Here's an interesting little blog entry I just stumbled across:http://fitnessblackbook.com/main/tarzan-vs-conan-a-competition-of-the-ages/
It makes some good points. For the real Conan fans, though, it's important (and only fair) to note that this article describes the character as most people envision him today, thanks in large part to comic book and film versions of the past couple of decades. As Robert E. Howard described him, though, Conan of Cimmeria stood 6 feet, 2 inches tall, and weighed about 210 pounds. Although nobody was ever described as being stronger than him, there were other characters who were larger. His movements were powerfully athletic and cat-like, not like those of a bloated, bumbling bodybuilder. Conan and Tarzan, as originally described, are really quite similar, physically.
