Super slim model shows off taut post-pregnancy tummy

The childbearing public was transfixed as model Sarah Stage sailed elegantly through her pregnancy, enduring neither swollen feet nor stretch mark. Now, having given birth to a healthy 8lb boy just last week, Stage posted this incredible post-pregnancy shot on Instagram, saying she is "excited to resume workouts in five weeks". The lingerie model (30) put on 28lb while pregnant with baby James Hunter, but is already rocking a six pack and a flat tummy despite only giving birth last Tuesday. Besides the occasional trip to the takeaway, Stage kept her diet healthy, sticking to quinoa, spinach and chicken throughout her pregnancy. We'll have whatever she's having, please.
