The link I gave for Jane Brody's New York Times article appears to be dead. Thanks for the heads-up, PastaQueen. I'm having trouble getting a direct link to work, as well. Grrrrr. Doncha just love this high-tech stuff sometimes?
Anyway. Go to http://www.nytimes.com. Click the "Health" button on the left side of the page. Look for the link to Jane Brody's "Personal Health" column. The title of the piece is "Exercise = Weight Loss, Except When It Doesn't." Here's a direct link to copy and paste if you need it:
I couldn't get it to work in Mozilla, Firefox G5 or Safari, though.
And to DietGirl: I used to row for an hour, when I was much younger and much fitter. I can do 20 to 30 minutes now, but doubt if I'll ever go back to those marathon rowing sessions.
