Male Body Types Explained: How Genetics Shapes Your Physique

While some men may look similar in terms of their build–their physique, form, and body type will vary. Some men naturally have broader shoulders, while others can have thicker forearms. These unique features can be defined after puberty, but exercise, diet, and even lifestyle can introduce lasting changes.

That’s why in fitness and bodybuilding, we recognize the three most common male body types: ectomorph, endomorph, and mesomorph. Understanding your type will help you learn what workouts and diets are best for you.

Read this article and fill out the quiz to help you understand your body type and how this information can help you optimize your workouts and nutrition!

Key Takeaways

• Ectomorph: Lean and slim, struggles with muscle gain due to a fast metabolism but excels in endurance activities like running and needs a higher calorie intake to build muscle.
• Mesomorph: Naturally muscular and athletic, easily gains or loses muscle, with a balanced physique suited for varied fitness routines.
• Endomorph: Broader build, tends to gain weight easily due to a slower metabolism but benefits from cardio and strength training to improve body composition.

What Are the Three Male Body Types?

Male body types can be divided into ectomorph, endomorph, and mesomorph – all having their unique features. To see how each of them differs, have a close look at this male body types chart:

❗The above classifications provide a general picture of male body types. However, you may find out that your features don’t fit perfectly into a single category. Your unique physique may have a mixture of traits, with one body type being more dominant.

History of Male Body Typing

Dating back to the 1940s, the psychologist William Herbert Sheldon came up with three somatotypes we know today. While we find these male body types useful in fitness and bodybuilding, they served a totally different purpose in the past.

Sheldon conducted research to connect certain body shapes to personality traits–an idea that has long been discredited, except for the grouped physical characteristics.

Despite the lack of scientific evidence, Sheldon’s classification system is commonly used in fitness and bodybuilding communities to help understand the best ways for weight loss and muscle gain.

That being said, you can use the Heath-Carter formula, a more scientific and modern approach to determine your male body type. It is based on the following measurements:

• Height
• Weight
• Skinfold thickness (mm) at the back of your arm, shoulder, calf, and wait
• Bone widths (upper arm and leg bones)
• Muscle girths (corrected for subcutaneous fat)

Ectomorph Body Type

• Tall and slender
• Trouble gaining weight
• Long and slender arms
• Narrow pelvis and low body fat

🏃Ideal exercise: Cardiovascular

🍛Ideal diet: High-calorie

Men with an ‘ecto’ or ectomorph body type tend to be thin and lean and have trouble gaining weight. A good example of an ecto is a professional swimmer or fashion model.

The ectomorph is relatively linear in shape with a delicate build, narrow hips and pelvis, and long arms and legs. As an ectomorph, your skeletal form and musculature are clearly evident.

Ectomorphs also tend to have less fat and muscle mass than individuals with other body types. While characteristically lean, ectomorphs should be concerned with maintaining a strong stature due to their smaller bone formation and weaker joints.

🎭Fun Fact: Some celebrity ectomorphs are Brad Pitt and Zac Efron.

Nutrition Advice for Men with Ectomorph Body Types

Keep in mind that these body types for men are rough descriptions, and there is no ideal diet plan. However, knowing that ectomorphs usually tend to have a faster metabolism and lower insulin sensitivity due to low body-fat percentage, the approach to food should be similar to:

• Eating more nutrient-dense foods
• Avoid skipping breakfast and introduce a second breakfast and even lunch to pump up the calorie intake
• Increase the intake of carbohydrates
• Opt for higher-calorie foods (e.g., banana, cheese, avocado, rice, etc.)

Workout Tips for Ectomorph Body Types

Ectos are great at cardiovascular and endurance training. You’ll find the best balance in your workouts by combining the following:

• Aerobic: Swimming, cycling, rowing
• Cardio: Running, HIIT workouts, jumping rope
• Resistance training: Deadlifts, squats, bench press, pull-ups

If you’re not sure where to start, I recommend trying out this 30-minute cardio exercise. Stay consistent and dedicated to your fitness goals, and you will soon be able to ensure any training!

Endomorph Body Type

Short and curvy

Hourglass body shape

Store body fat in the stomach or legs

Increased risk of medical issues

🏋️Ideal exercise: High-intensity training

🥦Ideal diet: Filling low-calorie food

Endomorphs tend to be shorter, stalkier, and curvy, like an hourglass. Comparatively, men with this body type tend to store their body fat predominantly in the lower abdomen, hips, and thighs.

Most endomorphs share a blend of features from both of the other body types as well. An endomorph typically has a high-fat storage capacity and tends to gain weight the easiest. While everyone’s body is susceptible to becoming obese, endomorphs have an increased incidence in comparison. Structurally speaking, endomorphs tend to have small to medium bones, shorter limbs in relation to trunk size, and less-defined musculature.

🎭Fun Fact: Celebrity endomorphs are Tom Hardy and John Goodman.

Nutrition Advice for Men with Endomorph Body Types

It’s a common thought that endomorphs have a slower metabolism and a big appetite. Is that true? Not exactly, because a lot depends on the individual’s genetics. It’s also believed that men with endomorph body types have larger stomachs, meaning they are more likely to consume large amounts of food than other men in other categories.

If you have an endomorph body type, this is what your diet should look like:

• Low-calorie food
• Nutritious and filling
• Food rich in micronutrients

Workout Tips for Endomorph Body Types

Men with endomorph body types would benefit from cardio in order to lose unwanted weight. Having said that, cardiovascular exercise may be quite strenuous on endomorphs. Hence, they will do exceptionally well with high-intensity workouts:

• HIIT (High-Intensity Interval Training): Burpees, mountain climbers, jump squats
• Strength training: Bodyweight exercises (push-ups, lunges), kettlebell workouts
• Cardio: Rowing, incline treadmill walking, cycling

Mesomorph Body Type

Lean, muscular build

Rectangular shape

Thick bones and muscles

Well-defined chest/shoulders

💪Ideal exercise: Strength training

🥩Ideal diet: Protein-rich diet

Lean muscular builds are a hallmark of the mesomorph or meso body type. Men in this category have well-developed, rectangular body shapes.

If you have a mesomorph body type, congrats! You’ve been gifted with nice genetics because this category is known for being naturally leaner and more muscular than other male body types.

Typical mesomorphs exhibit well-defined chests and shoulders that are broader than their waistlines. The abdomen is usually well-defined, with hips of about the same width as the shoulders, and the lower body musculature is typically well-toned and defined.

On the downside, with large muscles often comes reduced flexibility.

🎭Fun Fact: When you think “mesomorph,” think of Mike Tyson and Chris Hemsworth.

Nutrition Advice for Men with Mesomorph Body Types

The diet recommendations for mesomorphs are quite standard and apply to anyone looking to improve their nutrition. Your ideal meal plan will largely depend on your individual fitness goals, such as losing fat, building muscle, or getting leaner.

• Limit the amount of processed foods in your diet
• Opt for protein-rich foods (e.g., eggs, lean meat, poultry)

Workout Tips for Mesomorph Body Types

Mesomorphs excel in increasing muscle size quickly and easily. They are also full of energy and tend to be athletically aggressive.

Having said that, even athletic and lean mesomorphs can become overweight, just as with any other body type. A sedentary lifestyle with a high-fat or high-calorie diet does have a toll on the body.

Hence, if you have a mesomorph body type, you would perform well in physical activities requiring great strength, short bursts of energy, and power:

• Strength training: Squats, deadlifts, overhead press, dips
• Cardio: Sprinting, stair climbing, jump rope
• Functional training: Kettlebell swings, battle ropes, sled pushes

I have created a good starting point for men with mesomorph body type–7 resistance training exercises. This short workout will help you stay in shape with only one piece of equipment: a stability ball.

What Determines Your Body Type?

Your genetics play a huge role in determining your body type, including these factors:

• Muscle and fat distribution
• Limb proportions
• Bone structure
• Metabolism rate
• How your body stores fat

However, there are factors that you are in control of that may have an effect on your body composition:

• Lifestyle choices
• Diet
• Exercise routine
• Sleep quality

Should Body Type Affect Diet & Exercise?

While your body type can offer insights into the best diet and exercises for your routine, it shouldn’t be your only consideration. Your lifestyle and overall health are just as important when making these decisions.

Your body type may give you an idea of what’s easier for you to do and what’s better to eat, but it shouldn’t be the sole factor in your choices.

The Bottom Line

Body shapes are determined by a combination of genetics, lifestyle, and environmental factors. While it is impossible to change one’s genetics, lifestyle and environment can be modified to impact one’s body shape. With the right combination of exercise, nutrition, and lifestyle, people of all body shapes can improve their health and well-being.
