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.

Ask anyone about bulking and cutting and they’ll bring up calories and macronutrients.

“You have to count your calories and macronutrients and make sure that you eat more than you need to build muscle (and body fat) and eat less than you need to burn fat.”

And that’s true… to a degree.

But there’s more to it. And if you just follow the above, you’ll more than likely miss your goals.

Yes, we need to measure the amount of calories to make sure we get enough energy, but not too much. And we need to make sure we get enough protein, fat and carbohydrates so we can build muscle or have energy to power us through the day.

But… which proteins, fats, and carbs? And how do they affect the hormones that will determine how they’re used?

Because it's our hormones that decide how these macronutrients will be used in our body.

Will the carbs and fats be turned into body fat? Or used as energy? Or will they become part of the structure of the body?

It’s our hormones that decide.

Will this protein be used to build muscle? Or will it be turned into sugar or body fat?

Hormones decide.

It’s not how much you eat that decides. It’s which exact food you eat and how that exact food affects your hormones.

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.

When we look at Lean Bulking, building lean muscle without the excess body fat, we need to look back at what the original body builders did, the golden age body builders.

Because it was very different to what is done now.

And I'm not talking about the 70s or 80s when counting macros and Bulking & Cutting became popular.

We're going earlier.

To the time of Jack LaLanne and the other greats, before egg protein powders, whey powders, creatine, and BCAAs were first introduced.

Back then body builders ate very differently. But very effectively.

Welcome to the fully updated Lean Body/Lean Bulk Guide & 30-Day Challenge!

This guide and the accompanying protocol aim to achieve one of a few things, depending on what your goals are.

You may just want to attain a lean, toned and shaped body. An hourglass shape for women or a V-shape for men. This is the Lean Body portion of the protocol.

You may want to build significant lean muscle without adding excess body fat that has to be worked off afterwards through cutting or fasting.

Or you may what to achieve something somewhere in between.

That’s fine. This protocol was designed to be tailored to you — where you are at now and where you want to be — so you can achieve your goals.

But this isn’t just a program where you count calories and workout.

No.

If we want to build lean muscle without the excess body fat of bulking, or attain a lean, toned and shaped body and keep it, we need to do more that.

We need to look at digestion, cravings, recovery, sleep, energy levels, blood flow and hormones.

Bulking and Cutting has been around for decades now.

We work out hard, we count our macros, and eat and eat and eat.

And we build lots of muscle.

But at the same time that we’re building muscle, we also build body fat. And we build each at about the same rate, a pound of muscle for a pound of fat.

Then we do a cut, cutting back on our calories, and in some cases starving ourselves (which is never necessary), and do a lot of extra cardio — running, biking, sprints, etc. — all to lose that extra body fat we gained.

And hopefully we don’t lose too much of our muscle gains in the process.

Now, I have no problem if someone enjoys that. Many people do. But many others don’t.

And the thing is, it isn’t necessary.

At all.

If you’d like to build lean muscle without the excess body fat, either to build significant muscle or just to tone your body, and all while raising your overall health, energy levels and mood, then the Lean Body/Lean Bulk Protocol is for you.
