What makes a great coach?

The ability to assess and understand each individual’s fitness goals and any related issues they may have, possess expert knowledge on how to effectively address these issues and achieve those goals, and create a supportive and motivational environment that encourages progress and success.

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.

Having always been tantalised by watching gymnastics competitions, I never had the opportunity of trying it out as a child and later in life I felt I was “too old” and intimidated by it. In 2013 I saw a friend posting videos online of him doing CrossFit and it looked fun so I found a box near work and started going. Soon I was hooked! I suddenly enjoyed working out and the community spirit really helped. For the first time ever, I felt comfortable in a gym and looking forward to going!
Following my interest in CrossFit and learning more about it, I started interning to become a coach in 2014 and later on I took my L1 course, both in London. The more I coached, the more I enjoyed it. It’s very rewarding to connect with your members and see their progress hand in hand, so I have been coaching part-time in every country I have lived in: UK, Spain and Malaysia. And now I’m very happy to be doing my best to convey this expertise built through the years to the LIFEFIT MINAMI family!

I’m relatively new to CrossFit, and pretty new to coaching. I have, however, been training for and playing sports most of my life. From rugby to athletics, triathlon, rock climbing, hockey, marathon running and even cricket, I’ve played a lot of sports.
After a bad run of injuries from marathon training in 2016 I decided to give CrossFit a try instead. Needless to say I loved doing CrossFit, and have been improving ever since. One part of CrossFit that I’ve really enjoyed is the community here. As I learned more and more about CrossFit, improved my mobility and got fitter and stronger, I started to want to help others do the same. That’s when I decided I wanted to become a coach.
I did my Level 1 in January 2018 and started coaching at LIFEFIT MINAMI in May 2018. I’m enjoying the challenges of coaching, especially in a multi-language environment! I’m training not only to become better, but a more knowledgeable coach as well.
