Pippa Middletonis soaking up the sun thisChristmasseason.

The 36-year-old sister ofKate Middletonenjoyed a holiday getaway to St. Barts, where she was snapped on Wednesday alongside husbandJames Matthewsas the two spent Christmas together on the beach.

Pippa, whose mom Carole was also along for the trip, showed off her abs in a white bikini with a playful polka-dot design. Her financier husband, 44, opted for a pair of blue swim trunks featuring a beach landscape print. Both carried goggles in their hands.

While it’s unclear exactly where the couple were taking a dip, James’ parents, David and Jane Matthews, own the French-speaking Caribbean island’s first (and still one of its finest) hotels,Eden Rock.

Pippa and James have vacationed in St. Barts multiple times over the years — including just 10 weeks after they welcomed their first child, now-14-month-old sonArthur Michael William, when the new mom was photographedhitting the beach in a white two-piecewith black stitching.

From grueling marathons to downhill ski races, Kate’s younger sister is famously athletic, having kept up a tireless workout routine over the years. And herdedication to fitness continuedthroughout her pregnancy.

“When I learned the happy news that I was pregnant, I realized I needed to adjust my four to five-day-a-week [fitness] routine,” Pippa wrote in January in her column for the U.K. supermarket monthlyWaitrose Kitchenmagazine, noting that she kept her pregnancy a secret from her gym instructor until the “riskier months” were over.

“This being my first pregnancy, I had so many questions I felt were still unanswered,” she said. “I wanted to know things like, would I strain if I served in tennis, are strokes of swimming safe, can I still do a normal yoga class if I avoided certain positions? Could I still work my abs?”

Pippa continued to swim, play tennis and keep up with her barreworkouts during her pregnancy, writing, “It’s comforting to know that [swimming] is safe throughout pregnancy, and you don’t need to adapt and change too much (unlike most other sports). It’s so good for you that you could swim every day — as long as you don’t overexert yourself — right up until the end of the third trimester.”

Pippa explained thatin addition to free play, there are classeswith “structured activities that help promote movement, balance and strength.”

“Arthur burns lots of energy in this safe environment and learns many physical skills,” the mother of one said. “I have also noticed him building his confidence with each visit.”
