Hilary Duff scarf pilates spandex baby weight sunglasses The Duffster is still working on getting buff!

Hilary Duff hit up yet another Pilates class in Studio City yesterday, and the Lizzie Maguire star is clearly taking her post-baby slim down seriously! Clad in black spandex, a white t-shirt, and a leopard print scarf, the new mom already looks like she's lost most of the pregnancy pounds. You go girl!

Not that the 24-year-old enjoys the strict regime it takes to get your body back in tip top shape!

"Ordering salad dressing on the side depresses me. I know it's the right thing to do but honestly... Isn't it just depressing?!" she tweeted yesterday after her workout.

We feel you Hil! The pay off is worth it though!
