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.

In this article we're going to cover something that is key to increasing the overall endurance, performance, and recovery ability of an athlete.

But while it's very important for an athlete, or anyone into fitness of any sort — it’s also important for anyone who is just wishing to raise their overall health and energy levels.

This is because, no matter where we're starting from, very high or very low, if we address it, we can significantly raise not just our energy production and performance abilities, but our overall health, across the spectrum, possibly even removing health troubles we thought were: "just they way it is."

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

VO2 Max literally means the maximum amount, or volume, of oxygen that your cells are currently able to utilize during intense exercise, before you burn out.

Note the word currently.

Because when we raise the maximum amount of oxygen each cell can take in and use, so that they're able to and do use more, we end up raising energy production, performance, endurance, our ability to recover, and possibly even reverse conditions we thought would never go away.

And it's not hard to do.

So let’s dive in.

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.

Most people, when they hit 50, and definitely when they hit 60 or 70, start to lose muscle mass and strength. And most of them think this is just a matter of aging.

But, while aging is definitely a factor here, there is much more going on that is speeding up this process.

I’m 74 years old and I still run in Ironman Triathlons.

I’m strong, I’m lean, and I have more energy than many people half my age. And I’m not alone in this.

So, obviously, age isn’t quite the factor most people think.

But there are key differences between those of us who still keep our muscle and strength, and those of us who don’t. And they’re not genetic.

They’re points that anyone can apply to themselves to start increasing strength and muscle mass again, no matter how old they are.

Most people think of electrolytes as something to take when they’re dehydrated. And this is true.

But there’s much more to it than that.

They allow your nervous system to function, your cells to function, and energy to be created.

When they’re low we can get brain fog, have headaches or back aches or feel exhausted.

They’re even necessary for protein synthesis for recovery and muscle building, and this slows down when we don’t have our electrolytes.

And they’re absolutely vital for hormonal creation and balance.

So let’s take a good look at what electrolytes are and what they actually do in the body. Because they’re very important.

If you’re over 40 years old, you’ve probably noticed that weight loss can become harder.

When we’re younger, in our teens, 20’s and 30’s, we can often (not always) get away with a lot. We can eat more carbs without gaining weight, and keep up our energy and strength levels.

But after 40, things change. And this is a factor in aging. A factor related to changes in our hormones as we age.

What speeds up the aging process and what can we do about it?

There is something called accelerated aging, where aging happens years or decades before it should. And it’s becoming more and more common.

In this article we’re going to dive into exactly what causes accelerated aging, especially aging in our 30’s, 40’s, 50’s… and even our 20’s.

We’re going to cover exactly what is happening to our cells, what is doing this, how this affects aging, and what we can do to prevent it.

Growth Hormone (GH or HGH) is a key hormone that helps us build muscle and burn fat.

Your muscles are made of cells that have been fused together into muscle fibers. And on the outside of these fibers are things called satellite cells.

When you work out you damage cells in the muscle fibers. To fix this, your body releases Growth Hormone, Growth Factors (other hormones) and Testosterone. These tell the satellite cells to start replicating to both repair and replace damaged cells in the muscle, and also to add more cells, increasing the muscle fibers in size.

Someone born in 1950 started out life receiving 50 times less toxins going into their bodies than a child today. Their mother had grown up receiving even less than that and so had less to pass onto them before birth as well.

And they grew up on this much smaller toxic load.

So the amount of toxins injuring or destroying cells was much less.

But now look at where we are today — 50 times as many chemicals as we had then, and many of them are much more toxic.

These very definitely have an affect on our health. In some cases it’s quite obvious, but in most cases it’s something we don’t notice, because it happens over time.

In the last article we covered cortisol, a hormone which, among other things, acts to break down our muscle, breaking down the proteins in it into amino acids, which are then converted to energy sources such as sugar.

At the same time, it holds onto body fat and acts to raise body fat levels, while also preventing protein synthesis for new muscle growth.

But it also lowers key muscle building and fat loss hormones, so let’s cover what those are and how to maximize their production and use within the body for best results.

Did you know that the official measurement of what is considered to be normal testosterone levels has been lowered? 

It has. And this was done because the majority of men no longer fall into the earlier acceptable ranges. 

Their testosterone levels are too low. 

Why is this? What's happening? And why would they choose to lower the acceptable levels instead of addressing why they are lowering?

In this article we talk about what testosterone does in the body, largely from the view of its anti-aging effects, how lowering testosterone levels, not just in the elderly, speeds up our biological aging, and what is causing this.

Did you know that factors such as diet, exercise, toxins, sleep, stress and more can affect how able our DNA are to make new, healthy cells? This is actually a huge factor in aging.

If our DNA can't make new cells properly, but instead make "faulty" cells, then, as our body is nothing but cells, over time our body begins to slowly degrade.

We see it in our skin, our strength, our energy levels and our overall health. This is half of what we call "aging."

But it doesn't have to be this way. This is a created situation. And we can reverse it.
