The main benefit of using a treadmill is that it allows you to exercise indoors and stay motivated. You can set goals for yourself, such as running a certain distance or time, and track your progress. Treadmills are also safer than outdoor activities because they provide a controlled environment with proper safety features like handrails and shock absorption technology. Additionally, some treadmills offer programs that help improve your fitness level, such as interval training and heart rate monitoring.
