Kim Kardashian is not waiting till post-pregnancy to lose the extra baby weight–the reality star is already hitting the gym as seen here for an early morning workout in Studio City, California on Thursday.

Kim recently praised sister Kourtney Kardashian on her new slim figure, writing on her website: “How incredible does Kourt look!? She has lost 44 lbs in 6 months since giving birth to Penelope and looks better than ever. She is an inspiration to me!”

Kim added, “While we were in Miami we would always work out together and keep each other motivated and I am so proud of her!”
