Its strange, depending on where you live often dictates what people aspire to look like and what women find attractive. Living in England I found that generally, due to the climate very few people worked out seriously, there were exceptions, like Rugby players, but generally few in England have muscle. In fact there are a whole lot of shapeless people over there! So being slim, and lean is often a desired build, like a David Beckham body for example.
Coming to Perth Australia though I found everything completely different. There is year round sunshine and beaches, also Aussies are so into fitness and outdoor activity. Also here the sports are Australian Rules Football and Rugby where the build is muscular and large. So everyone I know of my age hits the gym in a big way, because you need the muscles here for the girls! In England I was about 170 pounds, now I'm about 210 and big into weights and the gym. When I go to England I feel big and athletic, but here I am just the norm.
