Turns out, being a pro tennis player helps keep Caroline Wozniacki in INSANE shape!!
Check out the 29-year-old showing off his shredded bod while rocking a bikini on an L.A. rooftop this week.
Wozniacki has been super busy this year -- when the former #1 ranked player in the world isn't playing tennis, she's been taking classes at Harvard Business School as part of a program that helps athletes build a second career outside of sports.
Caroline is enrolled in the course with her husband, ex-NBA star David Lee, figure skater Ashley Wagner, Knicks guard Reggie Bullock and more.
