Jonathan Mastin-32_edited.jpg

Jonathan Mastin is a master of his craft. As an elite certified coach who holds certifications from the National Academy of Sports Medicine (NASM) as a Certified Personal Trainer (CPT), Corrective Exercise Specialist (CES), and Certified Nutrition Coach (CNC), he provides exceptional one-on-one support.

His journey into physical fitness began at a young age as he explored dance, figure skating, tennis, track & field, and pilates, to mention a few of his favorites. As a former competitive swimmer, he competed against Olympic swimmers Michael Phelps, Aaron Pearsall, and Brendan Hansen back in 2005. Jonathan’s dedication to fitness and health is unwavering.

Jonathan’s integrated coaching style adopts a holistic approach to training, considering all aspects of health and wellness. He believes that training is most effective when mind, body, and spirit are all working in sync. That has been his focal point while building fitness programs for his clients since 2008.

His clientele is diverse, ranging from athletes to individuals in post-rehabilitation and those managing medical conditions, such as diabetes, ALS, nerve damage, and cancer. His ability to work effectively with these clients stems from his personal experience. Diagnosed with epilepsy in 2010, Jonathan underwent a journey of over 40 different medications before having a Responsive Neurostimulator (RNS) implanted in his brain in 2023 to manage his seizures. Now he wants to show others how an effective fitness program can be key to improving quality of life.

Despite his disability, Jonathan has never allowed epilepsy to dictate his life. He is a firm believer in enhancing one’s lifestyle through a combination of exercise, recovery, nutrition, and attitude. And that’s the belief he instills in his clients and practices in his daily life.

Outside of coaching and exercising, Jonathan enjoys traveling with his wife, a good cup of coffee and quality time with his dog Cocoa.

Testimonials

Don’t take Jonathan’s word for it… hear what his clients have to say about him.

The workout that I needed.

I thoroughly enjoyed the workouts Jonathan designed for me. I was getting a full-body workout while incorporating a mixture of weight exercises and cardio, which was exactly what I needed. When lifting weights in the past, I never even built up a sweat; but with the high-intensity exercise circuits Jonathan created for me, I was getting a great cardio routine that also helped me build muscle. Jonathan listened to my goals, and created a program that incorporated low weights and high repetitions. I saw the results almost immediately. I definitely recommend Mastin Fitness, as the focus is providing individual-based programs to help you achieve your goals, whatever they may be.

Jonathan’s knowledge is unbeatable.

Jonathan has a deep understanding of the human body, and how it’s intrinsically related to our minds. He also has a knack for being in tune with a client’s limitation, be it due to an injury or lack of experience in the gym. He managed to work around my spinal injury and helped me reduce the pain caused by it. Jonathan created a program that built up the muscles surrounding my spine, and I am grateful for his guidance and knowledge. I would 100% recommend him to anyone looking for a highly skilled and knowledgeable trainer.
- Jacquelyn B.

Experience was great, and so were the results.

Jonathan was my coach for over a year and a half, training me twice a week, and I can’t recommend him enough. A skilled coach, extremely knowledgeable, reliable and capable. He knew exactly how to motivate me and keep my private sessions interesting and challenging. His programs were rewarding, and I saw the results. I encourage anyone interested in improving their health to try Mastin Fitness, you won’t regret it!

Top-notch training sessions.

When our 10 year old daughter developed knee pain and swelling, her doctor diagnosed her with patellofemoral syndrome, and prescribed strengthening exercises. She made slow progress until Jonathan offered to supplement her regiment with weekly physical therapy-like sessions. He was very patient, and helped our daughter work on the exercises prescribed by her doctors. She enjoyed her sessions, and quickly regained full knee-function without pain. Jonathan was a pleasure to work with, he is a seasoned trainer with a caring and calm demeanor. We recommend him highly and without reservation.
- Susan and David W.

5-star programs, 10-star trainer.

Working out while having Jonathan as my trainer was more than just an hour-long exercise session. Each time we met, I left my private training workout with more knowledge about how to improve my lifestyle and incorporate better nutrition than I had anticipated. Jonathan helped me develop habits I will carry with me, and he taught me how to enjoy most of them too. His expertise is superb, and he is remarkably engaging. I appreciated how he was willing to adapt his approach based on my goals, and how he guided me to apply some key fitness concepts into my day-to-day life. If you are looking to improve your lifestyle for the better, Jonathan is your coach, look no further.
