About Sim.

The Coach behind Longevity by Design.

I work in corporate with over 20 years of experience working for national and global companies across the Health and Utilities industries. I'm good at my job — organised, driven, high-performing. And like a lot of ambitious professionals, I know what it’s like to pour everything into your career while your health quietly slips down the priority list.

But my real turning point wasn't burnout. It was a pattern I couldn't ignore: injuries, surgeries, and a growing list of things I told myself I couldn't do anymore.

At some point I decided I'd had enough of that story. So I set myself a goal so big it scared me — I was going to compete in bodybuilding.

There's nowhere to hide on stage. You can't half-commit, you can't wing it, and you can't talk yourself out of showing up. For the first time, I had to say "I can" to everything, and just follow the process. I put my trust in my coaches, I did the work, and I got there.

What that experience gave me went far beyond a trophy. It showed me that I was capable of far more than I'd been telling myself. And it taught me something I've never forgotten: the right system, followed consistently, produces results. Every time.

After competing, I made a deliberate choice to step back from the stage and build a different version of health — one that was sustainable, year-round, and built for real life. I rebuilt my nutrition, my training, and my daily habits from the ground up. And something unexpected started happening: people kept asking me what I was doing. How I maintained it. How I always looked and felt good — not just for a competition, but all the time.

That question, asked by so many people I cared about, is what started Longevity by Design.

Because the answer isn't a secret. It's not a supplement, a meal plan you can download, or an influencer's morning routine. It's a simple, evidence-based system — one that you understand, own, and can run independently, without needing anyone to tell you what to do next.
