Most people who roll up to the gym couldn't care less about what they look like, because they're about to pump their own sweat into everything they're wearing!
Hilary Duff on the other hand makes it look like she cares and makes it look EASY when she goes to the gym!
In the stylish green top with and adorbz scarf, we have no doubt she turners head all the way up to stepping on her favorite treadmill!
The mom of one (Luca, who's getting closer and closer to 2 every day!) has been working on her fitness for quite some time, and it totes shows!
Keep up the fab werk, girl!
P.S. — We wonder what Luca's gonna be for Halloween! We hope none of THESE wildly inappropriate kids' costumes!
