Overview
Bicycling is thought of primarily as a form of cardiovascular exercise. However, it can also help strengthen and tone several muscle groups. Bicycling not only works your heart and lungs but also several parts of the upper and lower body. Hop on a bicycle a few times a week to enjoy an effective, low-impact workout.
Upper Legs
The upper legs are the primary part of the body worked while bicycling. The quadriceps, a group of four muscles on the front of the thigh, are of particular importance. These muscles act as powerful knee extensors and are activated with each downward push of the pedal. The gluteus maximus, located on the posterior hip, is another important bicycling muscle. This muscle is engaged when pushing the pedal through the lowest position. A group of muscles on the back of the thigh known as the hamstrings are also used while bicycling to bend the knees.
Lower Leg
Bicycling has the potential to really work the calf muscles of the lower leg. This is determined by where your foot is positioned on the pedal. If the front part of your foot is on pedal, then you will work your calves significantly more than if the back part of your foot is on the pedal. The average person pedals with the middle of the foot, which will give your calves a moderate workout.
Shoulders and Arms
While your lower body is putting in most of the effort required to power your bike, your shoulders and arms are still a necessity. These body parts are used not only to steer and brake the bike but also to support your upper body, especially if you're using a racing bike.
Core
Although not worked to the point of fatigue, the muscles of your core are used while bicycling. Your core includes the muscles of your back and abdomen, all of which are necessary to stabilize your torso in the upright position. Whether you're hunched over on a racing bike or sitting tall while taking a Sunday ride on your single-speed bike, this part of the body will be worked.
