Carrie Underwood Says Mike Fisher Will 'Definitely' Miss Her During Tour

In a new Instagram video posted on the country singer's page on Monday, the mom of Isaiah, 11 months, wears a bright colored tank top with black shorts and exercise gloves. As she takes on different aerobics, Underwood uses a towel that comes from fashion line Calia by Carrie.

Underwood mentioned that if someone has towels like this as well as a smooth ground, then a good workout can happen. And based on the way she presents herself, it appears that the star is getting all the energy she needs.

Is Carrie Underwood Planning On Having More Children?

The country icon has been married to Mike Fisher for more than five years now. Speaking to Britain's Hello! Magazine, Underwood mentioned that she and her husband didn't expect to have a boy upon finding out she was pregnant. But that didn't stop them from feeling just as overjoyed.

"When we discovered we were expecting a healthy baby boy we were so excited," Underwood said via Belfast Telegraph. "I wouldn't change him for the world. He's perfect and where before I couldn't imagine my life with him, I now can't imagine life without him."

She also revealed that it will probably be a while before she has any more children.

"I'm still figuring out how it will be when I take him on tour with me next year and when I have more children," she said. "I have to be with them; that's not negotiable. We'll probably be figuring our way through this."
