Which Muscles Does Riding a Bike Develop?

Cycling is a fantastic sport that is enjoyed all over the world by millions of people each day. Lots of people ride a bike just as a means of transport, whilst others include cycling heavily in their fitness regime. The fitness benefits for your muscles varies quite a lot depending on which type of cycling you do. If you cycle very long distances at relatively low intensity, your muscles will become very good at endurance and will build many slow-twitch fibres. Conversely, if you ride at a high intensity over shorter periods, you will develop more fast twitch (powerful) fibres and build muscle size. But which muscles get worked the most when cycling.

Quadriceps (thighs). Without doubt the muscles that produce most of the force when cycling are the quadriceps. These muscles work to extend the knee joint and provide a downward force on the pedals, which is then passed onto the crank. Racing bikes in fact are designed to locate the quads directly over the crack so that maximum efficiency is achieved. When travelling at speed the quadriceps contract and relax at an incredible rate and a great deal is demanded of them.

Gastrocnemius (calf muscles). The muscles of the calf work just as hard as those of the thigh, and relative to their size they produce a lot of power.When the leg is straightened by the quadricep muscles, there is still a percentage of power that can be gained by flexing the calf muscles and pointing the toes downwards. Pinarello make pedals that dynamically pivot to squeeze every last bit of power juice from the calf muscles.

Hamstrings. After the quads have forced the leg down and helped move the bike forwards, the hamstrings work to to pull it back up again and reset the leg ready for another push. This doesn’t require much force on a standard bike as the rotation of the pedals pushes the leg up but when you use cycling shoes that clip to the pedals, a large amount of additional force can be generated by these muscles in the upward movement
