It is just a matter of having a system. I eat five times a day to regulate my metabolism. When I get up the morning I do a calisthenics routine and then go do a little run before I shave and shower. I work on the 16th floor. I never take the elevator. Every couple hours I walk down to the first and walk back up to my office. I generally do about 130-150 flights/day. My daughter and I usually go for a longer run in the evening.
