Do Genetics Play a Major Role in Building Muscle Mass?

Muscle Building

If you want to get in shape and build muscle mass, it is important that you consider the role that genetics play in doing so. The fact is that getting fit is easier for some people than others. The more you understand about how genetics affect the ability to build muscle, the easier it will be for you to meet your fitness goals. There is a lot of information to get before you can start hitting the gym.

The Basics

A person’s potential for aerobic fitness is usually determined half by genetics. The amount of muscle mass a person is capable of gaining is fifty to sixty percent determined by genetic factors. Not everyone is cut out to be a professional athlete, because a large part of one’s potential comes down to certain traits that are inherited. Some people are naturally better than others at sports for this reason. Those who don’t have ideal genetic traits can still gain muscle mass, though it is usually requires more effort.

Genetic Tests

There aren’t any genetic tests that are able to determine a person’s potential for fitness with any accuracy or reliability. While it’s true that there are certain tests that claim to identify genes that are associated with fitness, they don’t work all that well. It is important that you avoid paying for any genetic testing services that can claim to tell you what your fitness potential is, because it is likely just a scam.

Scientific Research

There is plenty of scientific evidence to support the idea that genetics play a major role in building muscle mass. Hundreds of studies involving thousands of participants have definitively concluded that one’s genetic makeup is a major determining factor in their ability to build muscle as well as aerobic and overall athletic performance.

This research has been crucial in establishing the concrete idea that genetics have a huge impact on one’s fitness potential. Anyone can gain muscle, but some people simply need to work a little harder than others to do it.

The connection between genetics and athleticism was firmly established back in 2007. It was determined that there were just over 200 autosomal genes that could have a noticveable impact on one’s athletic performance and fitness potential. The ACTN3 gene is by far the most well-known when it comes to athletic performance.

Around 20% of all people are deficient in the so-called “performance gene”. These people’s bodies make extra ACTN 2 as a way of compensating for the deficiency. These are typically the people who are not predisposed to outstanding athletic performance, and it can be difficult to achieve fitness goals.

The fact is that not everyone, and in fact most people, just aren’t meant to be a professional athlete. Those who are more interested in gaining muscle, however, can always do so if they are committed enough. The more time that you set aside for getting in shape, the more likely you will be to accomplish your fitness goals.

Beating the Odds

Even those who are somewhat genetically inferior in terms of fitness can still beat the odds to a certain extent. You will need to keep increasing the quantity of sets that you do each week so you can maximize your potential to gain muscle mass. Those who are just starting out will want to make a point of doing a few sets of the exercises of their choosing. This can help with building muscle mass regardless of genetics.

Creating an Effective Workout Schedule

Your workout schedule can make all the difference when it comes to building muscle. Those who have a more difficult time gaining muscle because of their genetic makeup will need to be extra careful when crafting their workout schedule. Keep in mind that you will need to give yourself a day or two of rest each week so that your body can heal. Each of your workout days should devote time to a different muscle group. You want a workout schedule that gives equal attention your legs, chest, back, arms, etc.

Genetics and Fat Storage

A lot of people struggle to gain muscle mass because they have a hard time with losing their excess fat. Genetics also play an important part in one’s ability to lose or gain weight. Some people have a hard time gaining weight, while others find it challenging to lose weight. If you want to gain muscle mass, being overweight or underweight can present a challenge if your genetics aren’t in alignment. There is also quite a bit of scientific research into this subject.

One person may be able to consume 4,000 calories each day and not gain much weight, while others gain weight quickly when consuming only 2,500 calories per day. It’s still possible to lose or gain a significant amount of weight regardless of one’s genetic makeup, but it all comes down to a question of how easy or difficult it is.

The whole idea that genetics plays a significant role in obesity has been around for quite a while. There are certain receptors in the body that relate to insulin production, and their functionality is largely genetic. Some people naturally produce more insulin than others, which can definitely affect the ability to lose or gain weight.

It’s Not All Bad News

While it may be true that genetics does play a significant role in fitness and muscle-building, there is still plenty of hope for those who haven’t won the “genetic lottery”. With some extra hard work, it is very possible for the average person to get to where they want in terms of muscle mass. Everyone has their own problems with genetics, but some people have a more difficult time than others with building muscle on their bodies.

It’s also important to keep in mind that not everyone responds equally to the same things when it comes to working out. There are some who get better results from increasing the intensity of their workouts, while others tend to benefit from working out more often.

Building muscle is largely a matter of trial and error for a lot of people. There is typically a limit when it comes to just how fit a person can get, depending on their genetic makeup. But there is always hope for building muscle no matter what your genetics are like, as long as you are patient enough and take the right approach. This trial and error stage can be frustrating for a lot of people, but it is often necessary.


There is no question that genetics is a significant factor in gaining muscle mass well as overall fitness and athleticism. You will find that there are a lot of things that ultimately determine how quickly and efficiently someone gains muscle, including how often they work out and how hard they push themselves. If you want to gain muscle mass yourself, you shouldn’t get too caught up in genetics. Some people do have an edge over others because of their genetic makeup, but anyone can gain muscle if they are dedicated enough to doing so. Genetics are just one piece of the puzzle when it comes to getting in shape.
