Since we're discussing anecdotes, here's mine. I find aerobic exercise / running extremely boring. My ADD kicks in and my mind wanders like crazy. I find it hard to do because it's so boring. Anaerobic exercise / lifting weights is the opposite. I focus intensely on what I'm doing. I shut out the world. Time flies by. It's like intense meditation for me with the bonus of building muscle.
