Pilates has been GOOD to Hilary Duff!

We mean, there she is just heading into the gym for her pilates class, not really wearing anything special (including make up), and we’re stunned by how great she looks! Those curves are right and she looks super happy and healthy!

Plus, she totally knows to hydrate, and a smart person is a sexy person!

Get on her level! Time to hit the gym, no excuses!
