Jelena Jankovic gives us a tip: Read her body language and determine how healthy she is.
"As long as I'm doing the splits, that means I'm healthy. When I'm not, you know there's something wrong. I'm not too sure about my body. If I go into a split, who knows if I'll come back up?"
JJ, I'm wishing you many more splits in your career, of course those from which you will be able to come back up!
