Cycling classes focus on endurance, strength, interval, and high intensity training using the stationary bike. It is mainly an aerobic activity, which means that your heart, blood vessels and lungs all get a workout. You will breathe deeper, perspire and experience increased body temperature, which will improve your overall fitness level. A recent study found that elderly patients with knee pain and osteoarthritis actually improved their condition when cycling was introduced to their routines. It shouldn¡¯t really come as a surprise that weight loss is one of the big benefits of regular cycling.
