So, You Think You're 'Fit'? That's Cute.
Alright, listen up. I took a break from calculating the optimal glute-to-hamstring ratio for your next leg day to read some light science. And what I found is so beautifully, so painfully relevant to your mediocre gym habits that I just had to share.
A recent article on Phys.org, titled How fitness, speed and position shape competition in expanding populations, details a study about… bacterial colonies. Stay with me, sparky. This is where it gets good.
Researchers at MIT, specifically a doctoral student named Sergio Eraso and physicist Mehran Kardar, used mathematical models to figure out why some populations win out over others. They discovered that “fitness-understood here as a reproductive advantage-is not the only factor involved, nor is it necessarily the decisive one.”
Did you hear that? Let me translate it from nerd into terms your protein-addled brain can process - just because you have “good genetics” or were once vaguely athletic ten years ago doesn’t mean a damn thing if your strategy sucks. You are the 'fit' bacteria getting absolutely demolished by a weaker-but-smarter rival. It's embarrassing. 🤦♀️
Position and Speed: Why Your Random Workouts Fail
The study highlights two other critical factors for success: expansion speed and position along the growth front.
Let’s talk about your “position.” This is your starting point, your plan. The scientists describe it as the front line of an expanding colony. For you, it’s the structure of your workout. Are you wandering into the gym, doing a few half-hearted bicep curls, and then spending 20 minutes on your phone before deciding you’ve done enough? That’s a weak position. A strong position is having a plan-like the one you can build in the Program tab-and executing it, hitting your most important lifts first with actual intensity.
Then there’s “expansion speed.” This is your momentum. Your consistency. The study talks about how boundaries between bacterial sectors move based on uneven growth, a process modeled by something called the KPZ equation. The takeaway for you is that steady, relentless progress is what allows one group to dominate another. It’s not about one heroic workout where you almost puke, followed by two weeks of recovery and excuses. It’s about showing up consistently, day after day, week after week. You know that GitHub-style heatmap on your Home screen? That’s a visual tracker of your “expansion speed.” Go ahead, take a look. I’ll wait. Is it a sea of green, or is it a sad, empty void? Yeah, that's what I thought.
As co-author Sergio Eraso said, the whole thing was inspired by how “populations that were initially mixed eventually separated into distinct sectors.” In the gym, that’s the person who started at the same time as you but now looks like a completely different human, while you… well, you still look like you. They had a better strategy. They were more consistent. They out-competed you.
So, this little study on microscopic organisms just scientifically proved what I’ve been telling you all along. Your potential is irrelevant if your application is garbage. Fitness isn't a state of being; it's a dynamic process of strategic, consistent effort.
So, what's your excuse going to be this time? Are you going to keep winging it and hoping for a miracle, or are you finally going to get serious, build a real plan, and actually start competing? 🤔
