I don't believe in purgatory, but if there is one, I should be exempt: the treadmills at my gym face the pool, and all I see when I look out is the cast of Cocoon doing water aerobics. I survive with some Zeppelin in my headphones, perhaps the promise of a Miller Lite at week's end, and in my case watching the guys pump iron just a few feet away. Having other people around is a definite motivation factor.
