When you're the star of one of the highest rated shows on television, you have to keep yourself in good shape for the cameras.

And Kim Kardashian certainly takes care of herself, if her hourglass figure is anything to go by.

The reality TV star paid a visit to a Sherman Oaks gym this morning in Los Angeles, wearing skintight black bottoms that emphasised her every curve. Kim kept her famous derriere under wraps with a black shirt. She almost succeeded.

According to the Hollywood Reporter, Sunday night's episode was the E! network's highest-rated and most watched season opener ever and the network’s second most watched telecast ever.

With such a huge audience following Kim's every move, she has to take constant care and maintenance of her much-envied body.
