Hey, I’m Jai. The Founder of Square One Fitness. And this is the story of how Square One Fitness started, and became the gym that it is today.


After a 13 year career in the I.T profession, I realised that it wasn’t my passion.

Doing something I wasn’t enjoying everyday really brought down my energy, my health,

And my happiness. Until the night I had a cardiac arrest, and everything changed for me.


I’d had a late night celebrating a good friends birthday. Then I was up early the next morning

For a basketball training session with my team. My energy was low, my body was under stress from a hang-over, and I was really pushing myself on the basketball court. This triggered a response in my heart called Wolf-Parkenson-White-Syndrome. Something I was likely born with, but was never recognised/noticed. An additional electrical pulse in my heart.


The extra stress triggered the pulse, which created an irregular heart beat, which led to a coma, then cardiac arrest. Thankfully by the time this all happened I had checked myself into the hospital where they were able to save my life.


The time spent in hospital was quite an eye opener for me. I noticed all the middle aged men with clogged arteries filling the cardiac wards waiting for bypass surgery.

I realised there are too many of us living unhealthy, and winding up in hospital dealing with heart surgeries. It’s the last place you want to be.


In that moment, I knew I could help people avoid this fateful future. I knew that with regular exercise and a healthy diet and lifestyle, we can all avoid sickness and premature ageing.


That’s when the idea came to me to have a career and life change and become a personal trainer, and be completely independent, and run my own business.

I’d always wanted to own a business, but I knew that it had to be a business that I would be excited to be involved in. Fitness and sport have been my favourite things my entire life, so it made sense to take the leap.


It was a tough decision giving up a cushy, high income career for the complete unknown,

And starting from zero in an industry where I have no experience. But I learnt a great lesson from the cardiac arrest I experienced, and that was to make the most of my life. Coming so close to losing my life made me realise how precious life really is.


So I signed up to night classes at the Australian Institute of Fitness to get my cert 3 & 4 in Fitness while working my I.T job by day. By the time I had all my required qualifications, I’d already set up my website, and spread the word that I was the new trainer in town!


With 3 months of annual leave and long service built up from my 13 year career, I was able to use this as my buffer while I got my PT business started.

By the 3rd month in I had 40 clients that I was training outdoors in parks and homes in the inner west area. This was enough for me to quit my job and pursue my PT career 100%.


After about a year of working with clients 1 on 1, I realised that my fitness education wasn’t helping me with the psychological, emotional, and relationship issues my clients were suffering from. So knowing I needed more tools to help my clients, I completed a diploma in Life Coaching. Not only did this help my clients, it also helped me and my business.


I started hiring contractor PT’s and growing my client base, sharing the load of work with other trainers. During that time I met Kate, who shortly after us meeting in 2012, became my girlfriend, then a contractor PT at SQ1, and today my wife, and co-owner of SQ1 Fitness.


In 2013, Kate’s brother Chris joined the team, and by 2014 we opened our own private studio/gym and move away from the outdoor training business model that came with a lot of restrictions and frustrations.


We found the perfect place on Silverwater road that was just the right size for us.

Since then we’ve upgraded our gym multiple times over to what it is today, and we’ve also grown our team, and our members.


Today, in our private warehouse gym in Silverwater we run 15 group classes per week, and over 150 Personal Training sessions per week between Monday and Saturday.


Our philosophy to training is Functional. Simple. Consistent.

And our approach to nutrition is Holistic. Flexible. Natural.


We work mostly with regular people who you wouldn’t categorize as “FIT”. And it’s our goal to get them to FIT and healthy.


We have a great family community vibe in our gym, and are kiddy friendly.

We love all of our members, and have been helping the community with health and fitness for going on 9 years now. 

Each year, we work together to make food donations to our supported charity, FoodBank, t0 help feed the hungry, as well as catch up for group events including bush walks, fun runs and even sometimes the pub for a beer or two. 😉

The future of Square One Fitness is to get better at what we do every day, and continue to grow our member base, so we can provide positive impact for our community with their health and fitness for years to come. 


If you’d like to be a part of the SQ1 Family, call me directly to chat about getting started. I’d love to help you reach your personal health and fitness goals, and welcome you to the SQ1 Fam!
