We've worked with

Clint Gutherson

“Love working with Lachie at Athletes Authority, a coach that values an athlete’s feedback and implements it into their training program. Rare to have a coach with so much knowledge yet always looking to improve. Knowing every athlete was an individual and doing his best to come up with a plan to suit. The best always look to get better.”

Dylan Shiel

“It is rare to be coached by someone who has an abundance of knowledge but also the drive to learn. He listens to the athlete and works with them to get the best out of themselves. I was fortunate to work with Lachie for 5+ years, he is the reason I am the athlete in strength and conditioning I am today.”

Zac Williams

“Working with Lachie was a great benefit to myself, as I didn’t know much about strength and conditioning as an 18 year old. He made it simple and clear in what I needed to do over the few years to be able to play AFL at the top level. It was amazing to have a coach take the time and effort to prepare & make me the best player I could be. Lachie has set me up to be the player I am today.”

Our Philosophy

While An Athlete's Goals May Change, The Pursuit Of Performance Never Ends.

While an athlete’s goals may change from season to season, there are two things that never will.
The first constant is that every athlete wants to hold themselves to a higher standard. They want to raise the bar, push the boundaries and reach a level of performance they haven’t had before. There is always the belief that you can reach higher and achieve more.
The second is that they want to win. No athletes make the sacrifices they do so that they can turn up and lose. It’s in every elite athlete’s DNA. The desire to win is like oxygen for the soul. An athlete can’t live without it.
The only way to achieve this level of success is to develop a GamePlan unique to the individual. This GamePlan follows a simple philosophy that we turned into a training system:

Minimise The Downside (Injury) While Pursuing The Upside (Performance).

Whether you’re an aspiring amateur or Australian Olympian, this system helps athletes at any point in their career reach a higher level of performance. With our system, you will develop a bulletproof body and mindset that is ready to succeed.
Our system combines in-person coaching with virtual and mobile support so that every athlete who wants more, can achieve more.
With our performance and rehabilitation programs, you’ll always have expert guidance within reach.
