A stationary bike is a piece of exercise equipment designed for indoor cycling. It features a seat, handlebars, and pedals, allowing users to simulate riding a bicycle while remaining in one place. Stationary bikes come in various styles, including upright and recumbent, catering to different fitness levels and preferences. These bikes are popular for cardiovascular workouts, helping to improve heart health and burn calories. Many models include adjustable resistance settings and built-in displays to track metrics like speed, distance, and calories burned. Using a stationary bike can be an effective way to stay fit, especially during inclement weather.
