By the time she was 22, she had completely cut meat from her diet.

Underwood now calls Nashville home, and says the vegan options are plentiful there, too.

But sometimes, she cant stick to it 100 percent.

I want to be vegan so badly, all the way, 1,000 percent, she says.

But traveling and stuff, it just kind of gets hard.

Sometimes I may have to do some egg whites or something forbreakfast, she says.

On a typical morning, Underwood likes to make a tofu scramble for breakfast.

For lunch, I love agood sandwich, she says.

Shell use vegetarian sandwich meat from brands likeTofurky, and of course,avocadois a staple.

On the side?Veggie straws, or something similar, she says.

Veggie burgers or chicken scaloppini also show up on the menu often, as does brown rice.

All my food has little air quotes around it, Underwood jokes.

She likesGardeinfor meatless chicken and beef products.

Im always making muffins or something like that to keep around.

I have snacks on me all the time.

I dont ever want to be hungry, I hatebeing hungry.

Another tip for fellow new moms out there: Wear your workout clothes all day.

I will wear myCaliaall day long and then if my son takes a nap, Im good to go.

He will take a nap, but it might not be very long.

But Im ready for it, Underwood says.

Calia is her fitness apparel line, available exclusively at Dick’s Sporting Goods, that launched in 2015.

Sometimes, hell take his nap time in the stroller, while Underwood gets a solid walk in.

He enjoys just being outside and looking around.

Its good for both of us, she says.

Recently, Underwood has been adding weights into her routine whenever she can.

Ive been getting more and more into doing more stuff with weights, she says.

I love it, she says.

I just love seeing that forward progress and I likefeeling strong.
