I can attest to the tremendous increase in energy, as a participant in walking for exercise. I lost 74 lbs. In one year, by simply adding walking to my routine. I had been dieting for almost two months, with very little in the way of results. My physic suggested walking before I’ve never been so impressed. My energy levels were three times what they were before beginning the walking, and I truly enjoyed the peace of mind that I achieved during those daily walks.
