Clients Truly Benefit From Our Programs.

See the testimonials for yourself...

“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.”

“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.”
