Lindsey Vonn
 

Olympic ski champ Lindsey Vonn posted an Instagram photo of herself on the slopes Wednesday in Chile along with a caption that explained one of her fitness philosophies:

This is why I never miss leg day=so i can ski 85mph down an icy mountain and always be confident in myself because I know I put in the work.


If you're wondering why Vonn felt compelled to discuss her feelings about leg day, consider that two days earlier she posted a video showing herself putting in some work:


When Vonn sustained a serious knee injury in March, she used Instagram to show a creative way of maintaining her killer abs.
