I have to summarize this:

Somatotonic Mesomorph. If a man is definitely a broad type rather than a thick or long type, he is likely to be rugged and have lots of muscle. He is apt to have big forearms and legs, and his chest and belly are well formed and firm, with the chest bigger than the belly. He would rather breathe than eat. He has a bony head, bit shoulders, and a square jaw. His skin is thick, coarse, and elastic, and tans easily, If he gets bald, it usually starts on the front of the head.

Here is my summary:
The summary for this paragraph talks about how if a man is a broad type then he is big all around except for his upper body which is small. He would also breathe than eat. Also, his head becomes bald.

Is this correct

Read it again. His upper body is small? "He is apt to have big forearms and legs, and his chest and belly are well formed and firm, with the chest bigger than the belly." Either you mis-read it, or your reading comprehension is very, very poor.
