Hilary Duff just gave birth to her son Luca last month, and is finding it hard to get back into shape.  She tweeted over the weekend:

’20 minutes on the elliptical seems like an eternity!!! What the hell…’

Ugh, I hate that feeling – when you haven’t been to the gym in a while and then that first workout is soooo hard!  But I’m sure that Hil will bounce back fast.
