Upper middle class jobs are almost universally desk jobs, even in industries that have a lot of physical activity, e.g. building engineers vs. construction workers. When you sit 9 hours a day you need to hit the gym or diet. When I was waiting tables and bartending in college (and a lil after) I didn't need to workout -- a doubleshift on my feet kept me very lean. When you have money and a real need for activity then yeah the gym lifestyle becomes a thing.
