Great article. There's an awful lot of it about, and a lot on these forums.
I think, however, that excerise compulsion is as bad as any other compulsion, so in this I disagree with Bobbi. To the extent that over-exercising leads to injuries, depressed states of mood, disatisfaction with one's self and disrupts relationships with others because the person views their exercise time as the most important part of the day, at the expense of husband and children or wife and children, then I think this is as bad if not worse than an oreo addiction.
I have a chocolate addiction and eat it every day. Nancy is addicted to ice-cream and eats a lot of it, with gusto ;-) . Neither of these "compulsions" is going to kill us. Neither isolates us from our families.
Exercise compulsion is another branch of mood disorders and should be taken seriously. If you never take time off from exercise, you have a problem.
Thanks for posting this Hotbikerchick: it's a timely reminder.
