Your general shape and physique is impacted by your body type. In this article we’ll be taking a look at the 3 somatotype categories, so you can workout which body type you are.

Body Shape Explained

The shape of your body is determined by the structure of 3 things:

  • Skeleton
  • Muscle
  • Fat

As you grow up from a child to an adult our skeletal system will change and develop. Once you reach adulthood your skeleton will stabilise.


The word used to describe the shape of the human body, its structure, muscle mass and fat mass is somatotype. Every person conforms to one of 3 body types.

In the 1940s, Dr W. H. Sheldon developed the 3 somatotypes categories, allowing us to define the body shape we are by our characteristics.  With an understanding of the different characteristics that define a body type, you can workout what you are.

The 3 body types are as follows:


If you’re an endomorph then you have a heavy body characterised by the following features:

  • Round head
  • Wide hips and shoulders
  • Pear shaped body
  • High muscle and fat mass
  • Heavyset and can gain weight easily
  • Most fat is stored on the upper arms and thighs

An endomorph will be good at sports like weightlifting or powerlifting because they are strong, powerful people. This makes endomorphs great at activities that require power and strength, rather than speed or agility. Endomorphs react well to strength training due to the fact that they can increase muscle mass and overall strength quickly. The flip side of this is that endomorphs ca gain fat quickly if they do not exercise on a regular basis and watch what they eat.

If you’re a mesomorph then you will have the following features listed below:

  • Square shaped head
  • Wedge shaped body
  • Broad shoulders and narrow hips
  • Low body fat
  • Muscular physique

Mesomorphs have a good blend of strength, speed and agility. With a medium build, a mesomorph can increase muscle mass and strength quickly when training regularly. They are well suited and can try their hand at pretty much all sports. The fact that mesomorphs have a low body fat makes it easy for them to lose weight.

Resistance and cardiovascular training are well suited to mesomorphs, as they are able to maintain a lean, muscular physique with a low body fat percentage.

An ectomorph can be identified by the following features:

  • Triangular head
  • High forehead and narrow chin
  • Narrow shoulders and hips
  • Thin arms and legs
  • Little fat or muscle mass

Ectomorphs are characterised by their long, thin bodies, which are perfectly suited to endurance sports such as long distance running. With a thin build, ectomorphs will struggle to put on large amount of muscle mass and improve their overall strength. They will generally have a lean physique, but it will not be muscular.
