When I was in college and first getting into the strength and conditioning field, I was obsessed with trying to get stronger. I read almost anything I could find that promised to help me do that in the shortest time possible.
Somewhere in that process, I stumbled upon a strength program claiming to be based on how the Bulgarian Olympic Weightlifters in the 1980’s trained and won so many medals. Though I can’t remember the exact name of the program, the authors claimed the real secret to building strength was doing 2-3 short, high-intensity training sessions per day, six days a week.
At the time, it seemed reasonable enough to me. Maybe training non-stop and using massive volume really was the secret recipe for getting insanely strong?
I had never tried it before, so I figured it was worth a shot and I got to work. For the next 12 weeks, pretty much all I did was train… all the time.
The results? I actually got pretty damn strong!
All my major lifts went increased 30-40 lbs or more and I gained 5 lbs. No doubt, I was definitely bigger and stronger. In short, it worked.
Maybe the Bulgarians really did know what they were doing?
A different time, a different result
Fast forward about 6 years. I was now in my mid-20’s and was running my own gym. Truth be told, I was so busy training people every day and trying to build my business that I’d let my own fitness slip.
I’d been doing a fair amount of conditioning, but I felt weak. I had definitely lost muscle since my college glory days. I decided I needed to do something about it. So I dug through box after box in my mom’s garage until I found the old Bulgarian strength program.
I made a few changes that I thought would make the program even more effective and then got to work. Once again, I was lifting heavy 2-3 times a day, 6 days a week.
The results this time? Let’s just say they weren’t quite the same as before.
This time around, the program absolutely crushed me.
I got stronger the first few weeks… but it was all downhill from there. It wasn’t long before my joints started hurting and I felt sore and tired all the time. I did all the workouts and I trained as hard as I could, but it wasn’t anything close to what I would call “fun.”
By the time I got halfway through the program, I was sick of lifting weights altogether.
Why “training hard” can lead to failure
It took me many years to fully understand what went wrong the second time around, but I’ve since come to realize that it all starts with what I call “the intensity mindset.”
What is the intensity mindset?
Simply stated, it’s approaching fitness from the idea that the single most important variable driving your success and results is how hard you train.
This mindset quickly extends to thinking that if you’re not seeing the results you want, it must be because you’re not training hard enough.
Or, just as commonly, if you’re training hard and seeing some results, then training harder will lead to even better or faster results.
The mindset that intensity is what drives results and there’s no gain without pain has been around in fitness for a long time. But the rise of CrossFit, Tabata intervals, and boot camp classes in the last ten years has only ingrained it deeper and deeper into the fitness culture.
Unfortunately, there’s one big problem with the intensity mindset: it doesn’t work.
In fact, it often ends up causing more harm than good in the long run. I’ve come to realize (and I have proof) that it’s the single biggest reason so many people put in the work and yet ultimately fail to reach their health and fitness goals.
Let me explain…
It all comes down to energy
To really dive into why the intensity mindset fails, we have to start by talking about energy. Every single one of our trillions of cells needs a constant and unending supply of energy to function and keep us alive.
Everything from our brains, to our muscles, and even our bones all rely on ATP, the energy currency of the body.
While the need for energy is obvious and something most people understand, what’s much less clear is how training, stress and recovery are all directly related to energy and the results they see in the gym.
It’s because of this relationship that the intensity mindset is always destined to fail…
Why your Fitbit is a liar
One of the most important components of energy that’s come to light in recent years is that our body has a much more limited capacity to produce it than we realized. You see, most people believe that if they take more steps and are generally more active, it means they are burning more calories – i.e. their body is producing more total energy.
This idea has been repeated over and over again from pretty much every area of the fitness industry, from trainers and coaches, to nutritionists and everyone in between.
Move more, burn more. This is what’s known as the Additive Model of Energy Expenditure — which is just a fancy way of saying that the higher your level of activity, the more calories your body will ultimately burn.
This well-known concept is modeled in the graph below. You can see that “other” represents the amount of calories you burn at rest (your RMR) and PA stands for physical activity. In this model, the more physically active you are, the more total energy (calories) you burn in a day.
Although it makes perfect sense to think that this is the way the body works, more and more evidence is showing us that it doesn’t work this way at all. Instead, new research is painting an entirely different picture of metabolism and how our body adapts to different levels of physical activity.
In a research paper titled, “Constrained Total Energy Expenditure and Metabolic Adaptation to Physical Activity in Adult Humans,” researchers studied the physical activity levels and energy expenditures of five different groups of people living across the US and Africa.
Now, common sense among most of the diet gurus out there might tell you that the populations in Africa that lived a more traditional hunter-gatherer lifestyle must have burned way more calories than us Americans because they were more active.
The research, however, found otherwise…
“People in less socioeconomically developed populations, including subsistence farmers and traditional hunter-gatherers, have total energy expenditures similar to those in more developed populations.”
The important thing to understand here is that the researchers didn’t just use a Fitbit, or some other accelerometer, to determine energy expenditure (calories burned) like most people would have to. Instead, they used a much more sophisticated technique called doubly labeled water.
This method provides a much more accurate gauge of how many calories your body is really burning because it’s measuring your metabolism, not just how many steps you take. When all the data was taken into account, a totally different view of the relationship between how active you are and how many calories you burn emerged—a model called the Constrained Model of Energy Expenditure, shown in the graph below.
In short, what this model shows us is that our metabolism doesn’t work the way we’ve always thought that it did. It turns out that if we walk 20,000 steps in a day, we don’t actually burn any more total calories than if we walked 10,000 steps.
Instead, when we walk 20,000 steps, our body simply redirects energy from other biological functions to meet the demand – we’ll talk more about the specifics of that shortly.
Although it may seem crazy to suggest that people living in hunter-gatherer tribal societies don’t really burn more calories in a day than most Americans – when corrected for body mass – it’s what the research shows.
This new model of energy expenditure makes it clear that there’s an upper limit to how many calories we can burn in given a day. No matter how active we are, it turns out that our metabolism is ultimately limited in the amount of energy it can produce and thus the amount of calories we end up burning.
A great view of how this all works can be seen from looking at a similar study, titled “Increases in Physical Activity Result in Diminishing Increments in Daily Energy Expenditure in Mice,” where researchers looked at different activity levels and energy expenditure in mice using the same doubly labeled water technique.
As you can see, the mice that were moderately active did, in fact, end up burning more calories than the mice that were couch potatoes. The highly active mice, on the other hand, essentially burned the same amount of total calories as the moderately active mice.
Again, this supports a model where our metabolism has its limits and the maximum amount of energy our metabolism can generate is much more fixed than we ever knew.
The importance of this new way of looking at energy and its relationship to activity cannot be overstated – it explains a lot.
The energy dilemma and why it’s so crucial to your fitness goals
Now that we know there’s only so much energy our body can generate in a day, let’s look at different processes in the body that are constantly demanding it. We can group these demands into three broad categories:
- vital biological functions
- physical activity and stress, and
- tissue repair and adaptation.
It’s important to consider that ultimately, it’s your brain and its complex computing power that decides where the energy you produce gets distributed.
Your Brain’s First Priority: keeping you alive
Out of the three categories of energy demands, your vital biological functions (the energy that vital organs like your heart, lungs and brain require) are obviously the most crucial to survival.
When any of these tissues don’t get the energy they need, well, let’s just say it’s quickly game over.
Because of this, your brain’s first priority is always going to be directing energy to these areas, since there’s an absolute minimum amount that your body needs to stay alive in a day. This number is often referred to as your resting metabolic rate, or RMR.
Your Brain’s Second Priority: powering your activity and dealing with life stress
The second category, physical activity and stress, is the most highly variable from day to day, and it’s also the one we have the most control over. We can choose whether to work out or sit on the couch. We can take the stairs or the elevator.
While it’s fairly obvious that the more physically active we are, the more energy our working muscles and supporting tissues will need, what most people don’t fully appreciate is just how much mental stress also affects our energy distribution.
The critical thing to know is that any time we’re mentally stressed, whether it’s because of an upcoming work deadline or test, financial worries, family issues, or because the driver in front of you is going slower than you’d like them to, our body’s stress response is activated.
When this happens, stress hormones are released into our bloodstream, our blood pressure increases and our brain works to mobilize our energy stores. While this is exactly what you need when dealing with a physically demanding stressor, like working out (or being chased by a bear), it’s not so great when the thing stressing you out is a slow driver.
This is because after the driver moves out of the way, or your exam is over, or the bills get paid, and you’re able to relax, then your body then has to put back all the energy it just mobilized but didn’t end up needing. Moving all this energy around, from storage to the bloodstream and back again, takes a good amount of energy in and of itself.
Another way to think of it: Imagine a warehouse where the workers are constantly having to get big, heavy boxes down off the upper shelves, only to put them back up there again minutes, or hours later. It’s not the most valuable way for them to spend their precious (limited) time.
In other words, there’s a real biological cost to mental stress and it’s paid in the form of energy. In my experience, the stress of life is a lot more expensive and plays a much bigger role in fitness, or lack thereof, than most people ever realize.
Your Brain’s Last Priority: improving your fitness (making you bigger, stronger, leaner, and meaner)
The third and final category of metabolic activity that demands energy is tissue repair and adaptation. When you’re training hard and trying to improve your fitness, it’s absolutely vital that enough energy gets distributed here. This is the energy that’s used to rebuild muscle tissue to make it bigger and stronger, to create new mitochondria that improve endurance and even to make changes in the brain that lead to enhanced coordination and skill.
If your goal is to get the most out of your training, the crucial thing to realize is that the brain is only going to devote energy to building bigger and stronger tissue when there is enough left over after your other basic metabolic needs and physical activity demands are met.
Your brain is definitely not going to sacrifice any of the energy it needs to keep you alive just so you can lift heavier weights, run faster, or look better in a bathing suit.
“Recovery Debt”: where fitness goes very wrong
When you consider the limited nature of our metabolism and all the energy demands within the body, it should be easy to see how so many training programs built around the intensity mindset end up going wrong.
Looking at the different stages of the training process in the diagram below, the biggest thing that stands out is that training, recovery and the adaptations within the body that drive improvements in fitness all require a massive amount of energy.
The harder you train, the longer you train for, the more energy your brain has to distribute to your working muscles and other tissues. At the same time, repairing all these cells and rebuilding muscle, mitochondria, tendons, and trillions of cells to make them bigger, stronger and capable of greater endurance also takes a massive amount of energy.
Given that our metabolism can only produce a finite amount of energy in a day, no matter how much food you eat or rest you get, what do you think happens when you pile on three, four, or even five high intensity training sessions a week? What about when you couple all that training with the stress of daily life?
The answer is simple: you end up with what I call a recovery debt.
A recovery debt is what happens when you put a ton of stress on all the cells and tissues involved in training, without also giving them the energy they need for recovery and repair. You go in the gym, day in and day out, busting your ass and lifting weights, doing endless intervals, pushing yourself to the edge of fatigue and yet it never quite seems to pay off the way that it should, or the way that you thought it would.
What I’ve come to discover in the last few years is that the single biggest thing holding people back from reaching their fitness goals is exactly that: they are living in a constant state of recovery debt. I even have over 1.5 million heart variability data points from more than 15 thousand people that proves exactly this. (I’ll discuss that in more detail in the next article in this series.)
What the data shows is that most people are putting in the work but not getting the reward for one reason and one reason only: they are spending so much energy on training and dealing with the stress of daily life, that there’s just not enough left over to go towards recovery and rebuilding the body.

The negative consequences of “pushing through it” — and how your body fights back
The truth is that this is what the intensity mindset inevitably leads to and why fitness fails so many people. If you start with the belief that the most important thing to driving results is intensity, then you keep adding more and more of it until your body can’t keep up.
You start to feel tired and sore all the time, but you push through it. You have nagging injuries starting to creep up, but you keep going anyway. Your strength and/or endurance aren’t really getting better, but you convince yourself it’s only because you’re still not doing enough. Work is stressing you out and you’re not sleeping well, but you think the best way to relieve stress is to sweat it out in the gym.
Sooner or later, if you build up a big enough recovery debt, the body starts to fight back. Changes in dopamine function within the brain drive you to want to eat more and move less. You lose motivation to go to the gym, or you get to the gym but you just can’t push yourself as hard. Eventually, you find yourself mostly just going through the motions.
This is the daily grind that literally millions of people are putting themselves through. They are putting in the work but not seeing the results, and the harder they work, the worse they eventually start to feel.
This is also exactly why I didn’t see the same results from the Bulgarian training program the second time around. I wasn’t in college anymore. I was working 60+ hours per week and dealing with the stress of running a business. The stress of life was taking a ton of energy away from recovery and my body simply couldn’t keep up.
Fortunately, over the last few years I’ve put together a whole new way to approach training and fitness in general. One that is more effective, built on the real science of how the body works, and one that starts with an entirely different mindset…
Recovery-Driven Fitness: a new model of training, eating, and living your life
The idea of building an approach to fitness around recovery instead of intensity isn’t one that I just stumbled upon by accident. It’s not a fad, gimmick, or just another empty promise or sales pitch. It’s also not just more same old advice to get more sleep or spend more time relaxing. As you’ll soon discover, recovery is so much more than that.
Instead, it’s an idea that stems from my nearly 20 years of experience in the fitness industry spent training people of all levels and abilities, talking to coaches, fitness professionals and researchers from around the globe. It also comes from using machine learning algorithms to crunch the numbers from my database (the largest in the world) of more than 1.5 million heart rate variability measurements collected over the last 6 years.
What my experience and the data both clearly show is that a new approach is needed, one that considers that results are driven more by the energy that’s put into recovery than just the intensity that’s put into training.
What is recovery-driven fitness?
In the simplest of terms, recovery-driven fitness is a new approach to how you train, how you eat and how you balance the stress of life that’s built around maximizing recovery rather than just intensity.
Recovery-driven fitness starts with the mindset that the most effective way to reach your fitness goals isn’t just by training harder, but by incorporating specific strategies and methods that help shift your body put into a recovery state.
It’s only in the recovery state that the body is able to focus its energy on recovering and rebuilding itself to be stronger and better than ever.
Over the next 3 articles in this series, I’m going to share with you an entirely new way to approach your fitness. I’m going to lay out a recovery-driven fitness blueprint and show how to build a training, nutrition and lifestyle plan that drives recovery in a whole new way and delivers far better results than a plan built around intensity ever could.
Here are just a few of the things I’m going to cover:
- A step-by-step guide to how you can use recovery-driven training sessions (HPRT) to push your body into the recovery zone and accelerate results.
- How to leverage technology to measure and track recovery, without letting yourself get lost in all the data.
- Why the common approach to dieting and nutrition can often slow down our recovery rather than speed it up.
- The most effective lifestyle strategies that you can put to work right away to help your body get the most out of your workouts.
- Targeted supplements that you can use to help redirect your body’s energy into recovery and prevent recovery debt.

The World’s First Digital Recovery Coach is Available to Order December 18th
The pervasiveness of the high-intensity mindset is one of the biggest reasons I’ve spent the last two years creating Morpheus, the world’s first digital recovery coach. I wanted to build something that could help people connect the dots between the different areas of their lives in more meaningful and powerful way, while giving them concrete guidance how to balance training with recovery.
Morpheus does exactly that by analyzing your activity, sleep, training and heart rate variability on a daily basis and showing you how they’re all connected to your recovery. Even more, he uses machine learning algorithms to find your own recovery zone each day so you can be much more precise in your training and shift your body into the recovery state.
Morpheus is the first technology designed to help make living a recovery-driven life as easy as possible, and he’s coming to life on December 18th. To learn more about how Morpheus works and what he can do for you, take a second to watch the video below.
