Want Toned Legs? Get on Your Bike
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 (thigh muscles). The muscles that are worked the hardest whilst cycling and so need to be the most developed are the quads. 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. The quad muscles thankfully adapt quite quickly to exercise, which is lucky as bike riding forces them to work at quite a rapid rate.
Gastrocnemius (calf). Although the calf muscles are much smaller than the quadriceps, they still do and important job of transferring power to the pedals. Flexing the calf muscles when the leg is in a straight position, points the toes towards and adds a small boost to the overall power output. Pinarello make pedals that dynamically pivot to squeeze every last bit of power juice from the calf muscles.
Hamstrings. It may be the thigh muscles that provide most of the forward momentum when riding, but in order to flex the legs and prime them for the next downward push, it is the hamstrings that do the work. 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
