Married life is "a lot like dating," Underwood, 27, tells Women's Health for its October issue. "Sometimes our schedules will click, sometimes they won't. But that's good because we're both independent."
One place where they manage to spend time together: at Fisher's hockey games in Canada, where he plays for the Ottawa Senators.
"I love going to games, cheering for my man," Underwood says. "When I come home, I'm accused of picking up the [Canadian] accent."
Underwood keeps her routine low-key, and says she's not the type to be caught in a Lindsay Lohan or Snooki-esque situation, because "I'm not the kind of person who does crazy things.
"I'd sleep in a little, work out, do laundry, run errands, buy presents for people with birthdays coming up," she says. "I like it when I don't have to be anywhere, and anything to do is my choice."
Her regular workouts have given the country singer-songwriter at least aspect to her body that pleases her. Says Underwood: "I think my legs are my best asset."
