Stationary exercise bikes put less strain on joints than other pieces of exercise equipment. Exercise bicycles are used to increase general fitness, to train for cycle events, and sometimes in physical therapy.
A semi-recumbent exercise bicycle takes a position between a conventional upright bicycle and a full recumbent bicycle. These semi-recumbent bikes excel in the areas of comfort and ease of use, but do not rank high in aerodynamics.
Many exercise bikes include attached televisions or other decides to provide entertainment to the user while he or she is riding. Many people enjoy using an mp3 player to listen to music while exercising.
