Hilary Duff has had her weight scrutinized over the last few years -- for a while there, she was scarily thin -- but she seems to have a healthy amount of muscle and some feminine curves now, and she gives some of the credit to Pilates.

The erstwhile Lizzie McGuire actress told People magazine, "I was a gymnast before, so I was a bit more bulky in the past. [Now] I have leaner, longer muscles, my strength is up."

Looks to me like she's found a great balance of healthy eating and exercise -- perhaps due in part to her relationship with a professional hockey player. At any rate, it's great to see her looking strong and healthy!
