Hi Stef
I wonder if you can help me. I have just come back from a very brisk hour and a quarter walk (with a dog who is on his knees begging for mercy) and I thought I would see how many calories I burned. So I went to FitDay.com and put in what I had done, guessing at 4mph and it said I had burned 254 cals. Then I thought, I wonder what a 2 and a half hour walk at 2mph burns up - it said 254 cals - again! No matter what way round I did it, if I did a 5 mile walk at any speed it burned 254 cals.
So why do doctors, articles, etc, etc, tell us to walk briskly for a minimum of 20 mins when we could be ambling happily along for 40 mins burning the same amount of calories?? Is there some other factor involved that makes it better for us?
