Shakira gave birth to her son Milan just three months ago, and she's already dropped 30 pounds! Her trainer Anna Kaiser tells Life and Style, Shakira is incredibly smart and very focused when it comes to working out. She loves to make her workouts as efficient and effective as possible. The key is Anna's AKT In Motion workouts, dance-based cardio combined with cross-training. Plus, it doesn't hurt that Shakira was already in the best shape of her life, living on a clean diet of lean protein, fresh veggies and limited fat.
