The Story

I'm Reinier Geyser — most people know me as Coach RG.

I started in the fitness industry more than 30 years ago. From the beginning, I've been driven by curiosity: How can we train better, build lasting habits, and turn better health into a better life?

That curiosity has kept me learning, evolving, and looking ahead. As fitness has changed, I've continued exploring new approaches, testing them through my own training and coaching, and bringing practical ideas into the programs I create.

My purpose has stayed constant: help people discover what they're capable of — and give them the guidance to act on it.

100 Healthy & Happy.

Your next chapter deserves

the strongest version of you.

Experience That Gives Your Training Purpose

My journey has taken me through 54 marathons, four Ironman finishes, mountain expeditions, and endurance challenges that demanded patience, preparation, and resilience.

Those experiences shape how I coach. I understand the work behind a meaningful goal, the uncertainty of starting, and the confidence that grows when you accomplish something you once thought was beyond you.

Whether your goal is to feel stronger each morning, keep up with your family, cross a finish line, or stand on a mountain summit — your training should help you get there.

"I don't share this to impress you. I share it so you know I've lived what I teach — and I know what's possible when you commit to the work."

— Coach RG

Measurable Progress. Lifelong Memories.

I create fitness programs built to deliver measurable results and open the door to experiences you'll remember for the rest of your life.

We build strength, endurance, mobility, and daily habits with a purpose: helping you participate more fully in the things that matter to you.

Sometimes progress means lifting more or walking farther. Sometimes it means having energy left at the end of the day. And sometimes it means sharing an adventure with your child that you'll both talk about for years.

That is what EPIC90 is built around: personal coaching, clear goals, accountability, and opportunities to put your growing capability to use.

Strength gives us freedom.

Health gives us options.

Confidence allows us to say yes when life calls.

The EPIC90 Promise

What does feeling 10 years younger actually mean?

Waking up with more energy.

Moving without pain.

Having the strength to do the things you love.

Feeling confident in your body again.

Being ready when adventure calls.

In 90 days, you can build momentum. In a year, you can transform your life.

Your Next Chapter Is Worth Training For

After more than three decades in this industry, I'm still curious, still challenging myself, and still excited to help people move forward.

Strength is the foundation.

Muscle is your armor against aging. We build it deliberately, progressively, and sustainably — not to look good, but to stay capable.

Habits outlast motivation.

Motivation is a spark. Habits are the engine. We build the daily disciplines that compound into a completely different life.

Adventure is the goal.

The workouts are the vehicle. The destination is a bigger life — one where you can say yes to the experiences that matter most.

The second half is the best half.

You don't need to arrive fit or confident. We start where you are and build from there. Bring a willingness to begin — I'll bring experience, a plan, and a commitment to helping you follow through.

Add Muscle. Add Endurance. Add Life.

The first step is an honest conversation about where you are and where you want to go.

Because your next chapter deserves the strongest version of you.
