Well into her third trimester, Pippa Middleton is relying on a new form of exercise (sorry, tennis) to keep herself and her baby healthy.

The soon-to-be mom opened up about how swimming during her pregnancy has become one of her favorite workouts in her most recent column for Waitrose, and debuted her sporty poolside style in the process. The best part? Her Sweaty Betty “Free Dive” one-piece is on sale for $84. Score!

“Swimming throughout pregnancy offers a wonderful feeling of weightlessness,” she wrote. “From personal experience, I’d confidently say I find it has been the most enjoyable and rewarding form of exercise since I found out I was expecting. It’s comforting to know that it’s safe throughout pregnancy, and you don’t need to adapt and change too much (unlike most other sports).”

Middleton went on to explain that swimming is the optimal exercise choice for women in their third trimester because it helps to offset “feelings of bloating and swelling,” and also keeps the “body cooler while exercising.”

Since being sweaty, bloated and pregnant is no one’s cup of tea, we’re filing this away for later use.
