From that shot, Ruhl is much bigger, muscular. But here is the kicker. The problem with one shot it that you are not sure in the picture whether Flex is done with his pose or if he is just starting or ending. That is why there are many other poses - because someone may have the greatest chest, and the worst back and legs. Or not be symmetrical. Still, many people prefer Flex's physique because that is something attainable to them, whereas Ruhl is just out of this world. That is one of the biggest debates in the industry, whether or not a smaller framed and lower weight pro bodybuilder can get a fair shake in the face of a heavier, more muscular bodybuilder. Do you compete on muscles or symmetrical, conditioning or hardness, and so on.
