Kate Middleton takes her fitness fetish to Clarence House

Prince William's girlfriend, Kate Middleton, has had a well equipped gym installed at Clarence House, the royal home in London on the Mall that is the official residence of The Prince of Wales, the Duchess of Cornwall, and the Princes William and Harry.
Since being given access to it, Kate, spends most of her time at Clarence House, though she continues to own an apartment in Chelsea where she lives with her sister Pippa.
"Kate has all her things there and asked William and Harry if they would allow her to build a gym," a Royal aide told Daily Mail
"She works out for at least an hour a day and loves to stay slim and toned. She and Pippa use the gym all the time because it has great equipment and it's completely private.
"She has even had William and Harry doing crunches and press-ups.
