A treadmill is a popular fitness machine designed for indoor walking, jogging, or running. It features a moving belt powered by a motor, allowing users to exercise regardless of weather conditions. Most treadmills offer adjustable speed and incline settings to customize workouts. They often include digital displays to track time, distance, speed, and calories burned. Advanced models may have heart rate monitors, preset programs, and Bluetooth connectivity. Treadmills support cardiovascular health, aid in weight loss, and improve overall endurance. They are convenient for home workouts and suitable for all fitness levels. Safety features like emergency stop buttons add protection during use. Compact or foldable designs make them ideal for limited spaces.
