What My 6 AM Gym Class Taught Me About Marketing [Two on Tuesdays]


Happy Tuesday, Reader!

Last week, we talked about Sustainable Marketing Principle #4: building an intentional word-of-mouth and referral strategy. This week, we're moving to Principle #3: marketing is the heartbeat of the company, not an appendage.

While it’s often treated as an afterthought, sustainable marketing is part of a business's DNA, deeply aligned with its goal of service and its values. When it's disconnected from either, it stops working the way it should.

Where I See This Principle in Action

To be clear, the business I'm about to tell you about isn't a client. I don't know if they'd even use the words "marketing strategy" to describe what they do. But nowhere have I seen this principle more clearly than at my gym, Sol Fitness, every single time I'm sweating there at 6 am.

And while I didn't invent this idea that marketing lives inside how a business shows up, rather than something bolted on after the fact, I’ve spent almost two decades observing it in action. We built a system around it for our clients because I kept seeing it show up in the best, most connected community-based businesses. Sol just happens to be where I see it most clearly right now.

The Marketing That Doesn't Look Like Marketing

On any given weekday morning, Sunny and the team are filming. That footage eventually shows up in Sol's marketing, but that's not really what it's for. It's there to help us see our own progress. It shows real people doing real work on their bodies, not aspirational models or airbrushed fitness pros. Just the people actually in the room.

That commitment to real people building resilience and joy through movement is what brought me to Sol in the first place. It's what keeps me coming back three to four times a week. And it's not a campaign or a content calendar, but a pulse that’s there in every class, every private session, every single day. It's underpinned by the savvy strategy of co-owner and marketing industry veteran Stephanie Melvin, but it doesn't feel strategic when you're living it. It just feels like who they are.

Why This Is What Sustainability Actually Looks Like

True sustainability happens when marketing isn't its own department, campaign, or separate thing you do to your business. Instead, it’s the sustaining rhythm of how the business shows up, every day. That's growth measured in years, not quarters.

Most of us treat marketing like a task on a to-do list. Sol treats it like a byproduct of just doing the work well and documenting it honestly. The strategy isn't separate from the service. It is the service, witnessed.

This week, ask yourself: Is your marketing something you do, or something you are? If someone filmed a random Tuesday at your business, would it match what you're already putting out into the world, or would your marketing turn out to be telling a different, more polished story?

And, what's one small thing you can start this week to bring your marketing more in line with who you are as a company?

Until next time,

Happy Tuesday, Reader! We've made it to the last of our 5 Principles of Sustainable Marketing: long-term thinking. In a zero-click digital world (and one where the phone in your pocket is competing for your attention even while you're standing in a physical room with actual people), the discipline of thinking in long-term story arcs has become a superpower precisely because almost nobody is doing it anymore. Marketing has become about optimizing for the next scroll, the next quarter, the next...

Happy Tuesday, Reader! Last week, we talked about Sustainable Marketing Principle #3: marketing as the heartbeat of the company. This week, we're on Principle #2: build on a values-driven framework. A values-driven framework starts with getting clear on your 3-Core: your core values, your core beliefs, and the core communities you're built to serve. Get those three things right, and you have a foundation solid enough to stand on, no matter what’s happening around you. Many people view...

Happy Tuesday, Reader! My team and I have had the privilege of building Mrs. Grout's website three times now. Each version gets a little sharper, a little more polished, a little more them. With each iteration, the web work gets a little easier. Partly because we’ve gotten better at our job, but mostly because Mrs. Grout's reputation does most of the heavy lifting before a visitor ever lands on the site. Sustainable Marketing Builds a Reputation, Not Just a Website. Last week, we kicked off...
