I am trying to lose some of my weight, but I’m terribly out of shape and get really tired exercising. I can’t do workout as all my body is paining due to exercising and may be this is not my type of thing to do. I know that walking can also help me and it is easy to do as well. I feel like I could do a lot of walking, though, and I want to know if it would help. How many calories can I burn in walking one mile?
