It is a coincidence that Deepika Padukone and Katrina Kaif share a common gym instructor. With numerous theories doing the rounds on which is the best hour to work out, the gym lady says that the Bollywood divas have their time preferences. Deepika, who is a morning person, usually hits the gym as early as 6 or 7 am. Kareena Kapoor Khan likes a midday routine of yoga and exercise, so she is comfortable starting her workout routine at noon. Katrina, on the other hand, likes to keep it flexible. She hits the gym as per her convenience. “It could be anytime between 4 pm and 7 pm or even at midnight,“ says our source.
