Lindsey Vonn busts her ass in the gym ... so why not show it off on the beach?!
The Olympic skiing legend posed for a series of bikini pics taken during a recent vacation with some friends ... and she looks incredible.
"You can judge me if you want, but I’ve been working hard in the gym and taking care of me," Vonn said ... "So I’m going to post some bikini pics because I’m proud of myself."
36-year-old Vonn is still a gym-aholic, despite retiring from competitive skiing in 2019.
