I think of Billie from David Willis‘s Dumbing of Age as a girl who was pretty fit in high school simply because she was a cheerleader and they work out all the time because they have to. Cheer practice? Exercise. So now she’s in college and we see her starting out with the Freshman 15 because what did she do all summer? Not cheerleading, that’s what.
Of course, maybe she was always a little chunky and that’s cool too. There’s just an awful lot of gymnastics in most actual cheerleading and that stuff is hard.
