowing.
It’s a framework for handling life. A journey of self-discovery.
And a reminder that consistent, intentional movement can anchor you in a messy world.
