Cortisol is one of the most important hormones in our body. It’s been called the “stress” hormone because it’s released during moments of stress.

But it’s also the hormone that wakes us up in the morning, that starts the healing process in our body after any injury or workout, and that provides us with energy and mental focus when we’re “running low.”

But unfortunately, when cortisol levels go too high, it becomes something else.

It can cause muscle loss and prevent muscle gain, cause fat storage and prevent fat loss even when we’re exercising, cause low energy levels, cause us to feel stressed, cause poor sleep, and even slow or prevent healing and recovery.

If you have trouble with any of the above, it’s likely that higher than normal cortisol levels play a part.

But that’s when it’s too high. And, unfortunately, for many people in society today, it already is too high.

So let’s dive in and see what cortisol is, how it works and how we can balance our levels.

We’ve all seen energy drinks advertised on social media, by influencers, and even by athletes.

And the number of people drinking these on an almost daily basis has been growing for years.

But the effect these energy drinks, as well as high levels of coffee have on our bodies, our health, our sleep, our stress levels, our mood, our hormones, and our ability to lose body fat and gain lean muscle is much more than most people think.

These energy drinks have high amounts of caffeine, sugars, and processed sugars, often under the guise of several different ingredients so you don’t see quite how much is in there.

While they may list 160 mg of caffeine as an ingredient, other ingredients listed supply even more caffeine and other types of stimulants.

How much stimulant is actually in them? I don’t know. But much more than anyone needs, especially when they’ve usually already had a couple cups of coffee in the morning.

And, while having one once, or very infrequently, may not be too bad, when continued over time, these can have a very significant impact on our long-term health, our aging, and our body’s ability to function at optimal levels.

Beyond this, many people who drink these are in their teens or twenties, when their bodies are still developing and growing, and the damage they do here can be far worse, leading to acute or even chronic health issues in the future.

This may seem small, but due to their prevalence and availability now, it’s very important.

In this article we cover how this works, and even go into the sleep/wake cycle, what occurs there, and how this affects it.

Getting good sleep is one of the most important things we can do, not just for muscle building and fat loss but for our mood, energy levels, and overall health.

Sleep is when our body is able to recover and repair cells, a lack of it even affects our aging process, speeding it up internally, as well as visibly causing wrinkles and sagging skin.

During the first few hours of deep sleep is when many hormones, including growth hormone and IGF (major fat-burning hormone) are released.

Getting enough sleep also helps to keep cortisol levels lower and balance estrogen, testosterone, progesterone and thyroid.

So if we want a lean, toned or muscled body, then we need deep sleep every night for full recovery, muscle building, natural fat loss and hormonal balance.

Yet a third of Americans get poor sleep, and those with the worst sleep generally have poor health.

So what causes this and what can we do to not only get better, deeper, more refreshing sleep, but also to reverse the effects of poor sleep?

Let’s dive in and see.

If we want a fit, lean, healthy body that lasts into our later years, then we need to not only put in the work and eat right, but we need to be able to spot any pitfalls in our path and handle them before they become a problem.

I'm talking about illness, physical issues, organ troubles, cardiovascular issues, etc.

Many things can exist and are quite visible or easy to spot. But only because they've become big enough to spot. However, there was a point before they became big enough to be visible when they were harder to spot... but much easier to address.

Health troubles can exist without us knowing, leading to troubles we can see later on, if only because they've gotten worse.

They can even impact our ability to build muscle, recover, or lose body fat, without us ever knowing they were there, existing.

But if these things are still too small to see right now, then how do we know? And how can we catch them before they become a problem?

That’s where Heart Rate Variability comes in.

Heart Rate Variability, or HRV, is a literal measuring stick of our current health and how well our body is able to adapt and recover. And it’s something we can use to monitor ourselves.

Whether we're into extreme sports and maximum physical performance, or trying to achieve optimal health for a long life, learning what HRV is, and how to use it, puts our health and performance in our hands.

This helps us spot trouble when it’s still a ways away, so we can handle it before it gets out of hand.

There is something that will directly improve our ability to recover, our performance, our overall energy levels and metabolism, and which is key to overall health more than almost anything else (though we'd never think it was).

This is something that very specifically controls or improves or decreases our body's overall ability to repair itself, recover, and function correctly.

It directly affects our longevity, our ability to gain lean muscle, our cardiovascular health, our ability to keep weight off more easily, our energy levels and mood, and which allows us to keep improving over time.

And it's also something that directly affects and increases or decreases our overall health.

It's called VO2 Max. V is for Volume, O2 is for Oxygen, and Max is for Maximum.

VO2 Max is literally the maximum amount of oxygen our cells can use to produce energy at any given time. It's how much horsepower our body has.

A person who is unwell in one way or another has a low ability to produce energy. A well person has good energy ability. And an athlete has high energy production capability.

Conversely, a person who has a low ability to produce energy will become unwell over time, and a person with high energy production will remain well, barring emergency situations.

From a performance view, VO2 max is literally the maximum amount (volume) of oxygen that your cells can utilize to produce energy during intense exercise before you burn out.

Our cells only have so many energy-making "engines" (mitochondria). So even if we increase oxygen to the cells, if there are not enough mitochondria to use that oxygen, we don't increase energy.

If we can increase the number of these engines, our body's horsepower, then we increase our VO2 Max, and how much energy we can produce.

Raising this allows us to raise overall performance, energy, endurance, recovery ability, and overall health. And leads to greater longevity.

Let's dive in.

When working out, blood flow is very important for both muscle building and fat loss.

It’s how the nutrients, water and oxygen needed for energy creation and muscle creation flow to our cells.

If our blood flow is lower, our cells do not get these nutrients or oxygen fast enough and our energy levels go down during high intensity workouts.

And it slows recovery.

Achieving healthy blood flow then is important for maximum results and maximum overall health.

We've spoken a lot about hormones on the Lean Body/Lean Bulk Program, but not how toxins affect these.

Testosterone levels have been dropping for decades and the largest lab testing company, Lab Corp, actually lowered the standard of what “acceptable” testosterone levels are.

At the same time, estrogen levels have risen sharply in both women and men, and thyroid has become a growing issue. 

All of this affects our ability to build lean muscle, lose body fat, and maintain heathy levels of lean muscle and fat. And it lowers our overall mood and health.

But while we've covered individual factors that can cause specific hormones to go too high or too low, there is another factor that affects them more broadly, and significantly.

There are exact chemicals in the environment (in our food, air, and water) which didn't exist before.

And these chemicals can do several things in the body:

They can block certain hormones from being created.

They can block them from being able to communicate their instructions to a cell, or disrupt the cell's normal actions.

Or they can impersonate certain hormones entirely, giving our cells the message a hormone normally would, but not when the brain says to.

And while this affects muscle-building and fat loss significantly, its effect goes far beyond this. 

It isn't a small issue. And every year its effects grow.

In this article we cover what's happening and what you can do about it.

If we want to build and keep lean muscle, or have a lean, toned, and shaped body without the excess body fat, there are key hormones we need to look at:

Cortisol is our stress hormone, released in times of physical or mental stress. It's necessary, but when it goes too high it acts to break down the muscle we do have, prevent or slow new muscle gain, and create and hold onto body fat.

Estrogen and Insulin also play a large role here. 

On the other side we have Growth Hormone, Testosterone, and IGF, Hormones that act to repair muscle, bone, ligaments, etc, build lean muscle, burn excess body fat, and shape our body in both men and women.

But cortisol, estrogen, and insulin work on a sort of seesaw-reaction basis with growth hormone, testosterone, and IGF. 

Raise one side and the other side lowers, and vice versa.

Increase cortisol and we decrease testosterone and growth hormone levels, causing fat gain, preventing muscle gain, and even breaking down the muscle we do have. 

But raise testosterone and growth hormone and we lower cortisol, estrogen and insulin levels.

So while we've covered how to prevent cortisol, estrogen, and insulin from going too high in the above linked articles, in this article we cover how to increase levels of growth hormone, testosterone and IGF.

Let's dive in.

As we go through this challenge, our hormones are balancing to allow for maximum muscle building and swifter fat loss.

So I want to cover the points that can either prevent muscle gain, or slow it, and the things that allow us to maximize muscle gain and fat loss, and speed recovery from workouts.

And the first thing we’re going to cover is what slows muscle gain, or out-right prevents it, by slowing the protein synthesis necessary for the recovery, repair and building of lean muscle.

This is the first issue in a series on Extreme Athletes, those who push themselves to the max to achieve their goals and, possibly, greatness.

But, while the information in this series applies very strictly to extreme athletes, it applies just as much to anyone else trying to achieve peak performance for themselves in fitness and athletics, while staying healthy overall.

Also, while we will cover points individual to specific sports, most of the information is applicable to all sports and performance, energy, and recovery as a whole.

In this first article we’ll start with one of the key, over-riding aspects to maximize not only the ability and performance of an elite athlete, but of anyone.

Because, when you put your body through as much stress and pressure as an athlete does, every one of your organs, muscles, nerves, bones, hormones, etc., all play a part.

And, while any weak links will bring down the rest, improving any weak spots in health will help increase the energy production and performance of the overall.

Anyone who works out, runs, bikes or does any type of intense exercise, knows about DOMS — Delayed Onset Muscle Soreness.

This is the soreness you feel not right after a workout or exercise, but 24-48 hours later.

At one point it was thought this was caused by lactic acid build up, but this isn’t the case.

(Lactic acid is an acid that starts to build up just before we reach our VO2 Max and can’t go any further in our exercise or workout.) But lactic acid actually helps you. Your body can metabolize it (burn it and use it as fuel).

So what really causes DOMS? And how can we prevent it or lessen it?

Let’s see.

We know about amino acids, hormones, and how different foods affect our ability to build lean muscle, burn fat and stay healthy.

But if we want to achieve maximum levels of energy, recovery, health and performance, and build the most lean muscle, then we need to go down to the cellular level.

After all, our bodies are just one big mass of some 100 trillion cells all bonded together.

How well we're doing is an exact reflection of how well our cells are doing.

And they require a multitude of nutrients and biochemicals, all held in equilibrium, to ensure they can work properly, produce energy, build muscle, and keep our body going.

When these aren't properly balanced we can get headaches, brain fog, low levels of energy, muscle cramps, slower recoveries from workouts, and imbalances in hormones.

But when everything is in place, we have the most powerful you that you can be.

So let’s see how this works.
