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.

Did you know too high cortisol levels not only build excess body fat, but prevent protein synthesis and actually break down our muscle?

The hormone cortisol is vital to our body, but when levels get too high it can cause us a lot of trouble.

It can raise our stress levels, making us irritated, and cause us to have poor sleep.

It can reduce blood flow, cause lactic acid to build up in our muscles, cause muscle breakdown, and slow muscle recovery.

It lowers our testosterone, growth hormone, and progesterone levels, hormones necessary to build muscle and keep off excess body fat, while raising estrogen levels.

It can damage our cells and increase insulin resistance which then leads to high levels of insulin in the future and higher levels of body fat, especially around our mid-section.

It makes deep sleep, needed for muscle building and fat loss, much harder.

And it causes our hunger hormone, ghrelin, to be released to make us hungry, even when we're not.

In short, we need our cortisol levels properly balanced for muscle building, fat loss, overall health, deep sleep, and the best results possible.

In this article we cover how cortisol works and what we need to do for balanced cortisol levels that allow us to have the body we want.

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.

But it's also something which, when we address it, not only lessens DOMS, but improves overall recovery and sleep for faster lean muscle gains and fat loss.

At one point it was thought this was caused by just 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. (VO2 Max is the Maximum amount, or Volume, of Oxygen (O2) that your cells can utilize during intense exercise, before you burn out.)

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.

Those are some big claims in that title.

And how could they be true when we have statements like:

“BCAAs stimulate the building of protein in muscle and possibly reduce muscle breakdown.”

“Valine is needed for your muscle fibers to fire, for tissue repair, and for the maintenance of proper nitrogen balance in the body.”

“Leucine stimulates muscle protein synthesis and may be the dominant fuel involved in anabolic (tissue building) reactions.”

Well, unfortunately, the claims in the title of this article are true.

They come from research studies done on BCAAs, while the above quoted statements come from marketers.

BCAAs, or Branched Chain Amino Acids, taken on their own regularly and over time, can have a significant effect on body fat creation, muscle gain reduction, kidney trouble, type 2 diabetes, metabolic syndrome, and obesity.

And it's becoming quite a problem. Just google "BCAAs side effects" or "BCAAs and Type 2 Diabetes" and you'll find much more than you wanted to.

But how can they say these things and how does this all work?

Let's dig in and see.

Many people think of bodybuilding as just trying to build the biggest muscles we can. And that’s not quite true.

Bodybuilding is about building one’s ideal physique. And, while that includes achieving bigger muscles, it also means achieving balance, symmetry and aesthetics.

But there are those who do try for building the biggest muscles they can, which there is nothing wrong with.

Unfortunately, many of them employ substances which, while helping to achieve their goals faster, and in some cases achieve more than they could naturally, also result in serious health conditions such as Type 2 Diabetes, something which is becoming more and more prevalent amongst bodybuilders today.

In this article we’re going to cover the use of steroids and insulin injections, why they're used, how they work, and how these significantly increase the risk of insulin resistance and type 2 diabetes down the road.

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.

As we enter Week Two, cravings for junk food or processed sugars should be lowering or gone.

And you may not have added much in the way of muscle yet.

That’s fine, you’ve just started and it will come. Right now we’re dialing things in and balancing hormones for muscle building and body fat regulation.

You also may have found it hard to eat all of the natural proteins on the protocol. But this protein is necessary.

Building muscle is about injuring our muscles by putting more pressure on them than they’re used to so they’ll be forced to not only heal, but grow to accommodate the new levels of stress we’ve put on them.

It takes about 90g of pure protein to build a pound of muscle. Most of the rest is fat and water. A pound of muscle is about the size of a tangerine, so even one pound is noticeable if in the right places.

So we need to make sure we’re getting enough protein to not only heal and maintain the muscle we do have, but add to it.

If you’re having trouble getting in all the protein, first, make sure you’re taking your digestive enzymes. Most people’s digestive tracts are not set up to fully digest natural proteins anymore due to our diets. But this prevents us from getting the nutrition we need from this food.

Here we cover the specific supplements and macronutrient you will be consuming during this protocol and exactly how.

This protocol is meant for significantly increased lean muscle, so the macros may seem high to some. 

But it's also meant to be used with the Advanced Workout Regimen, so the macros will be used by our body.

There are three different macronutrient ranges to pick from depending on which Carb to Fat ratio you personally prefer, with notes on each.

There is also an exact way in which you will dial in your macros to ensure you are getting the correct amount for what your body needs.

On this protocol you will be lifting 5 days per week.

As this protocol is very specific to building lean muscle and toning, there will mainly be weight lifting.

There will also be something called Zone 2 Cardio, which will not cause muscle loss, but other than that there is no cardio during this challenge.

If you would like to take a walk, that’s fine. But adding in other forms of cardio could hamper your progress.

And it’s only 30 days.

Okay, let’s run through a few key points and then jump into the workouts.
