After 40 Fitness was created with the sole intent of measurably improving the physical and mental health of our clients through individualized personal training, nutrition and lifestyle coaching in a safe, fun, and supportive environment. Exceptional customer service, compassion, and continuing education are at the core of our business.

Our Philosophy
We believe in a balanced view of your overall health and not just what the scale currently says. Our certified coaches are well versed in various fitness and nutrition modalities, and together we will design a safe and effective plan targeting both your short and long-term goals. We welcome the involvement of your doctor or other health practitioners.
We understand that change is seldom easy… we are committed to supporting our clients both in and out of the gym.
How We’re Different
We employ a client-centered approach to each of our services, every day. It’s not about us. No egos, no intimidation, no up-selling, no shame. Our primary objective is to help you achieve the long-term health and fitness results YOU are looking for in a relatable way.
What They’re Saying
“I highly recommend this trainer. I worked with Brian for a year strengthening my core, improving my endurance, flexibility and overall muscular strength. My back has always been an issue for me but not anymore!”
“I have been a client of Brian’s for over a year and am so grateful for the time I have spent with him to strengthen my body. He is a motivator who believes passionately in the power of exercise for our minds, body and spirit!”
“I had never worked out in my life. I am much firmer and stronger now than when I first started, which is exactly what I wanted. I am so glad to be working with Brian and would highly recommend him to anyone!”
“Everyone should have a personal trainer like Brian. On days I didn’t feel like going to the gym, knowing he would be there for me motivated me. If you’re looking for a trainer that will personally care about you, Brian is your guy!”
Meet the Founder

Brian Sirois
Founder / Lead Trainer
Brian is the epitome of “it’s never too late” to get fit. Once a high level business executive, Brian was told by doctors he would need medications to counteract his stressful lifestyle. Brian turned instead to exercise and nutrition to lose weight and improve his quality of life. Today, he is a competitive endurance and cross-training athlete, having completed over 50 races from 5ks to full marathons. Combining his lifelong passion for helping others with his passion for fitness, Brian is deeply committed to helping his clients achieve their health and wellness potential.
