Exercise has always been a way of life for me. It’s in everything I do.

Ajay Joshi – Group Fitness Manager / Personal Trainer

Hi, I’m Ajay, I’m a BIG believer in achieving anything, whatever size, gender or age you are! I will be increasing your confidence and enhancing your mental capacity to help you to reach your goals, not only this, I want to show the world what you’re made of, how amazing you are! I love being creative and enjoy especially training endurance, high intensity interval training, Circuit training and team-based training.

I grew up in Sydney loving my sport and played club cricket and moved to Canberra when I was 17 in 2011 to study a design course at University of Canberra. This was the start of another stage of my journey. In 2011, started my first job as a casual employee at the AIS Shop, and still working there; this is where my confidence has been developed from, and nowadays I see what’s developing in the industry. Through out these years, I was lucky enough to live at the Australian Institute of Sport for 4 years. This has enhanced my knowledge in nutrition and of an elite athlete’s lifestyle.

2012, was the biggest year for me mentally, I was the driver of a rolled car trying to escape to the coast for the weekend with my mate on board. This was the worst I had ever felt in my life. Throughout the time I had been living in Canberra before the car crash, I had unhealthily gained 12 Kg  within 16 months, I had never walked foot into a gym or outdoor fitness session in my life and also didn’t play a sport throughout this time.  From here, I had a hard look in the mirror and made a goal. This was to play AFL for a local club in 2013, thus I finally stepped foot into a gym and group classes. I was at 82kg and hit 70Kg in 6 months, and thought of trying a new sport instead (hockey), which I successfully did and finally started playing club AFL in 2015 and still am.

The best step I had ever made in my life was to join a gym/ group fitness sessions and would love someone who has never stepped foot to do the same and experience the feeling what fitness goers are feeling and what it’s about.

Glenn Johnston – Personal Training Manager / Group Class Instructor

Hi there, my name is Glenn and I believe that there is a stronger version inside all of us. I have had my own weight loss achievements and journey to share. At a point in my life I weighed approximately 130kgs and then had an epiphany, I needed to change my lifestyle and get healthy again, just like when I like when I was a teenager. From there I enlisted a coach and changed my life. I was lucky enough to lose 30 kg in a short time, through hard work, sweat and tears.

With the tools and experience I have to offer, you will be happy to trust me as the trainer to share your weight loss  or fitness journey with.

Tim Hazell – Personal Trainer / Group Class Instructor

Hi, I’m Tim, Personal trainer at Define Fitness. I am a young trainer with a passion for helping people of all ages achieve their goals.

I developed my interest for fitness through a strong involvement in a number of sports around the Canberra region including cricket and soccer. This is where I first learnt the need for fitness and exercise and also the enjoyment it can bring physically and mentally. My first exercise programs I was instructed to do was from these sporting teams and that was where it all began for me. While I have always had the luxury of keeping fit through playing sport, I also have discovered that further exercise doesn’t do any harm and quite often can leave you feeling refreshed.

I firmly believe exercise is as much about physical strength as it is mental strength and I feel as much enjoyment from seeing physical progress as I do seeing the client in a happy state of mind.

Upon completion of year 12, I tried my hand at different sports including Thai boxing where I achieved a grade of level 4. Many group classes and recently I completed a term of salsa dancing. I enjoy variety when it comes to my personal fitness.
