I already did a post about exercise motivation but I saw this commercial on TV the other day and it really got me thinking.
What I saw in it that made me think was how our motivation has changed from our ancestors. Thousands of years ago our ancestors main motivation in life was to eat, now some people don't eat by choice. In the past humans had to run and hunt for food but now we can go to the supermarket. So what keeps us motivated to stay fit? Media stereotypes? Occupational requirements? The book refers to "exercise high" as one of the motivational factors behind why we exercise. But I would imagine that the reason why most people exercise is because we feel "fat".
