Treadmill

A treadmill is a device used for walking or running in place, featuring a moving belt that rotates around a frame. Most modern treadmills are motorized and powered by electricity, while some manual models rely on user-driven belt motion. The belt speed and incline are adjustable to simulate different terrains and intensities.

Motorized treadmills use a drive motor to propel the belt, with options for incline and cushioning. Manual treadmills have no motor; the belt speed is controlled by the user’s effort. Treadmills may include programmable workouts, heart rate monitoring, speed and incline presets, data displays, and some fold for home storage.

Common uses include cardiovascular training, endurance building, weight management, gait rehabilitation, and physical therapy. They are widely found in home gyms, fitness clubs, and clinical settings.

Safety considerations: use a safety key or tether, start slowly with warm-up, wear appropriate footwear, keep the area clear, and stop if dizziness or pain occurs. People with certain medical conditions should seek advice before use. Regular maintenance includes belt alignment, tension checks, cleaning, and occasional lubrication as recommended by the manufacturer.

History: Originating in the 19th century as a power-generating device in prisons, the treadmill evolved into rehabilitation equipment and, in the late 20th century, into popular fitness equipment for home and commercial use.
