Who to interview

I am going to be interviewing My old gymnastics coach. I've known her since I was about five or six and she's always been helpful. She's been coaching gymnastics for a long time so she has an amassed knowledge of competitions  and what it takes to get in shape. I think she'd be a good person to interview. In addition to asking her the standard questions, I plan on asking her about her background in Gymnastics. All I know is that she came from Germany, I don't know how she leaned or got into gymnastics. I also plan on asking her about the training and practice required to become a good gymnast.
