Does cycling make your legs slimmer or fatter?

In the modern society that pursues health and sports, cycling, as a green and environmentally friendly way of travel and an efficient form of aerobic exercise, is favoured by more and more people. However, many girls who want to join cycling doubt that is whether cycling will make their legs fatter. In this article, let’s find the answer.

Cycling leg

First, let’s be clear that cycling does not directly cause fatter legs. Whether the legs become fatter or not is affected by many factors such as genetics, exercise habits, diet, and nutrition. Cycling as an aerobic exercise, it is main function is to enhance cardiopulmonary function and improve the body’s endurance, rather than specifically targeting leg muscles for muscle-building training. 

1. However, why do some riders feel that their legs become fatter after cycling? There are several factors.
(1) High cycling intensity or cycling for too long

Cycling for long periods or at high intensity can lead to overuse of leg muscles, causing muscle fatigue and micro-injury. This micro-injury may prompt the repair and growth of muscle fibers during the recovery process, increasing leg muscle size. But this does not mean that the legs will become noticeably fatter, as muscle growth is usually modest and regulated by a variety of factors. 

(2) Incorrect riding posture 

Riding posture has an important impact on leg muscle stress. If the riding posture is incorrect, such as sitting too high or sitting too far forward, it may cause the calf muscles to be overly involved in exerting force, thereby increasing their burden. Riding with incorrect posture for a long time may cause the calf muscles to be overdeveloped, giving the illusion that the legs become fatter. 

(3) Poor venous return of the lower limbs

Cycling for a long time may cause the venous blood return of the lower limbs to be blocked, especially when the riding posture is incorrect and the riding time is too long. It can cause varicose veins in the lower extremities, making the legs appear more swollen and bulkier.

(4) Individual Differences

Everyone’s body reactions and physiological characteristics are different. Some people may be naturally muscular and easier to gain muscle mass even while doing aerobic exercise such as cycling. In addition, depending on personal genetics and physical differences, some people may burn fat in the upper body first when doing aerobic exercise, while fat in the lower body is difficult to reduce, which may also cause the legs to look fatter. 

2. How can cycling help us slim down our legs?

(1) Adjust your riding position

Keep your body straight and avoid leaning forward or backward too much. This will help reduce the pressure on your waist and back and allow your leg muscles to better participate in the movement. At the same time, pay attention to the position of your feet and ensure that the soles of your feet are fully attached to the pedals to avoid uneven stress on your toes or heels. For specific adjustment methods, please refer to our previous articles ( ) ( ).

(2) Control the intensity and duration of cycling

Appropriate cycling intensity can stimulate the growth of leg muscles, while long-term cycling can help burn leg fat. Generally, each riding time should be more than 30 minutes, and the heart rate should be controlled between 60% and 75% of the maximum heart rate. This can achieve the exercise target without causing muscle damage due to excessive intensity.

(3) Stretch and relax after cycling

After a ride, proper stretching can help muscles recover, reduce lactic acid accumulation, and prevent muscle stiffness and pain. You can choose stretching actions for the thighs’ front, back, and calves. Hold each action for 15 to 30 seconds and repeat 2 to 3 times.

(4) A reasonable diet

Cycling consumes a lot of energy, so make sure you consume enough protein, carbohydrates, and fats to maintain normal metabolism and repair your body. At the same time, pay attention to controlling total calorie intake to avoid excess calories leading to fat accumulation.

In conclusion, by adjusting the riding posture, controlling the intensity and time of riding, stretching and relaxing after riding, and having a reasonable diet, we can effectively achieve the target of thinning our legs through riding. However, it should be noted that everyone’s physical condition and exercise needs are different, so in actual operation, you should develop a suitable cycling plan based on your status.
