Young Blonde Girl Reveals Her White Top And Short Jeans On The Stationary Exercise Bicycle

Uses
Exercise bikes are used for exercise, to increase general fitness, for weight loss, and for training for cycle events. The exercise bike has long been used for physical therapy because of the low-impact, safe, and effective cardiovascular exercise it provides. The low-impact movement involved in operating an exercise bike does not put much stress on joints and does not involve sporadic motions that some other fitness equipment may require. However, as with typical biking, extended use of a stationary bike has been linked to decreased sexual function.
Stationary bikes are also used for physical testing, i.e. as ergometers for measuring power. Traditionally this is done by imposing a certain level of resistance mechanically and/or measuring this. gives a good overview. Modern ergometers and even many consumer exercise bikes are fitted with electronic sensors and displays.
Ergometers, such as CEVIS (Cycle Ergometer with Vibration Isolation and Stabilization System), are used in space (e.g. in the ISS) to counter cardiovascular deconditioning in the microgravity environment.
