I too find walking to be the most convenient form of exercise, and I love to walk. It is better than staying indoors and doing other forms of exercises. It does not have to be brisk walking either. I can cover more ground if I am walking at a moderate pace. When I am out walking, I get to look around at the scenery while at the same time breathing in some lovely fresh air, as I like to walk near the beach. It is also an opportunity to butt up on some friends who may also be out doing the same thing.
