Cycling is a low-impact aerobic exercise that targets several muscle groups in the lower body, including the quadriceps, glutes, hamstrings, and calves. The quadriceps, located in the front of the upper leg, are responsible for extending the leg at the knee and are the primary muscles used in cycling. The glutes, located in the buttocks, are the second most used muscles in cycling and are responsible for hip extension. The hamstrings, located at the back of the upper leg, are responsible for knee flexion and are used to bring the pedals back towards six o’clock. Cycling also engages the core muscles, including the abdominal and back muscles, which stabilize the upper body, especially when cycling out of the saddle. The muscles in the back, including the lats, traps, and rhomboids, help riders maintain proper posture and stability on the bike, while the arms and shoulders, including the biceps and triceps, are constantly engaged as riders work to control the bike. However, cycling is not a strength training exercise, and it is recommended to do weightlifting exercises, such as squats, leg presses, and lunges, to enhance cycling performance and make the legs even stronger.
