Well, I try to exercise about one and a half hours a day give or take 15 minutes. Even if people commute, you don't mean to say they can't even do half of that a day? Even a walk after dinner for a half an hour is beneficial.
I think the biggest problem people have with the adkins diet is there doesn't seem to be any mention of exercise, I could be wrong as I have never looked into his diet as I never really need to diet, I just do so about once a year to burn off the weight I accumulate during my normaly sedintary winter lifestyle.
That's a good point. In addition to the longer commute, an urban family generally has more "other stuff" going on simply because they can. The key for anyone is to sit down and write a list of no more than five things that are important to you. Focus on them (and make sure "exercise" is one of them), and disregard the rest.
My problem is this: Which of the five should I toss out the window in order to keep FreeRepublic on the list? LOL.
