The trainer, who was previouslyopen about her decision to exercise while pregnantwith Athena, tells PEOPLE she again aims to stay active during her pregnancy and hopes to continue to change the stigma that expecting mothers are limited when it comes to working out.

This time around, Arzón says she feels she better understands the importance of “protecting my peace and really owning my no” during the pregnancy journey.

“I think having patience with the process is important,” she says. “There’s such a surrender to motherhood that there are just so many things that you can’t control. So that’s why focusing on the little things that I can control and the moments that give me peace and light my fire are super important.”

“So during pregnancy, I find that it’s even more important to carve out time for my workouts and even more important for me to focus on sleep and fuel and protecting my peace,” Arzón continues. “I want to feel like myself as much as possible when there are plenty of days where my body is just doing its own thing.”

As Arzón looks ahead to her “original wolfpack” becoming a family of four, she says she’s excited to see “new bridges and relationships being made.”

“Athena has such a unique relationship with every single person in my family. And it’s going to be really cool to see that grow with another human who has their own personality and their own soul mission,” she shares.

“It’s really neat to be able to weave an incredibly rich fabric in the tapestry of our family legacy,” adds Arzón. “I find that really powerful.”
