Many experts still think that exercise treadmills are the best peice of exercise equipment you can get for workouts at home. They're pretty easy to use and widely available. And for most people, running is the best type of aerobic exercise. It strengthens the muscles of your legs, improves cardio-respiratory endurance and circulation, and burns calories. The treadmill is a great option if you can't or don't want to actually run outside. Whether it’s snowing, raining, when the ground is too muddy, or if it’s too hot, too windy or too cold, you can still keep to a schedule. The treadmill can also be recommended to exercisers of almost every age and both sexes.
