A little more on "Body Types" - not just three.
"If we take a tour of Sheldon's body type diagram, the endomorph's silhouette looks like a pear. Further up north we meet the endomorphic mesomorph. His abdomen is not quite as massive. His shoulders are bulkier, and this creates a rectangular shape. Much of the softness of the endomorph is gone, replaced by a feeling of solidness. The endomorphic mesomorph is like a bull. Once we hit the extreme mesomorphic pole the bulk of the abdomen has dwindled even further, and there's a strong contrast between the relatively narrow waist and hips and the powerful shoulders and arms. Going down the other side towards the ectomorphic pole we have the ectomorphic mesomorph. He is less heavily built, but still muscular. His neighbor to the south has an equal measure of mesomorphy and ectomorphy, making him thin and muscular. Then comes the more extreme ectomorph, and between him and the endomorph, the ectomorphic endomorph, who is perhaps the hardest to recognize. He is spread out and round without being muscular. In the middle are mid-range physiques well endowed with all the basic elements. And somewhere in this panoramic rainbow of physiques is you. Can you find yourself?"
I have arbitrarily numbered each type. Which are you? I find myself closest to an endomorphic mesomorph. Others?
