In the 1940s, University of Houston professor William Sheldon created the concept that all humans belong to one of three body types, or somatotypes.

It was bold. It was revolutionary. That was complete nonsense.

the whole concept of a Available in all three sizes The classification system has never been supported by science. In fact, it has been almost abandoned since its introduction. But that did little to slow the flow of misinformation, which Sheldon said was largely based on personal observations.

Just in case you've forgotten or are fortunately unaware of this classic piece of junk science, a brief review may be in order.

What are the 3 body types?

Like us, you likely learned about the three body types in middle school health class. And on the surface they probably seemed pretty reasonable.

ectoderm

Their physical appearance is described as long and slim, with a thin waist and low body fat or muscle mass. Gaining weight can be difficult, but losing weight is relatively easy. Imagine Zoe Saldana or Bruce Lee.

endomorph

According to Sheldon, endomorphs have an abundance of body fat and muscle, which makes it easier for them to gain weight, which in turn makes it more difficult for them to lose weight. Think Serena Williams or Chris Pratt here. parks and recreation).

mesoderm

Mesomorphs are characterized by being athletic, hardy, and strong. A napper that falls between the other two body types. Let's go with Mark Wahlberg or Alex Morgan.

Are body types real?

Again, Sheldon's somatotype is inaccurate and oversimplifies the human body.

“Few people fit perfectly into one of the classic body types,” says Trevor Thieme, CSCS. “Most people are a hodgepodge of them. For example, the upper body may be 'mesomorph' and the lower body may be 'ectomorph'. But being able to categorize body types doesn't really matter. Because body type doesn't necessarily tell you what you do. respond to training.”

So why is this like this? fitness myths Hard to get rid of?

“I think it has a lot to do with the fact that most people want easy solutions when it comes to fitness and fat loss,” says Thieme. “And this gives us the idea that if you have X body type, you should focus on Y exercise type.”

But that thinking is backwards, Thieme says. “You must Start with your goalsBecause this will shape your training program regardless of your ‘body type’.”

Can I change my body shape?

Somatotype does not predict training response. That means there's a lot you can do. change your body composition. And it can actually be quite liberating to start with your goal (e.g. building muscle) and then work backwards to determine the optimal training plan.

This means that if you're a classic ectomorph, you don't have to prefer running the streets. pumping iron. And if you're an endomorph, there's no reason you shouldn't train for a marathon if it's on your bucket list.

The important thing here is that you will never know what you are capable of until you try. But it's important to know what you can control and what you can't.

The Role of Genetics

To be clear, just because your body type doesn't predict performance doesn't mean your training is of a high standard. Regardless of your goal or the route you take to get there, you'll likely encounter others traveling faster or slower than you. Because what's written in your DNA still matters.

“There are many factors we can manipulate to our advantage depending on our goals, including training frequency, training intensity, which exercises we prioritize, and programming. periodizationNutritional factors — but it’s also important to understand that some people choose the right parents.” Tony GentilcoreCSCS, is the owner of CORE, her own training studio in Brooklyn, Massachusetts.

“Some people grow taller just by looking at dumbbells. Some people need to fight and exercise desperately. many “It’s to see the fruits of their efforts,” he added.

The most important factor in choosing exercise

And that applies regardless of the ultimate goal. “But at the end of the day, what ‘works’ is what you actually want to do and stick to consistently,” says Gentilcore.

So tailor your training to your goals, exercise preferences, time constraints, and strengths and weaknesses, advises Thieme. “Your training plan should be tailored to you as an individual, not based on body type categories that were not created with exercise in mind.”

History of body types

Sheldon doesn't even categorize body types for fitness purposes. He was a psychologist who determined that attachment was possible. personality characteristic By body type. He was more interested in how our bodies shape our personalities than how our bodies actually function.

Sheldon hypothesized that the appearance was introspective, artistic, and emotionally intense. Endomorphs are cheerful, relaxed, and sociable. Mesomorphs are assertive, adventurous, and competitive.

If that sounds like poppycock, balderdash, or some other 1940s word for bull effluvium, it turns out that Sheldon's entire motivation for research was completely false.

According to a 2015 article, "Sheldon's toxic eugenics views and equation of physique with fate made him increasingly unpopular in the years following World War II." Canadian Medical Records Bulletin. “The task of ending his career was handled by his former female secretary, Barbara Honeyman Heath. Publicly denouncing his methods as fraudulent and his somatotyping inaccurate, she went on to refine her somatotyping techniques and build a successful career working on projects around the world.”

Why do body type myths persist?

That kind of heavy beating from the medical and fitness establishment led to Sheldon's idea of ​​three major body types: Segway, Zune, New Coke, and Cheetos Lip Balm (Yes, that was a real product).

But as a quick Google search will show you, body type myths are surprisingly powerful. To give one of too many examples, London's daily mail “Scientists say we all fall into three groups (and knowing your body type is key to choosing the right exercise),” the paper claimed.

The three-body type theory gained so much attention so quickly that it soon became accepted conventional wisdom and has remained so ever since. Like the zodiac, somatotype analysis works because almost anyone can find their own characteristics in almost any “personalized” designation.
