Meet Me, Armstrong Lazenby
I’m an Australian athlete renowned for my accomplishments in short track speed skating and my appearance on Australian Ninja Warrior. As a key team member of Fitness Image Personal Training, Melbourne’s largest multi-site fitness company, I bring elite athletic experience to help you achieve your fitness goals.
I specialize in helping clients achieve amazing weight loss transformations through our signature “42 Day Lean Body Reset” program. I’m so confident in my approach that I guarantee you’ll lose 5kg in just 42 days or receive a full refund.
Stop struggling with gyms, Keto, apps, and always ending up where you started
2
Avoid comfort foods to cope with life
3
Reverse feeling afraid to fail again and end up wasting your time and effort
4
Eliminate the ‘what’s the point’ mindset if you’re not perfect
5
Avoid feeling frustrated when you do great for seven days, then experience setbacks and feel worse than before
I designed my 42 Day Lean Body Reset to put these problems to rest. I’ve experienced these challenges myself as an athlete, and I know that one-on-one support and professional guidance are what you need to take control of your health and body.
My Science-Based 3-Part Method
Through my years of athletic training, I’ve learned that losing weight is like lighting a fire. You need 3 things, and without them, the fire goes out. In my experience, most people struggle because they’re missing at least one of these essential elements:
#1: Personalized Nutrition
I create a custom eating plan built for your body and preferences, not generic diets that lead to frustration. I’ve used these principles in my own athletic career.
#2: Effective Training
I’ll guide you through targeted exercise that maximizes your results in minimal time through my proven Muscle Confusion method that I learned from professional coaching.
#3: Ongoing Support
I provide consistent accountability and guidance that keeps you motivated even when life gets in the way – something I’ve found essential in my own fitness journey.
My 42 Day Lean Body Reset combines all three elements into one powerful system that guarantees your results. I’ve seen firsthand that it’s not about another diet or workout plan—it’s about solving the fundamental problem of sustainable weight loss once and for all.
My Athletic Career
My Ninja Warrior Experience
2018 was an exciting year as I took my athletic ability to a brand new challenge in Australian Ninja Warrior. Airing on July 8, 2018, I was among the competitors attempting to scale a tough obstacle course that pushed my limits in new ways.
Commentator Notes About Me
“At 95 kilos, he’s a big boy with plenty of leg strength from his skating roots.”
During my run, I faced challenges with the course, ultimately being eliminated on the punching bag obstacle. This experience taught me valuable lessons about adapting to different physical challenges. I’ve since incorporated obstacle-based fitness into my client programs, helping them develop well-rounded functional strength.
My Speed Skating Journey
I became known as a talented short track speed skater representing Australia in international races. As a member of the Australian Speed Skating squad, I entered many major events and played a key role for the Olympic Southern Flyers Senior open club relay team when we won the championship in 2012.
My Scholarships & Recognition
I received a scholarship from the Victorian Institute of Sport
I trained with the Australian Institute of Sport
I was recognized by the International Skating Union
I was supported by the Olympic Winter Institute of Sport
I was named 2013 Australian Junior Athlete of the Year

“I was exercising regularly before starting but still lost 6.5kgs in 6 weeks with Armstrong. His dietary recommendations were easy to follow and adhere to. Very satisfied with the investment.”
– Brett, Fitness Image Client
You will either lose 5kg or get a full refund. The only thing that won’t help you is to do nothing.
The next 42 days are going to pass anyway. The question is – do you want to be:
5kg lighter and feeling confident
Finally free from the frustration of failed attempts
