An Intro to the Overload Principle and Muscle Gain

Building muscle seems to be the endless puzzle people are always trying to solve. The answer is not straight and simple. A lot of individuals will say just lift heavier weights and eat a lot of protein.  To be honest, that is part of the answer, but you have to do this strategically. In this article, we are going to talk about the resistance component of increasing your muscle girth (size). Food intake is a critical variable to this equation, but that is another topic of discussion.

Gaining muscle mass for an individual who is thin and has a high metabolic rate may seem like an unsurpassable task, but it is possible. On the flip side, for an individual who is large in mass and wants to lose weight, but keep their muscle mass, this can also be challenging. As a quick rule of thumb--whether you want to lose weight or gain weight--is that you still need to feed your entire body the proper nutrients it needs to react the way you want it to. You cannot starve your body or eat too much of something because your body will react by excreting it or creating the wrong type of weight gain or loss.

The terms "getting bigger, yoked" etc. are all related to the term hypertrophy, which is a gain in muscle size. On the contrary, if your muscle shrinks in size, that is called atrophy.

Gaining Muscle Mass

In one of the old Greek tales, there was a young boy who used to carry his baby calf up the hill every day. As a young man, he was now carrying the same mature cow up the hill every day, but he was not struggling because his muscles could sustain the external resistance demanded from carrying the animal.  This is called the Overload Principle. This principle tells you that in order for your muscle to gain in size, it must be challenged with an external force that will challenge its performance. By doing this type of activity, the muscle will be exposed to microscopic tears in the tissue and it will need to repair itself, create scar tissue and react by growing a small amount of muscle mass as the reaction to this type of training.

This does not happen overnight. If you decide to work the same body part over and over again expecting that muscle to be torn down and repaired, you have another thing coming. You need to work the muscle with the various exercises, but you must let it rest so it can grow, recuperate and be ready for the next round of loaded resistance you will place on it. If you don't let it rest and grow, your muscle will be fatigued and not rested and you will succumb to injury or muscular imbalances.

Here is an example of the Overload Principle at work.

Flat Chest Press

Set 1 -- Warm up 12-15 reps with a light weight (tell the muscle what it is going to be doing)
Set 2 -- Moderate weight X 12 reps
Set 3 -- Moderate/Heavy weight x 12 reps
Set 4 -- Heavier Weight X 8-10 reps
Set 5 -- Heavier Weight 4-6 reps
Set 6 -- Light to moderate weight to burn out X 15-20 reps
*A maximum of 60 seconds between sets and no more than that.

The example that I just explained can be applied to all of the exercises you are going to do. If you are going to do incline chest bench press and flyes, this same principle can be applied to your muscles.  You must overload the muscles so that it is challenging to push the weight up, but you must perform the exercise with correct biomechanics. If you need a spotter to help you lift the weight, make sure they do not do most of the work. They are there for safety concerns and that you maintain correct form and biomechanics when performing any exercise.
