“We’re not all size zeros,” Underwood shared. “We’re different shapes, sizes, ages. It’s important to encourage people and be a part of people’s journeys, no matter where they are in those journeys.”

The “Cry Pretty” singer told PEOPLE she had to remind herself of CALIA’s empowering message after thebirth of her second son, Jacob Bryan, in January, when she felt thesocietal pressure to have her body “bounce back” right away.

“After having my first kid [Isaiah, 4], I felt like I bounced back fast. And then with Jake, it was like my body took a minute to get back to me. It was frustrating, because I’m like, ‘Why wasn’t it like the first time?’” Underwood said.

She added: “But I’m four years older. That also helped meshift my mindset— I’m still working hard, wanting to be the best me possible, but cutting myself slack and just thinking, ‘Be kind to yourself.’ It’s amazing what we [women] do to ourselves. We’re probably all our toughest critics.”
