Hello,

I’m Jonathan Dumer, and I’m here to help you feel stronger, move better, and live fully.

At Silver Fox Health & Fitness, I provide personalized fitness training designed specifically for active adults, right where you are. Whether your goal is to improve balance, build strength, increase mobility, recover from an injury, manage chronic pain, or navigate rehabilitation, I’ll create a plan tailored just for you.

What I love most is working alongside people and seeing what really works in real life. Every session is an opportunity to learn together, how you respond, what motivates you, and how we can make fitness both effective and enjoyable. That shared experience creates a community of real life results, and we have fun doing it. I’ll help you stay active, independent, and energized for the things that matter most, family, travel, and everyday life. Let’s create a healthier, more vibrant version of you, starting today.

67 to 94. Thank you for watching.

A Life full Fitness

Originally from Wales, I came to Canada in 1974, and my love of movement started early. From childhood judo and high school soccer to boxing, running, and a life of weight training, staying active has always been a part of who I am.

After six years with the Ontario Provincial Police (O.P.P.), where I received the O.P.P. Fitness Award five times, I realized my true passion was helping people improve their health and wellness. While I valued my time in law enforcement, I wanted to make a more personal impact by supporting others in living active, vibrant lives.

That calling led me into the fitness industry, first in sales, then management, and eventually owning my own gym. Today, at Silver Fox Health & Fitness, I work with Active Agers to help them move better, build strength, and feel more confident in their everyday lives.

I continue to grow in my field so I can provide the best guidance possible. My courses and certifications include:

• Y.M.C.A. – Certified Personal Trainer
• CPAFLA – Certified Fitness Appraiser
• C.P.T.N. – Personal Training Courses
• CanFitPro – Active Aging Movement Specialist
• F.E.O – Training Older Adults Level 1 & 2

With 27 years of experience and over 10,000 clients, I’ve seen first-hand how small, consistent steps can make a huge difference. I design programs that are safe, effective, and tailored to each individual, helping my clients stay independent, active, and energized for the things they love—family, travel, hobbies, and everyday life.

Let’s work together to keep you moving, feeling strong, and enjoying life to the fullest.
