Do Black People Have Better Genetics For Building Muscle? Is it true that race can influence muscle size?

For a long time people in the bodybuilding circles have been talking about “black men’s muscle genetics“. There is a belief that having African roots is beneficial to building large amounts of aesthetic muscle mass.


Whenever people post a picture of a muscular man who happens to be black the usual response is:

“He is black. He can gain muscle while playing cards and eating donuts all day.”

Is this really the case? Are black people that incredibly gifted when it comes to building muscle mass?

It’s Not About Race. It’s About Personal Muscle Genetics.

It’s true that a large majority of the black community is gifted in the field of athletics. This is backed by the fact that almost all top level running athletes are black.

Without a doubt there is a thing such as “black men’s genetics” because if there wasn’t, white people and Asians would also be setting world records in the sprints disciplines. This part of the sport sector has always been dominated by black people and it doesn’t look like the hegemony will end in this lifetime.

The fact that black people are good at fast and explosive sports such as sprinting has a direct effect on bodybuilding since both activities rely on fast twitch muscle fibers. Unlike slow twitch fibers, fast twitch fibers have more potential for muscular growth which explains why people with predominant amount have larger musculature.

However, there are “highs” and “lows” in every community. Some black people really have good genetics for building muscle but there are many who don’t exactly excel in the muscle game.

The fact that you’re black does not mean that you have superior genetics for building muscle mass by default. Muscle size depends more on your personal genes rather than race. You can be black and suck at bodybuilding or even basketball for that matter. You can also be from a different race and excel. There are no guarantees.

The Slave Period

A lot of people attribute black men’s muscle power to the slave period when blacks were forced to work day and night and therefore “only the strongest were allowed to survive”.

Of course, this is true – only genetically healthy and strong people can endure similar torture. The weak fail to answer the requirements and were therefore left for dead in miserable conditions. However, it would be naive to think that black slavery has altered the genetic pool so much.

There were slaves from all kinds of races in human history. At one point representatives of every race were conquered by a stronger country and forced to do the hard work. Every nation has a tough history.

It’s genetics. What are you going to do about it?

In the end of the day genetics are genetics and cannot be changed. We all have to work with what we have. The color of your skin does not mean that you will be able to build muscle more easily even though many black people are genetically gifted athletes. Whatever your case is, don’t overthink and focus on the things you can actually affect in positive direction.

    I think blacks are better for muscle building and whites are better for strength. Most of the powerlifters are white people. You don’t see any black domain in powerlifting and see in bodybuilding. Simples as that.
    Black = size
    White = strength

    Such a baseless argument. I’m an African and not muscular like you think. White black or Asian we are the same.
