cat running up a slideThe treadmill. The elliptical. The Stair Master. Such are the machines that line the gymnasium floor, each providing supremely effective cardiovascular exercises that consist of its user running, climbing, or walking to nowhere (for at least twenty minutes, all you gym rats!).
