Kate Middleton’s fitness secret

Kate leads such an active lifestyle, her diet of low GI carbs only serve to help maintain her slim frame while muscle definition is down to her choice of exercise.

She is a keen gym bunny and does at least one hour every day, using the private facilities installed at Clarence House.

Her favourite high-energy workout includes rowing, running and weight lifting. She also cycles regularly, balancing her cardio workouts with yoga sessions to improve flexibility.
