Fit for a Cause: Real Women Who Are Changing the World

Cynthia Steger, 48, Williamsburg, Virginia

Raised $15,000 for the American Heart Association

Cynthia, whose oldest brother died of a massive heart attack at age 29, had her first heart attack four years ago, at age 44. This will be her third year doing the Start! Heart Walk in Newport News, Virginia. "The beautiful thing about a walk is that it's not just about giving money -- you're doing something to reduce your risk of heart disease, too," she says.
