Carrie Underwood was spotted twice recently as she got back to work only five months after giving birth to her first child, Isaiah, with NHL superstar Mike Fisher.

Both times, Carrie Underwood looked absolutely amazing, even daring to show a tiny bit of midriff.

The first was on set while shooting a music video wearing a white shirt with a little peek-a-boo at the bottom and sky-high brown boots.

Carrie Underwood, a day earlier, was at the Watershed Music Festival in George, Washington. She looked relaxed and casual in short shorts and a t-shirt.

Oh, there must be something in the "Watershed!" I know…lame joke, but, seriously, thanks for having us out at The Gorge for the Watershed Festival! That crowd…that view…amazing!

So what is Carrie Underwood’s secret? Is it the happiness and glow of being a new mom? It seems their new little family is trucking right along and taking baby on the road.

My boys…checking out the world through the bus window.

Could it be marital bliss? Well, her relationship with her husband does include some together time in the home gym.

The couple that slays together…stays together! Working out is always better with a partner! #StayThePath

It’s actually pretty simple. Carrie Underwood is just always ready to jump on the opportunity to work out.

She told ET, “I was healthy throughout my pregnancy — as healthy as I could be. I definitely splurged more than usual, but I just started getting back into it afterwards.”

She added, “I make workouts happen wherever they need to happen. [Isaiah] falls asleep … and I’ll just go do [a workout] real quick!”

What do you think of Carrie Underwood’s quick transformation?
