The 42-year-old actress, who is expecting her first child with husband Jose Antonio Baston, took to Snapchat on Friday to show of her prenatal workout -- which was no walk in the park.
Longoria made her way around the gym, getting her steps in on a treadmill before lunging with a medicine ball and working with hand weights. "Omg everything is so hard!" she wrote alongside a post, but was all smiles with her trainer, Salvador Garayzar.
Longoria's rep confirmed her pregnancy to ET in December, revealing that she and Baston are expecting a baby boy. This will be the fifth child for Baston, who is dad to daughters Natalia and Mariana and sons Sebastian and Jose, from a previous marriage.
"New year, new adventures! I’m so grateful to my beautiful family for giving this new baby so much love already! ?? #HappyNewYear #2018," Longoria captioned her first Instagram pic of her baby bump on Jan. 1.
