Hilaria, who married Baldwin in 2012 and who is also mother to Carmen Gabriela, five, Rafael Thomas, three, and two-year-old Leonardo Angel, said she wants to inspire people to lead healthy lifestyles.
Along side the pictures, she wrote on Instagram: “The recovery from baby number 4 continues….I share my journey and posts here because I believe so strongly that smart exercise, good eating, and a calm mind= healthy body.
“And I want you to experience it too because life is so worth living to it’s max…and you are so worth it.”
Hilaria, who is Spanish, previously told how she wanted to “normalise the postpartum figure” by sharing a selfie the day after giving birth in May.
Baldwin, 60, also has a daughter, 22-year-old Ireland, from his relationship with Kim Basinger.
