Given gym costs, I'd find it a bit unfair that obese people would get such privilege for free (yes, I consider gym a privilege), when they could walk/jog in the park for free instead. For the really overweight, it's really the diet (and lots of discipline) that needs to change first.
Oh a side note, I think we are going to have a repeat of this thread: http://forums.hexus.net/general-disc...9-fatties.html
