Question: Do you do any knee exercises?

Carl Lewis: No, because my knees are so bad. When I came to Houston as a freshman I couldn't take more than one jump a meet. After one jump I was limping, and I had to rest my knee. I have a lot of scar tissue between the muscle and tendons. I have tried chiropractors, doctors, even faith praying. Finally I worked myself up to being able to do more than one jump. But as a freshman, one jump was all I could do.
