Pippa's fabulous post-baby figure comes as no surprise, as she has spoken publicly about keeping fit during her pregnancy. Writing in her Waitrose Magazine column, Pippa said: "Sport and exercise has always formed part of my daily life, from gym sessions to weekend runs, ambles or training for an event. Fitness gives me energy and helps clear my mind. I love the endorphins and the buzz factor that exercise gives."
