About Sigma
Welcome to Sigma
Sigma Hybrid Training embodies self-reliance and the relentless pursuit of excellence through a comprehensive approach to fitness and health.

We are for those who challenge conventions and take ownership of their journey, aiming to become stronger, faster, and more resilient.
Whether you’re just starting out or are an elite athlete, Sigma Hybrid Training meets you where you are, guiding you to push your limits and achieve personal greatness.
About me
My name is Erick Bouwer, and I’m not just your Head Coach; I’m someone who has been exactly where many of you are or have been. My story is one of transformation, not just in how I look, but in how I feel every single day.
The before picture (mid-July 2023) of me shows a body with little "hidden" muscle and too much fat (to my liking, I must add). The after picture (mid-October 2024), taken just over a year later, tells a different story: lean, strong, and full of energy. But this transformation wasn’t just about looking good.
Today, as a competing Hybrid Athlete, I feel energized, happy and confident 365 days a year. There’s no need for a summer “cut” because I’m always ready. That lasting change didn’t happen overnight. It took discipline, passion, and a structured approach to both training and nutrition.
Why Sigma exists
I founded Sigma to share this journey with you and to guide you through your own. It’s not just about building muscle or losing fat — it’s about creating a sustainable lifestyle that brings out the best in you, physically and mentally. Sigma is about structured coaching programs tailored to your needs. It’s about helping you embrace discipline in the gym and the kitchen and discovering what works for your body. I’ve spent years experimenting, learning, and growing to find a path that works. At 43, I made a significant pivot to vegan nutrition and a hybrid athlete training program, and the results speak for themselves. I believe this approach is worth exploring, and I’m here to support you every step of the way.
The Sigma commitment
Change won’t happen overnight, but if you trust the process, great results are within your reach. The timeline of my transformation — from July 2023 to October 2024 — proves that with consistency, you can achieve anything you put your mind to. As a certified personal trainer and Hyrox Performance Coach, I’m equipped to guide you, whether you’re stepping into the gym for the first time, preparing for a competition, or just looking to feel better in your own skin.

Your journey is yours to own, but you don’t have to do it alone. Sigma is here to provide you with the structure, tools, and encouragement you need to succeed. Are you ready to take the first step toward the best version of yourself? Let’s make it happen — together.
