"Why Lactic Acid Will Help You Gain Weight Naturally"

In my last article, “To Gain Muscle Weight, Go For The Burn”, I began to detail why most bodybuilding workout programs are dead wrong in concentrating on the “numbers” game instead of going off of the “feedback” your muscles are sending you as  you are training them.

If you didn’t get a chance to read it yet, please do so to better understand what I’m going to continue to discuss in this article.

But one of the things I had written was that it is absolutely crucial, if you’re looking to build muscle mass and gain weight, to make sure that you’re causing certain feedbacks within the muscle to occur while training. 

There are several internal feedbacks that will let you know without a doubt if you are training properly. 

The first one I’ve been discussing has been lactic acid formation (the so-called “burning sensation”).

If you aren’t feeling this within the muscle, you aren’t going to build as much weight or muscle as your genetics will allow.

I want to go further into detail as to why lactic acid formation will help you gain weight naturally… 

As explained in the last article, lactic acid forms in the muscle when fresh oxygen is not allowed to enter the muscle during a set. 

This occurs when you use a high number of reps during every set, as the pressure / pump begins to build up within that body part. 

Now, that’s not all that happens with the formation of lactic acid.

The more lactic acid that forms (…in other words, the greater the burning sensation and pain…), the greater the amount of growth hormone (HGH) and IGF-1 forms as a response to that.

As you may already know, growth hormone and IGF-1 are two of the main hormones that are responsible for building muscle mass.

As a matter of fact, these are two of the main substances that many bodybuilders and athletes inject to gain weight in the form of muscle tissue.

In addition, when lactic acid forms in a muscle being trained, two processes called muscle satellite cell proliferation and muscle satellite cell activation come into play as a result. 

These two processes are also important pieces of the muscle gaining process. 

But wait, there’s more! 

As a result of lactic acid formation and low levels of blood oxygen within the muscle being trained, all muscle fibers are called into play to help out….slow-twitch, fast-twitch, etc. 

So, again, ensuring that you are triggering specific feedbacks from the trained muscle, such as the burning feeling, aka lactic acid formation, is crucial in making sure that you are stimulating muscle weight gain from your workout program.

As this article has pointed out, the hormonal, metabolic, and fibric responses to the increase of muscular lactic acid and the lack of fresh oxygen in the area all play a huge role in building a muscular physique.
