How To Get Clients Results That 

Change Their Life (And Yours)


Your career, reputation, and earning power as a coach revolves around one thing: the results you deliver to clients


Here’s how you do that better.



Your mission is simple:

Get as many client hours that you realistically can.

It’s the most productive use of your time. Working with clients earns you money, builds your reputation, can provide great “proof” for marketing yourself, and is often the most satisfying time in your week.

(Of course, the coronavirus has changed things, and I’ll get to that in a moment.)

For the most part, you’re already delivering solid results for your clients. You help them trim down, bulk up, build athletic performance or put more weight on the bar.

But since you’re reading this, it’s likely you want to do even more.

Greater results mean greater satisfaction for both your clients and yourself.

With that comes the growing reputation, the growing number of clients who come knocking, and the growing rates you can charge.

You also realise that, without knowing the principles that govern how our bodies work, how they react to stimulus, or how they differ, you hit a hard limit. To train clients to reach the highest levels of fitness and performance, you need to develop the capabilities to fully support them.

To learn the “1%ers” that the average gym rat wouldn’t bother with, or concepts that add another couple of kilos to a lift or shave a few seconds off a time.

That’s what you’ll find here.

The Science of Fitness: The Transformative Approach For Training Health, Fitness and Performance


The Science of Fitness is designed to give you a deep, fundamental understanding of how our bodies work in the context of health, fitness and high performance.

And there’s one reason above all that this gives you an incomparable edge over any other coach who doesn’t know the body like you will do.

The human body is the one constant we work with. Month after month, year after year.

You’ve seen it yourself. The technology we use is changing. Fads of the month come and go (and will always be a favourite of coaches who don’t know any better). Society and what people expect move with the times.

You recognise that adapting to the differences between two bodies — the biomechanics, health complications, or nutritional needs — involves more than just tweaking a meal plan or adjusting exercises to suit.

The principles in this program transformed how I worked with clients. They were, and still are today, the cornerstone of the success I had as a coach, then as a “coach of coaches”. And I have little doubt that if you apply what you learn here, you’ll unlock more success with your clients and career or business as well.

Note: The Science of Fitness examines some advanced topics that new coaches may struggle with. If you’re still finding your feet in the coaching business, you may want to consider whether this is for you right now.

However, if you’re willing to put in the study (as you’ll see down the page, we start with the basics of biology before moving on to more in-depth, actionable subjects), you’ll find this program can accelerate your progression into the ranks of first-class coaching.

Become a stand-out authority in a crowded industry
Develop a “magic touch” that lets you get results with every client you work with
Increase your earning potential: your rates climb as your expertise grows
Lay the groundwork for a long and successful career as a go-to trainer

Let’s Talk About The Elephant In The Room...



The pandemic and the resulting lockdowns have left our fitness industry in tatters.

As a result, businesses have done their best to stem the bleeding, reducing costs and downsizing until things return to normal.

(Though it’s entirely possible that we never get back to how they were.)

That’s only half the story, though. Others have adapted or looked for opportunities as the new landscape forms. The “every man and his dog” shift to online fitness is an obvious example, but that’s just one relevant to most of us.

The point is that sitting on your hands and waiting for normal to return is perhaps the worst thing you can do.

Take what you’re reading right now: I’m launching a large, intensive program in the aftermath of the lockdowns. That’s because there’s an audience ready to grow themselves and their careers, and won’t let circumstances dictate when or how that happens (within reason, of course).

I don’t say any of this to nudge or guilt you into this program. There are plenty of things you can do to grow your expertise and career, and they might make more sense right now. But if you’re fortunate enough that you can look at deepening the core skills that make you a top trainer, then The Science of Fitness is well worth considering.

Why I Built The Science Of Fitness


If you’re reading this, you’re probably familiar with my story.

How I got into lifting in the first place (recovering from a rugby injury).

How I made a mess of those first few years (mashing together all kinds of info I “researched” from blogs).

And how I went through university to really learn more about how the body and mind work.

While I did find a solid understanding at uni, so much of what made me a successful, knowledgeable coach was learned AFTER these early years.

That’s because the findings and “eureka” moments that have the greatest impact aren’t often found in blogs or on YouTube (shocking, I know). Even the degree I studied had a mountain of unnecessary material for anyone wanting to focus on improving or maximising health and fitness.

Since those early days, I’ve spent years conducting my own research. Rummaging through paper after paper to extract nuggets of wisdom. Taking careful notes and cross-checking against other references. Testing these out in the field to see which held water. And then turning those notes into lessons and lectures that were the foundation to the results I got working with clients of all shapes, sizes, issues, and goals.

It was the combination of academic theory with the field-tested finds that helped me achieve things with clients that few other trainers could match.

But I didn’t build this program for my benefit. (I organise my personal notes in a way that works for me. It would probably just confuse anyone else who saw it.)

There’s a surging demand for advanced learning in the fitness field. I’ve had hundreds of people ask for a program like this over the years. I put it off for a long while: this is an enormous field of study, and to bring it together so it’s accessible and valuable to coaches was a huge effort.

However, I love showing what’s possible when you delve deeper into the body, and wanted to share it with others in a similar way to the 1-on-1 coach mentoring that I used to do.

So, the Science of Fitness was born.

Are There Other Options?


The other reason I’ve built The Science of Fitness is that there’s simply nowhere else coaches can find this kind of knowledge. There’s no shortage of education out there, but most of it isn’t right for material this advanced...

Weekend Seminars are too short to go into much depth beyond one or two subjects. A few days after it’s over, you’ll have forgotten 80% of what was discussed, not to mention the inconvenience of a fixed date.

University Study means you’ll spend at least three years and over $20,000 learning some (but not all) of the concepts you’ll find here. You’ll also end up learning a lot of irrelevant ideas that won’t do anything to make you a better PT or coach.

Certifications are great for shallow subjects, ticking the “qualified” box, and not much else. Plus, some can cost just as much (if not more) than the Science of Fitness.

Luke's passion and dedication to his craft allows him to bring very complex topics right to the level of the application to the end user.

His unwavering poise and unmatched intellect allow him to operate with a level of integrity not often seen in the fitness industry.

His physiology courses are raising the industry standard for education. If you are looking to upskill as a PT or clinician, I can't recommend Luke enough.


Miami, USA

You get a lot of info and there is a lot of content in each video. Everything is explained deeply but in a way non-professionals can understand. 


Melbourne, Australia

Very helpful in order to apply methods developed from science based information that will eliminate having to sift through the industry weeds.


Canberra, Australia

Love this. No bro science - Actual science. The level the sessions are pitched at is perfect and Luke knows his stuff. 




The Science of Fitness: Your Program Of Study

As far as I know, this is the most complete course on fitness, health, and the human body you’ll find outside of a multi-year university course.

Here’s a list of what you’ll learn and apply over the next few months.


Learning vs Performance
Learning how to learn is the first step to wringing 100% out of the rest of the program. You’ll also explore the difference between short-term learning and long-term retention.

Brush up on fundamental statistics to help you understand how to read scientific research better and demystify how research papers are interpreted.

Biology is based on chemistry, so you’ll learn some broad principles of chemistry as a foundation for the more advanced (and interesting) topics.

Biomechanics is key to knowing how to individualise exercise. If you haven’t looked into biomechanics before, this will change how you look at exercise selection forever.

Training Principles
These eight lectures give an overview of general training principles you can apply right now to your programs. We explore some of these in more depth later, but the goal here is to get you up to speed as quickly as possible.

Nutrition Principles
Similar to the training principles, the goal is to give you an info-packed overview on how to set up a nutrition plan. We won’t spend hours looking at every little nuance now, but focus on giving you everything you need to start getting results immediately.

Physiology Foundations

This series of lectures give you the “backbone” of understanding into the physiology that underlies how the human body works. The topics covered here are what you’d expect to find in an Exercise Physiology degree, but streamlined and made relevant for coaches.

These will allow you to brush up on specific topics prior to the live lectures. For example, the Muscle Overview videos support the live lectures on Mechanisms of Muscle Hypertrophy.


Advanced Topics

Here’s even more of what I’ve got planned for you:

Non-Exercise Activity Thermogenesis
NEAT is the most variable factor when it comes to the “energy out” part of the energy balance equation. If you get this right, you’ll look like a wizard to clients. There's just one problem, though – most people have no idea how deep NEAT goes. This lecture gives you everything about how NEAT affects your fat loss and muscle gain efforts, plus what to do about it.

Cognition and Nutrition
Ever wonder why I’m such a big fan of carbs and creatine? In this lecture, I’ll show you how to turn up the brain juice and maximise your cognition with your food.

Dieting without Tracking
One of my most popular lectures. We go into how to set up a nutrition strategy without explicit tracking, how to set up a hybrid model that transitions between strict tracking and intuitive eating, and scientifically-validated psychological techniques to help your clients deal with the complexities of eating intuitively.

Exercise Selection in Detail
How do we determine what makes a “good” exercise for a specific body part? How can we individualise exercise selection? How does exercise execution play a role in training effectiveness?

Chrononutrition in Detail
Meal timing is fundamentally not as important as energy balance, but emerging research is showing just how powerful it can be when used correctly. Individual prescription of macronutrient timing and energy balance throughout the day can make good results great by affecting muscle protein synthesis, blood glucose control, appetite, and sleep.

The best programming means nothing if your clients can’t stick to the plan. The science is only one half of results – the other half is the art of coaching. You’ll learn how to deal with individual circumstances around your clients to get the best results.

Constrained Total Energy Expenditure
Is there a limit to how much we can tinker with energy in and out before the brain takes over? Recent research indicates there’s far more going on under the hood than simply moving macros up and down.

Glycine and Collagen
Sometimes it’s fun to extrapolate from research and mechanisms. There’s potential for glycine consumption to help with aging, skin quality, connective tissue, and oxidative stress – but only if it’s done right.

Sleep, Fat Loss and Athletic Performance
Sleep is huge. More and more, people are realising that there’s nothing a good night’s sleep can’t help with. We dive into the research and let me tell you – the numbers will blow your mind.

Gut Microbiome
Probably the most oversimplified topic in health. This lecture serves as a primer and overview of the different types of bacteria in our guts, whether supplementing with probiotics is helpful (and under which circumstances) and what to do about antibiotics

...Plus Even More

  • Training Fatigue and how it affects your programming
  • Pain, injuries, and how to get back on track faster
  • Oxidative stress - what the hell is it, and what should you do about it?
  • Food processing - fresh or frozen? Grilled or boiled? Juice or whole fruit? Max your micronutrition with the answers to these questions.
  • The Power of Placebo - how belief affects your results

Deep Dive Group Calls… Live

Everything above is waiting for you the moment you join Science of Fitness. And you’ll find plenty of quick wins you can apply immediately to your own work or with your clients.

However, there are some more complex topics to tackle, and you might have questions. To help you with those, I’ll be holding weekly live group calls. You’ll get the same detail and cutting-edge research as in the rest of this course, but these live sessions give you the chance to ask questions and challenge me on anything we discuss.

Don’t worry if you can’t make a session or two, as each one will be recorded for you to watch (or rewatch) whenever you like.


40+ hours of videos & lectures that shows you the science behind health, fitness, and high performance

Initial 1-on-1 call with Luke to set up your personal study plan so you know exactly how to hit the ground running

Lifetime access to the program so you can review and refresh your skills whenever you need

Weekly group calls so you can ask questions and discuss topics directly

Mobile app, so you can study even when you’re not at your PC

Instant access that lets you find quick wins for clients (sometimes within an hour or two)

60 Days Risk-Free To Transform Your Coaching

I stand behind everything I’ve said here, but there’s no way around it: The Science of Fitness will cost not just financially, but in terms of time and effort you have to put in. And I understand that you might hesitate.

To give you a safe way to test whether the Science of Fitness is for you, I’m offering a 60-day, 100% money-back guarantee. Join the program for two months, and if you’re learning things that change the way you’re coaching, keep going. If you decide this isn’t what you need, you can opt out any time within those 60 days and get a full refund.

In fact, if I can make a suggestion: sign up, book in your study plan call with me and work through the first two modules, as well as attend the first live group call. If after doing those, you feel what you’ve learnt won’t help you get better results for clients or make you a better coach all-round, you’ll get your money back, no questions asked.




Become A Greater Fitness Expert
For Less Than A Weekly PT Session

As an established coach, clients aren’t paying you for your time.

They’re paying you for:

  1. Your expertise
  2. What you can do for their fitness

The deeper your knowledge, the more you’re able to do for clients. And when you can achieve results for them that few others can, the more you’re in demand and the higher your rates climb.

The Science of Fitness is where you get that deeper knowledge... for less than what your run-of-the-mill Sydney PT charges for a single 45-minute session.

You won’t be getting run-of-the-mill study, though. This is some of the most meticulously researched material on fitness you’ll find anywhere.

In the first few weeks, you’ll uncover quick wins that will let you see results right away.

In the long run, you’ll have a sophisticated understanding of health and fitness that few other coaches in the world possess.


Important: If you’re reading this, then you’re one of the small number with the opportunity to join. I know not everybody who follows me wants to level up their coaching game to this kind of degree. With that in mind, The Science of Fitness will only be available until Tuesday 26 January 2021, which allows me to get started helping the coaches who join. 

There will be another intake down the road, but I’m not sure when it will be (these take a lot of work, so I can’t commit to anything).

Click below on whichever option suits you best, and let’s start to give you greater results, greater satisfaction, and the path to make you a greater coach.

I’ll see you inside.

Please Read Before You Buy

Yes, I’ve already spoken about the pandemic, but I want to ram this home.

The Science of Fitness was designed and first run in a different world to the one we’re now in.

Today, it would be easy to go with the “more than ever, you need skills to stand out” argument. And it’s true. Even in a fitness industry shattered by the last few months, those with the sharpest skills will generally rise to or stay at the top.


While I believe this program is one of the best ways to learn the principles that will change your clients and your career, these are unprecedented times (as every second ad on TV loved to tell us).

So, if you’re not in a position where you can join, I ask you to do one thing: DON’T.

I want to help people become better coaches, not bankrupt them.

This won’t be the last time I run the program, even if I don’t have a set date beyond this round. In that time, you can still learn a mountain from my Instagram posts. If you can’t get your fill of me that way, my podcasts cover all kinds of related topics. On a more serious note, there are plenty of great books you could work through to get a very basic understanding of the principles this course gives you.

Whatever you choose, you’ll be improving yourself as a coach and a person. And that’s the most important thing any of us can do.
