I'm going to second almost all of you (I don't know the political affiliation of my gym owner) and say that a lot of the factors already brought up motivates me. I like looking good and all the things that come with looking good and being in shape. I like feeling good and all the good things that come from that too.
I also look at the investment portion. I have lots of expensive slim fitting clothing, and I would rather not have to replace them. Also, if I were to think about all the money I'd spent on gym membership fees, lessons, training, gym apparel, supplements, etc ... oui!
Considering how much time I've spent on playing sports and staying fit through my entire life; and the resulting opportunity costs keep me in the game too. Why slack now? Why slack ever?
... and when all else fails and I'm drowning in work, I remember they're open late, people who have to work out late and I have stimulants.
