We always knew women could never build muscles, at least not, uh, real women. Muscles belonged on men, and women didn’t want any. They didn’t need them, either, not for typing 70 words a minute, not for staying at home all day baking cakes for honeybun. But we also always knew women could never run marathons, and now we have Grete Waitz breathing down Bill Rodgers’ neck. Even more unexpectedly, we have Laura Combes’ sensational double biceps pose.
