This was the million dollar question

“What’s the worst that could happen?”

That’s what our physio Justin said to me as we figured out what we’d do with his 20 hours of work way back in July of 2020.

For most of us, any mention of 2020 will send shivers down our spines.

But in this case, luck had been kind to both of us. 

Just two weeks prior to the first COVID lockdown where literally the whole world stopped, Justin had taken a permanent, part-time shift on a Saturday morning to provide some extra physio coverage.

There was no reason he needed to do this, but he wanted to help me out because I was in a pickle.

By the good graces of whomever/whatever you think is looking over us, this stroke of good fortune meant that he was eligible for Job Keeper – which guaranteed him 20 hours per week working for AA.

Instead of twiddling his thumbs, Justin, Lachy and our other physio at the time, Alan, spent the compulsory 3 months of gym closures putting together the most complete and ambitious ACL rehab framework that we’d ever heard of.

Every set & every rep.

Both on the gym and on the pitch.

Meticulously laid out in macro, meso and micro phases.

This ACL program accounted for everything you could possibly imagine.

Graft type… existing training age… sport… non-operative… brace-protocol…

No stone was left unturned.

By the time it was done — some 500 hours later — it was seriously epic.

So when we were allowed to reopen 3 months later, we were able to attract 5 or so ACL athletes into our training schedule, which we called ‘Rehab Gym.’

I then put my business brain together to optimise the business model and ramp up marketing for it, and before long, some 6 months later, the 5 rehab athletes had become 50, and Justin had a full-time job.

And as I write this – exactly two and a half years later – we’ve now got over 120 athletes in our rehab program where great athlete results come as standard.

And while we’d never be so bold to say it, others have called our program:

“The Gold Standard.”

One of the convenient, yet unexpected bonuses of producing a rehab model like ours is that it completely transformed our whole business.

When Justin asked that simple question, we would ultimately take a 600k turnover gym and gross over 3.5 million some 2.5 years later.

And while there was definitely risk involved in rolling it out – the worst-case scenario ended up being something most of us would only ever dream of.

Looking back… It’s crazy to think that one decision like a systematic framework for rehabbing the ACL… could play such a pivotal role in our success.

And if we’re entirely honest… we still sometimes pinch ourselves just to make sure it’s all real.

Now, with our rehab system humming like clockwork, we can now pay it forward, so you can achieve what has been so life-changing for us.

And given the amount of people that either DM us or Juzzy on how to do it, we know there is a lot of demand to get your hands on the system, straight from the horse’s mouth.

But here’s the deal.

Our 10-week ACL Mentorship is NOT for everyone.

– It’s not for the practitioner who wants to rub old people’s backs day in and day out, that might be your jam but it definitely ain’t ours.

– It’s not for the practitioner who thoroughly enjoys seeing 70 patients a week, having to do clinical notes on the weekend, and wants to be on a merry-go-round that never ends.

– And, it’s not for the practitioner who doesn’t want to have a stampede of athletes ready and waiting to work with you week in, week out, for 9 months at a time who will always be willing to pay.

Because what the ACL Mentorship WILL do is completely transform your business.

1. You’ll have more athletes than you’ll know what to do with (which means hiring more staff and expanding your bottom line).

2. You’ll have more fun (which means a better work culture).

3. And you’ll have more people shouting your name from the rooftops (because you’ll actually blow people’s expectations out of the water).

Now, of course, that kind of success is not for everyone.

In fact, it’s not for the vast majority of physios, practice owners, or S&C coaches.

It’s only for the people who know that there is a better model out there…

… But don’t know how to implement it seamlessly, effortlessly, and effectively…

The next ACL Mentorship intake starts in May.

And for context,  we sold out the last intake, and the two intakes before that, too.

And without doing any marketing, there are already 4/10 spots snapped up by 4 keen-bean practitioners who have been banging on our door to start.

So we thought that before time runs out (since we’re only running one a year from here on out), we’d give you the chance to be one of six more practice owners or serious practitioners who are just one rehab system away from completely transforming their bottom line, staff culture, and clientelle they work with.

Because keep in mind, this system only really works with athletes.

Lachlan Wilmot



  • Bachelors of Exercise and Sport Science
  • Honors in Rate of Force Development in Team Sport Athletes

Lachlan began his professional sports coaching career as the second ever employee at the GWS Giants in 2010-11 season prior to entering the AFL in 2012. Over 7 seasons, Lachlan grew a team of talented young men into back-to-back preliminary finals contenders. As the head of strength and power, his role was to turn teenagers into physically dominant men, developing their strength, power, speed and most importantly, their resistance to injury.

In 2018, Lachlan’s success afforded him the opportunity to shift codes, having been offered the role of High Performance Manager for the NRL’s Parramatta Eels.

In as little as one rebuild season, he had taken the wooden spooners of 2018 to the finals in 2019, where they inflicted the greatest defeat of the Brisbane Broncos in NRL history. By 2019, it was time for Lachlan to go ‘all-in’ on his other baby, Athletes Authority.

Now, Lachlan leads the performance program, designing the programs for all the athletes here. He works closely with the sports medicine team, just like he did in pro sport, to help athletes achieve more and reach new heights with their athletic careers.

Karl Goodman


Karl began his career in coaching as a Personal Trainer back in 2007. After competing for NSW as a Baseballer, and then competing at an elite standard as a cyclist throughout university,  Karl received the opportunity to work with Gordon Rugby in the Shute Shield competition. From there, he found a way to marry his passion in sports and competition with coaching; selling his investment property to start Athletes Authority in early 2016.

Starting from humble beginnings, the facility vision was taken to another level when Lachlan and Karl partnered up in 2017 and Athletes Authority was incorporated. It was no longer just a gym training athletes; Athletes Authority was committed to becoming a brand athletes worldwide could rely on for quality coaching, advice and service.
