Programs

class.

Stronger together. Results that last.

Every GROUPFIT41 class is a 45‑minute workout led by a certified coach. You’ll build strength, tone up and keep showing up, with a crew that holds you to it.

Your coach takes you through every movement with barbells, dumbbells, kettlebells and cables, on lifts that work: squats, deadlifts and bench press. Each class runs in three blocks: strength and power, muscle building, then cardio and plyometrics.

Real coaching, a room full of energy, and a stronger you every time you walk in.

I have over 25 years in the industry. I have worked for gyms, residences, in‑house private companies, and freelance.

Whether you are out of shape or looking to reach the next level in your training, we will work together to create a healthier you and improve your overall quality of life.

I also provide a program catered to your needs and monitor your progress to ensure maximum results. Together we will work to define success and set tangible, measurable goals. “If you don’t measure it, you can’t improve it.” With me as your trainer, you will reach new heights, leave each session feeling better than before, and want to incorporate your new discipline into every part of your life.

Dr. Mitch Harvey

My name is Dr. Mitch Harvey. I am a chiropractor, certified strength & conditioning specialist, and nutrition coach with a special interest in resistance training, rehabilitation and persistent pain. I draw on all aspects of my experience to provide individualized coaching centred around exercise, education and progressive programming designed to make you more resilient and capable.

On the personal training side, I have always loved working out for sports and for my own health and fitness. Working with clients, I aim to create an environment where you feel supported, informed, and empowered to achieve short and long-term progress. You can expect a collaborative process grounded in the best available evidence, with clear steps that move you toward the activities and lifestyle you value most.

I believe fitness should feel empowering, not intimidating. My own fitness journey has taught me that getting stronger is not just about how much you can lift. It can change the way you feel about yourself, the way you move through everyday life, and the confidence you carry with you outside the gym. Over time, I’ve come to appreciate fitness as something that can evolve with you through different stages of life.

That perspective shapes the way I coach. I’m passionate about helping people build strength, confidence, and trust in what their bodies can do. Whether you are brand new to the gym, getting back into exercise after some time away, or navigating a significant life change, I am here to support you.

My areas of focus include strength training, functional movement, flexibility, balance, and overall wellness. My coaching style is encouraging, adaptable, and down‑to‑earth. We begin where you are and build from there.

If you’re ready to get stronger, move better, and feel more empowered, let’s get started!

We’re hiring. GYM41 is looking for a Group Fitness Instructor. See the posting on Indeed.
