Running machines, commonly known as treadmills, are exercise devices that allow people to walk, jog, or run indoors. They have a moving belt that simulates outdoor running, making it easy to maintain a fitness routine regardless of the weather. Many treadmills come with features like adjustable speed and incline, helping users customize their workouts to match their fitness levels. Using a treadmill can be beneficial for cardiovascular health, weight loss, and overall fitness. They often include built-in programs that guide users through different workout intensities. With the convenience of being at home or in a gym, treadmills make it easier for anyone to stay active and healthy.
