Pippa Middleton's Waist-Whittling Workout Routine
Catch her if you can! Duchess Kate's younger sis never slows down!
Two weeks after finishing a June triathlon in Woodstock, England, Pippa Middleton competed in Scotland's Highland Cross race, a 20-mile run and 30-mile bike ride.
"She does it all: tennis, swimming and running," an insider tells Us Weekly.
But the 5-foot-9 single stunner's true love? Hourlong Pilates sessions with Margot Campbell at London's Pilates on the Go.
"I always leave feeling calm," Pippa, 28, has said of the mat- and Reformer-based workouts. "I have noticed a huge difference in my core strength."
And, of course, the sessions help form her famous body part. Reveals a pal, "The kneeling one-legged pull on the Reformer gives her bottom that pert and round shape. She takes her workouts seriously."
While it's clear that Middleton, who is the author of a forthcoming party-planning book, loves her daily caffeine fix (specifically at London's Le Pain Quotidien) to get her metabolism revving , she also "loves fish and Mediterranean food," says a source.
