Fitness enthusiasts and novices alike appreciate bike riding for its fun and fast exercise benefits. Regular cyclists gain both speed and strength because biking requires both muscular and cardiovascular endurance. In general, cycling utilizes primarily the lower body muscles, but the core and arm muscles are also used. The quadriceps, hamstrings, calf and gluteus muscles perform the bulk of the biker's work.
The most obvious area of muscle building during bike rides is the lower body, more specifically the legs. Cyclists build the two main muscles located in the calf: soleus and gastrocnemius. The soleus helps to lift the heel and the gastrocnemius is the prominent part of the calf that allows riders to go.
