What makes a great coach?

Sean McAuliffe 🇦🇺



Hi, my name is Sean McAuliffe, and I am the founder of LIFEFIT MINAMI. I have always been involved in fitness, starting with a variety of sports such as football, lacrosse, and triathlons, as well as traditional weight training in gyms. However, it wasn’t until I discovered functional training and CrossFit that I truly found my passion in overall health and fitness.

As a qualified motor mechanic for Mercedes-Benz for 7 years and a mechanical fitter for 7 years in remote locations in the Australian mining industry, I have learned to adapt to various physical and environmental demands. It was a colleague who introduced me to CrossFit, and I immediately fell in love with the diversity of workouts, competitive spirit, and camaraderie it offered.

While working away from home in the mining industry, I had to make use of the gym facilities available and quickly shifted my training style to follow CrossFit principles. This led me to achieve the results I had been seeking for a long time. I even trained at X45 CrossFit Kota Kinabalu, Malaysia for a few months to gain more knowledge and skills in CrossFit.

I then moved to Osaka and opened LifeFit Minami 8+ years ago. I am continuously learning by attending CrossFit level 1 and 2 courses as well as self-researching. My focus now is to provide a training method that is low-impact, with full range of motion and functional, that can be accessed by people of all fitness levels.

My goal is to help people achieve their goals in weight loss, strength, and live a pain-free life.




During my upbringing, I was always engaged in physically demanding activities such as hard labor and a wide range of sports including soccer and kickboxing. As a fighter, I recognize the importance of cardiovascular fitness as well as strength and mobility. Based on advice from friends and coaches, I decided to give CrossFit a try, and my interest grew to the point where I became a coach myself with a goal of improving my own abilities.

Despite being new to this realm, having experience as a kickboxing coach has given me a deep enjoyment in helping and guiding others to become better at what they do. Witnessing individuals transform into a more positive version of themselves is truly rewarding. However, to excel in my coaching role, I am committed to furthering my knowledge in fitness. This includes pursuing personal training and nutrition certifications.

Moving forward, my plan is to be a coach who is always there to support others while also pushing them beyond their limits. If you ever need advice or guidance, you can always count on finding me!


Matt Cartwright 🇦🇺



Hello, my name is Matt, and I have been a coach at LifeFit Minami for the past five years. Ever since I was young, I have been actively involved in sports, ranging from rugby to rock climbing, and from little athletics at the age of 8 to marathon running here in Japan.

However, after a string of injuries from marathon training in 2016, I decided to give CrossFit a try. It was a decision that I have never regretted, as I found the group setting to be both motivating and encouraging. Not only did I become fitter, stronger, and more mobile, but I also developed a sense of camaraderie with others.

As I continued to improve, I felt inspired to help others achieve their goals as well. This led me to become a coach, where my philosophy is to create an inclusive and supportive environment that helps everyone reach their potential. I am committed to continuously learning and improving my coaching skills by drawing from my own experience and incorporating knowledge from various sources.

I strive to apply everything that I learn to help each member improve in whatever area of their life they are aiming for. I believe that with hard work, dedication, and a positive attitude, anyone can achieve their fitness goals.
