Harvard Health supports bicycling as an effective form of exercise that provides several different benefits for the body, especially muscles and bones. Cycling uses the glutes, calves, and thighs and builds these muscles. It also requires use of the abdominal muscles to remain upright while moving, and strong abdominal muscles help the legs and core look more defined.
Because bicycling involves pedaling, it builds bones. The constant pedaling motion works and pulls the muscles, and the muscles pull the bones, increasing bone density and making the bones less likely to break. Finally, cycling is ideal for individuals with joint problems, as sitting and pedaling takes the stress of exercise off the legs.
