Katherine Schwarzenegger enjoyed a day of horseback riding with mother Maria Shriver and daughter Lyla in tow.
The 32-year-old author showed off her postpartum figure in a streamlined black outfit six months after giving birth to her second child with husband Chris Pratt, 43.
The trio spent time getting some fresh air in the Los Angeles sun while Maria tended to the toddler.
Katherine, who has written several self-help books, wore knee-high riding boots and a black helmet.
She tied her dark hair back in a low, messy bun as she mounted a bay stallion.
Maria, who was married to Arnold Schwarzenegger for 25 years, wore dark blue jeans and a patterned top.
The journalist’s long-sleeved blouse was partially transparent and buttoned.
She was a doting grandmother while keeping a wary eye on her granddaughter, who was dressed in pink.
Shriver pulled her blonde-streaked hair back from her face with a clip, leaving the back part loose.
The news anchor covered her eyes with slim, rectangular sunglasses and carried her phone in a red tote bag slung across her torso.
The young woman’s curly blonde hair flowed out of a white bucket hat as she watched her mother participate in the outdoor activity.
Earlier this month, Katherine showed off her toned abs in a new sports bra collab.
She showed off her impressive abs as she donned a black sports bra underneath a loose-fitting blue shirt that fell off one shoulder.
“So excited to team up with @itsbodily to introduce the Katherine x Bodily Bra and join Bodily as Chief Bodily Advocate!” she wrote in an Instagram caption.
‘Join the CEO of Bodily on today’s edition of BDA Baby at 12pm PT to learn more about this exciting launch!’
Schwarzenegger married Pratt in June 2019, just a year after they met.
The two began their romance following the actor’s divorce from Anna Faris, whom he married in 2019.
As well as daughters Lyla and Eloise with Katherine, Chris also shares 0-year-old son Jack with his ex-wife.
Last month, the author told Us Weekly that she’s ready to have more children.
“I come from a big family, so I love the idea of having lots of kids and a big family,” she said, adding, “Whatever God has in His plan for us, that’s what we’re going to do.”
