Hilary Duff might have a 1-year-old son at home, but the new mom still finds time to work out. And all that exercise is clearly paying off.

Duff stepped out in leggings and a tight tank top on Tuesday looking better than ever. X17 Online reports that the 25-year-old beauty was leaving a Pilates class when photogs snapped some shots of her in the body-clinging workout attire.

Since giving birth to her son one year ago, Duff has been working hard at dropping the baby weight. She stunned Ellen DeGeneres when she sat down with the talkshow host last week. "You look fantastic ... Were you here a year ago really? And you look like this?" asked DeGeneres.

The "Two and a Half Men" actress managed to lose 30 pounds in under 12 months.

"I feel elevated and better about myself when I do work out," Duff told Us Weekly in February. "My one trainer helped me lose a sh-t ton of weight. I lost like 30 pounds. His name is Gabe Johns and he is amazing. He's a boxing trainer and he comes to my house. I live in the canyon, so we just run. He runs my ass up and down the hill."

The former Disney star has been doing circuit training, boxing and Pilates to get her hot, new-mom bod.
