Serena Williams shows off her Grand Slam winning body in this month's edition of Fitness Magazine. Williams appears on the May cover of the monthly, which features an interview with the 32-year-old World No. 1 inside.

Williams opens up about body issues in the interview, saying "When I was young I thought I should be built more like an athlete--long and lean--not with a womanly figure. But then people my age started coming up to me and saying, 'I love you because of the way you look.' That was really motivating. So I learned to be proud of my curves and embrace my large boobs. It's all about loving who you are and realizing that you're beautiful."
