Which Muscles Does Cycling Work The Most?

Cycling is one of the most popular sports in the world and it is estimated that there is over 4 billion bikes world wide now. Lots of people ride a bike just as a means of transport, whilst others include cycling heavily in their fitness regime. Generally speaking the type of cycling you do will affect how your muscles will adapt. Cycling for long periods of time, but at reasonably low force, will encourage your muscles to build slow-twitch fibers and improve their endurance levels. Conversely, it is powerful fast-twitch fibres that are built when your riding style is of high intensity but over shorter periods of time. So which muscles get worked the hardest when you ride a bike.

Quadriceps (thighs). Without doubt the muscles that produce most of the force when cycling are the quadriceps. These are the muscles that straighten out the leg and produce the down force on the pedals, which in turn rotate the crack. Racing bikes in fact are designed to locate the quads directly over the crack so that maximum efficiency is achieved. When cycling fast, these muscles are contracted and relaxed hundreds of times a minute and so they need to be in good shape.

Gastrocnemius (calf muscles). Although the calf muscles are much smaller than the quadriceps, they still do and important job of transferring power to the pedals.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. Whist the quadriceps provide the downward power that propels the bike forwards, it is the hamstrings (back of the legs) that work to bring the leg back up into a flexed (bent) position. 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
