Kourtney Kardashian at Miami Beach

"Kicking off the day with some vigorous exercise, Kourtney Kardashian took to the sands of Miami Beach this morning (September 27).

Joined by some hunky friends, the “Keeping Up with the Kardashians” babe went for a run and also performed squats and lunges as a way of working off her pregnancy weight."
