I was going to say your dad IS mega dedicated, but he's what should be normal.  Still, good for him. My wife is currently very pregnant and whenever she complains about something being hard due to her size (and there are hams around) I make some comment about how "yeah, I bet you're glad you're not always this big, I mean could you imagine being this big or even bigger ALL THE TIME just because you ate too much?" Gotta be careful with wording because pregnant lady feelings are something you have to coddle very, very carefully, but you probably get the point. As for Curves, apparently they have this 20 minute circuit that you're supposed to do once and only once.  It's a bad joke.
