I exercise every morning. I do light weights - 5lb and 10lb arm exercises - and then lie and lift my arms and legs. It's all about keeping core strength. I do a lot of stretching too.

I don't lift weights. I do fitness exercises to stay strong.

I exercise at least five times a week with stretching, Pilates, push-ups, planks, sit- ups, squats and light weights.

I do heavy weights in the morning for about an hour, and then I do 45 minutes of higher-volume lifting in the afternoon. My least favorite is the legs... I do quite a few chin-ups and rows. I do mostly old-school lifting with a lot of squats.

Well yes so far, I was recently in Germany and they had me do six book signings a day and that was too much so I had them cut it down to about three. It becomes taxing at times but its a lot of fun and you meet a lot of nice people.

Don't you find that the more you know, the more you don't know and can't ever learn because there's too much stuff out there?
