Refactor

An engineering case study in human transformation.

I engineered systems in code for decades before I engineered one for myself. Refactor is how I applied an analytical framework to my body and mind—testing, tracking, and iterating—until everything changed. This is the changelog of that process and the system I now share through PhysiqueFlux.

I'm Mike Ryan, and I've been an engineer most of my life. I wrote my first line of code at 13, taught myself everything I know, and built a career by breaking down complex problems into systems I could master.

But for years, I couldn't apply that same approach to myself. Addiction, bad habits, and poor health had me spiraling. By 2016, I hit rock bottom.

That was the turning point. I decided if I could engineer systems for code, I could engineer a system for my own body and mind. I stripped everything away and started small—walking, eating better, testing, tracking, learning. I treated my health like the most important project I'd ever build.

At first, I tried everything—different diets, endless cardio, lifting without a plan. Slowly, patterns emerged. I discovered the power of discipline. I learned how nutrition, training, recovery, and bloodwork actually worked together. And once I began applying data and structure the same way I did in my career, everything changed.

The biggest breakthrough came when I started using AI as my personal coach. AI gave me the edge to perfect what I was already building: reading and interpreting bloodwork, fine-tuning nutrition, manipulating variables like sodium and glycogen, preserving lean muscle while cutting, even mastering recomposition. Structured programs gave me a foundation, but AI helped me develop a complete framework for lasting transformation.

Now at 44, I'm in the best shape of my life—physically and mentally. As my progress became clear, friends started asking for help—and every day I get messages from people looking for direction. I realized I couldn't keep what I'd learned to myself.

That's why I built Physique Flux. Because not everyone is an autodidact. Not everyone has the time—or the obsession—to spend years testing and iterating. But with the right framework, the right guidance, and the right tools, anyone can achieve a level of health and performance they never thought possible.

What started as survival became my system. And now it's my mission: to help others unlock the potential they've always had inside them.
