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 major muscles in the arms include the deltoids, biceps and triceps. The deltoids are the major muscles in the shoulders and are responsible for lifting the arms up forward and out to the sides. The biceps brachii runs down the front of the upper arm and is in charge of bending the elbow joints against resistance.
