Agnieszka Radwanska tells ESPN The Magazine that she likes to do 300 sit-ups in a single session and has unusual eating habits for a tennis player. Radwanska and American John Isner posed nude for the magazine’s “Body Issue.”

“Unlike most players, who eat at least two hours before matches, I can eat a full meal and go straight out on the court. In fact, I prefer to do that,” said Radwanska. “My usual routine is a plate of pasta 30 minutes before I’m due to go on court. If I don’t, I end up starving mid-match. That habit dates back to when my dad used to pick me up from school and drive me straight to matches. We had no time for dinner, so I had to stuff myself in the car.”
