C3 Training Gymea

Try our 7-Day FREE trial now.

Here at C3, we're a little different.

We focus on community. We set out to build a gym where people feel like they want to go, and not to go. Friends train free every Saturday, 

We focus on coaching. We don't do 'seconds on and seconds off'.  We provide structured Strong, Hybrid, or Energy classes over a 15 week program to help you achieve your goals.

We focus on care. Be it post-partum, or Olympic athlete (yes - we have a few of those), we want to help each of our members achieve their health and wellness goals.

Meet The Trainers

Work with coaches that really care about your goals and tailor classes to your needs.

Nate Kelly

Hi everyone, my name is Nate, I am the head trainer at C3 Gymea.


My passion is to help people change their lives in the simplest and most realistic ways possible. I started my career as a diver in the Navy and developed my mindset around what it takes to succeed both physically and mentally in some of the most unforgiving environments imaginable. But don’t let that scare you, I believe everyone deserves the right to good health and to be happy with themselves inside and out. 

I bring over 18 years of coaching and fitness experience. I honed my techniques firstly on myself as a representative 400m track and field athlete, and now help our members reach their goals. I care deeply about my clients, and there’s nothing of more value to me than helping somebody go through an experience that makes them happy, confident, and strong.

When you train with me, I’ll help you discover the benefits and joys of fitness that helped me become the person that I am today and guide you on every step of your personal journey.
