When exercising on an electric treadmill, certain benefits are no-brainers: you get selectable speeds, adjustable inclines, and protection from Mother Nature’s harsher conditions. However, electric treadmills offer a few hidden advantages most people don’t consider, adding to their appeal as exercise machines. For instance, consider your running shoes. When you’re serious about pumping out mileage, your soles get plenty of wear and tear — especially if you run outdoors over rugged terrain, rocks, gravel, or rough pavement. When you run on an electric treadmill instead, you incur far less footwear damage — which saves you the cost of buying pair after pair of expensive running shoes. And as the Electric Treadmill Review site explains, treadmills are extreme time savers. It may seem like running outdoors is efficient, but if you ever need to cross streets with stoplights, trek several blocks to a running trail, or find a new route when your usual one is too muddy or icy, the efficiency of an electric treadmill becomes glaringly obvious.
