Betty is smart, capable, and yes, a bit chunky. Unlike, oh, Blondie, she doesn’t have an exaggerated shape. Also unlike many women in comics, she works out, plays hockey, and is quite capable at work and around the house.
I also love that in the current storyline she’s dissatisfied with her workout because…she’s tired of her current workout music. But then I walk on the treadmill while listening to music and watching TV — and it has to be a show I like. I’ll walk outside without music to distract me, but not on a treadmill.
I also sometimes bribe myself with “go for a walk and you can eat lunch out”.
