Just askher fansonTwitter, some of whom use her legs for their ownfitness motivation.

But it isn’t just great genes that have left Underwood with her now-iconic legs.

“It’s really a lifestyle for her.

In 2013, Underwood chatted withWomen’s Healthabout her latest fitness discovery Tabata.

“When I do abs, it hurts.

But I like it.

It makes me work.”

The mama-to-be didn’t let her baby bump become an excuse for skipping out on the gym.

“She’s a champ!

“Erin Oprea, who trained Underwood during her 2015 pregnancy, toldPeople.

And not much changed from Underwood’s pre-baby bump workouts to those she did while expecting.

“I’m looking forward to reclaiming my body,“a pregnant Underwood toldPeoplein 2015.

“I’ve been saying it’s been on loan for the past many months…

I’m excited to take it back.”

And she hasn’t let motherhood stop her.

Besides weights and mixing up her intensity training, Underwood also enjoys going for long runs outdoors.

“It’s the thing I do for me.”

Underwood wrote that she was healing, but “not quite looking the same.”
