Hilaria Baldwin has hit the trail running  – literally – just one week after welcoming her third child, son Leonardo.

The mom, who is married to Alec Baldwin, shared a photo after her “first run back,” to Instagram on Wednesday.

In the image, Baldwin, 32, wore leggings and a sports bra, showing off her abdominal region.

“Getting up and staying active gives you a lot of energy,” Baldwin wrote in the caption. “Sluggishness begets sluggishness (unless you really just need to rest!).”

The yoga instrutor insisted that not every new mom can return to a workout regimen so closely after giving birth, noting, “that is between you and your doctor… as it is between me and mine.”

“This post is for those of you who want to begin a workout (man, woman, kids, no kids…) and it seems daunting,” she continued. “I gave myself the goal of 5-10 min to jog. I surprised myself and did 23 minutes. I feel great and refreshed.”

Baldwin noted that when she returned from her nap, Leo and son Rafael, 14 months, were napping, and daughter Carmen, 3, was at her preschool, which she attends “for a few hours, a few times a week.”

On Monday, Baldwin also documented her post-baby figure on the social media site while celebrating Leo’s first week on earth.

Of her “little man,” she wrote, “He is eating like a champion and gaining weight!!”
