"As I begin the final trimester of this pregnancy, I feel my body slowing down," she wrote in the caption. "I love exercising while pregnant and feel grateful that my pregnancies have allowed for me to be active."

Nonetheless, Hilaria said she appreciates the phases of her childbearing years.

"Respecting the slowing down process and then the slow rev up again after baby. The expansion and contraction of the body. How grateful I am to have these experiences in my life's story," she said.

She also poked fun at her past self in the video for exercising in sky-high heels, saying, "You guys know me: always moving around with whatever I am wearing 😂."

Hilaria and her husband Alec celebrated their 10-year wedding anniversary this year.

The couple's new daughter will join big sisters Carmen and Maria Lucia Victoria, 16 months, as well as brothers Rafael Thomas, 7, Leonardo Ángel Charles, 5½ , Romeo Alejandro David, 4, and Eduardo "Edu" Pao Lucas, 22 months. Alec is also dad to daughter Ireland Baldwin, 26.

At the time of their pregnancy announcement in March, the Baldwins told PEOPLE, "We have 'somos un buen equipo' engraved on our wedding bands. We say that to each other all the time at home — that we're a good team. One of the most beautiful things my children have experienced with a big family is how the heart can grow with every new sibling."

"Our capacity to love continues to expand and we can't wait to embrace our new little one this fall!" they added.
