A recumbent bike is a stationary exercise bike designed with a unique seating and riding position. Unlike traditional upright bikes, in which the cyclist sits on a narrow saddle, pedals and leans forward, recumbent bikes feature a reclined or semi-reclined seat back with the cyclist's legs stretched across their the front.A recumbent bike can support your back while also giving you a good cardio workout. It's also a popular choice because you can exercise while seated, so it's a very comfortable piece of equipment to use when you're doing it. You can use recumbent exercise bikes to relax when you're tired from working out in the gym. They're also ideal for recovery. The comfortable chair and backrest relax your upper body, allowing you to focus on lower body training
