Walking in the evenings

We have decided that we would walk if possible after dinner each night. We both want to lose some weight and get exercise. We have been with it a week today so far. I have more energy and feel overall better. Have yet to see a change in weight but it will come. We walk about 3-4 miles each night. The girls really enjoy it walking around and enjoying the weather. I could probably walk more most nights but because of the girls we only do the 3-4 miles.
