1. Expand the contact area between the buttocks and the seat cushion, disperse the pressure, and reduce the local pressure on the buttocks. 2. The thick filler can absorb more shock and vibration from the frame. In fact, a wide and thick seat cushion does not necessarily reduce butt pain. Let's first look at the cause of butt pain: 1. Compression: When sitting on the cushion, the weight of the body presses on the small area of the cushion, which will generate a very large pressure, which will compress the capillaries and affect the blood circulation. 2. Shearing force and friction: When pedaling, the human body will sway slightly on the cushion, rubbing the edge of the cushion, causing friction, friction, and heat, which will soon cause pain and skin damage. The shear force generated by friction with the cushion combined with the compression effect further aggravates the blood circulation disorder. 3. Moisture: The moisture brought by sweat has aggravated the effect of shearing force. 4. Temperature: When cycling, the skin temperature, especially the temperature of the perineum will rise significantly. The rise in temperature speeds up the metabolism of the skin, and under the action of compression and shearing force, blood circulation is obstructed. At this time, the skin begins to die because it cannot get sufficient nutrients. Obviously, the generous and thick saddle has an advantage in oppression. But the wide and thick seat cushion will bring more friction and shear force. The large and thick seat cushion is not easy to wick away sweat and is more humid. The large and thick saddle will make the butt temperature higher. Of course, compression is the main cause of butt pain. Generosity will bring comfort, but because of the last three disadvantages, we also know that large and thick seat cushions do not always make us feel comfortable. The benefits of the first item can be felt by sitting on it, but as the riding time is longer, the adverse effects of the latter three items are greater. This is why some seat cushions are very comfortable to sit on, but long riding time will make us very painful. We all know that sitting on a sofa is not the thicker the filling layer, the softer it is. The comfortable high-end sofa, the hardness, and filling thickness are all carefully designed, too soft sofas are often relatively low-priced products, Sitting for a long time makes it uncomfortable. The same is true for the seat cushion. The seat cushion is very comfortable and soft after sitting on it, which may make you painful after riding for a period of time. The filling foam of the seat cushion has good or bad materials, and the same material has different densities. A good cushion will be considered as a good filling material, with a moderate density, or even layered filling. The upper layer has a lower density and the lower layer uses high-density materials so that it will have a more comfortable touch without being too dented. At the same time, after we sit on the saddle, the seat bone position sinks, and the edge part is easy to bulge and press other places. The shape of the saddle is also very important. Therefore, we must be selective in choosing a large and thick saddle, look at its design and workmanship, consult cyclists who have used it, and do not pursue magnanimity.

The fairy tale kingdom Denmark not only has more than 7,000 kilometers of beautiful coastline, dense forests, and open grasslands but also has 11,000 kilometers of bicycle lanes. In Denmark, the right of way for bicycles exceeds that of cars. In places with narrow roads, cars cannot be urged by honking because the bicycle is slow. Here, the bicycle is not only a means of transportation but also a sport that people love very much. As the epidemic hits, bicycles are more popular as a means of transportation and sports because they can maintain social distance. 60% of Copenhageners commute by bike According to statistics, in Copenhagen, more than 60% of citizens’ daily commute is done by bicycle. Bicycle tours are a major feature of Copenhagen. The reporter who led the reporter on a cycling tour was an 82-year-old Danish grandmother who was very agile in getting on and off the bike and cycling fast. She said that her health is mainly attributable to her insistence on cycling around the streets and alleys every day. She is also very proud to tell me that her “riding age” has been 79 years, and her goal is to “cycling age” for 100 years. Denmark not only has common two-wheeled bicycles but also various tricycles and four-wheeled vehicles, some with a body in the front and some with a body in the back. A reporter from the “Global Times” once talked with a father who rides a front bucket bike. He told me that when a child sits on a front bucket, parents can always understand their children’s needs and children can also see a wider view. He believes that a bicycle can take the whole family to travel together, which is more environmentally friendly and closer to nature than a car. He also particularly emphasized: “I think that driving the bicycle with the child with his own power can directly express the close love between parents and children, and it is more natural and delicate than the power from the engine.” The reporter also visited. In a bicycle design studio in Denmark, the staff here use their brains to design many bicycles with various uses. They will also make decorations for bicycles according to world trends, making bicycles a platform for individuality and aesthetics. Priority to bicycle road rights Of the 20 global bike-friendly cities selected in 2019, more than half are from Europe, including Denmark. The right of way for bicycles in Europe is a priority, that is to say, on the road, cars must give way to pedestrians and bicycles. When the road is very narrow, it is very difficult to whistle the cyclist in front or forcibly overtake the cyclist. Acts of courtesy, and will face a large number of fines. Here bicycles, like cars, can be insured. If the bicycle is lost or damaged, or the rider suffers any personal injury during the ride, he can apply for compensation from the insurance company. This is a guarantee to encourage the public to ride. Many people take the train to and from get off work every day and use bicycles to solve commuting problems from home to train station and from the train station to work. Not only folding bicycles but ordinary bicycles are also allowed to push the carriage. In 2020, Brussels has designated many bicycle lanes, and cars and pedestrians are not allowed to enter. The city government believes that bicycles are the perfect means of transportation during the epidemic. There is no need to worry about the risk of spreading the virus caused by the dense crowds of buses and subways, and it is faster and more efficient than walking. From January 1, 2021, Brussels, the capital of Belgium, will become a city with a 30-kilometer speed limit. Except for special vehicles such as fire trucks, police cars, and ambulances, all motor vehicles including buses must comply with the 30-kilometer limit. Speed limit. The Brussels City Government believes that the right to use roads is not exclusive to cars, and the needs of bicycles and pedestrians must also be taken care of. Therefore, with the support of a lot of scientific data, the 30-kilometer speed limit policy has been released, and bicycle enthusiasts can ride more safely and comfortably.
In recent years, many young talents have died of cancer. Cancer has become the number one killer that seriously threatens the health of people all over the world. Many people are chanting campaigns to prevent cancer, but is there really an inevitable connection? Can exercise really prevent cancer? So,can cancer be prevented? Researchers from the American Cancer Center published a research paper in the Journal of the American Medical Association: Internal Medicine, saying that through data analysis of 1.44 million people in the United States and Europe, they found that the incidence of at least 13 cancers in people who exercise for a long time is significantly lower! So far, this is the largest and most comprehensive study of articles on exercise and cancer incidence. The paper in the Journal of the American Medical Association integrates many previous research data, surveyed the daily exercise volume of 1.44 million people in Europe and the United States, and then compared the two groups of 10% who exercise the most and the 10% who exercise the least. The entire exercise research data statistics span from 1987 to 2004, spanning 18 years, and the cancer incidence data tracking time is longer. How can sports prevent cancer? What is the principle of exercise to prevent cancer? In recent years, sports medicine research, tumor experimental research, and tumor cause investigation have gradually revealed the mystery and clarified many new mechanisms. 1. Improve the body's immune function and help prevent cancer Studies have found that cancer cells can only grow and reproduce when they escape human immune surveillance; if a person's immune mechanism is intact, no cancer will occur; if cancer patients can maintain and improve their own immune function, they can effectively Suppress and defeat cancer. Studies have confirmed that regular exercise can effectively improve autoimmune function. For example, exercise can significantly increase the body’s immune cells such as T lymphocytes, B lymphocytes, and phagocytes, thereby enhancing the body's ability to prevent cancer. Exercise can also increase the level of interferon in the blood, and interferon is also the body’s immune enhancer, which has anti-cancer and anti-cancer effects. 2. Breathing in more oxygen is beneficial to inhibit cancer Exercise can make people inhale several to several tens of times more oxygen than usual. The human body's oxygen intake increases and the breathing rate increases. Through the frequent exchange of gas in the body, more carcinogenic toxins can be discharged and the incidence of cancer can be reduced. At the same time, cancer cells are anaerobic cells that require insufficient oxygen for survival and growth. The environment; the internal environment with sufficient oxygen is not suitable for the growth of cancer cells, so it is more conducive to inhibiting cancers latent in the body. According to the research of German sports medicine professor Van Aken: "A person gets more than 8 times more oxygen per day than usual, which can prevent cancer, and even if they have cancer, they can prolong their life." Mexican oncologists tested 100 cancer patients. Three years of experimental observations found that with 2 hours of oxygen therapy a day, the survival rate of cancer patients can rise from 32% to 88%. 3. Prevent cancer cells from "settlement" and "metastasis" Human blood circulation speeds up during exercise. At this time, cancer cells are like small sand in the turbulent flow. They are not easy to "stand on their heels". Therefore, it is not suitable for cancer cells to "settle" to form spreading and metastasis; they are often affected by immune function during blood flow. The strong immune cells are eliminated. 4. Exercise can cause more sweating and discharge more carcinogens Every time you exercise, you will sweat much more than usual. Excessive sweating can excrete carcinogenic poisons such as nitrite, acetone, chloroform, sulfur, phenol, strontium, lead, mercury, and beryllium that are accumulated in the body to prevent cancer. 5. Improve the activity of antioxidant enzymes and effectively remove free radicals The human body produces a large number of free radicals in its metabolism. The accumulation of excessive free radicals in the body can damage cell membranes, proteins, nucleic acids and induce more than 200 diseases. It can also cause cell mutations and develop cancer. However, the human body also has a system for removing these free radicals. The function of scavenging free radicals is called "anti-oxidation". For example, superoxide dismutase and glutathione peroxidase in the human body are antioxidant enzymes that can effectively scavenge free radicals. The higher the activity of antioxidant enzymes in the human body, the stronger the function of scavenging free radicals, which can prevent many diseases and even cancer. 6. Exercise regularly to control blood sugar levels and "starve" cancer cells Nobel Prize winner Dr. Otto Warburg discovered for the first time that cancer cells and healthy cells are fundamentally different in terms of energy metabolism. Cancer cells ferment glucose in an anaerobic environment. Its absorption of glucose is 3 to 5 times that of healthy cells. It directly uses blood sugar as nutrition and almost only eats sugar. Regular exercise can promote metabolism, control blood sugar, maintain a good blood sugar level, and can selectively “starve” cancer cells present in the body, which is beneficial to cancer prevention and anti-cancer. 7. Prevent fat and lose weight, reduce the risk of multiple cancers Studies have shown that obesity is closely related to the occurrence of certain cancers. Obesity in men can increase the incidence of colorectal cancer and prostate cancer; obesity in women can significantly increase the incidence of uterine cancer, cervical cancer, ovarian cancer, breast cancer, and gallbladder cancer. And regular exercise can prevent obesity and have a weight loss effect. People with normal weight should consume all the calories they take in through exercise every day to achieve a "balance of income and expenditure" to prevent gaining weight; while for obese people, the calories consumed every day should exceed the calorie intake, which is beneficial. lose weight. 8. Exercise promotes bowel movement, avoids constipation, and helps prevent cancer The stool of the intestinal cavity contains a variety of carcinogens and carcinogens. For people with frequent constipation, the carcinogens and carcinogens in the stool can stimulate the intestinal mucosa in a large area, high concentration, and for a long time and easily induce a variety of cancers. Exercise can promote bowel movements, accelerate bowel movements, reduce the concentration of toxins in the stool, reduce the area of contact with the intestinal wall, reduce the time to stimulate the intestinal mucosa, and greatly reduce the risk of cancer. 9. Female friends who insist on exercising are particularly effective in preventing women's cancer Medical experts conducted a 21-year investigation and research on 8,000 Japanese in Hawaii and confirmed the effect of exercise on cancer prevention. In particular, women benefit more from exercise. Research results show that exercise can regulate female endocrine hormones (such as estrogen, prolactin), thereby reducing hormone-dependent breast, ovarian, uterine, and other gynecological cancers by 50%. American cancer expert Jerome Bullock pointed out that the most reliable way to prevent gynecological cancer is to insist on aerobic exercise for 3 hours a week. Exercise can prevent a variety of cancers related to endocrine hormones. 10. Exercise can invigorate people and improve their ability to prevent cancer A well-known American oncologist pointed out: “Cancer is the failure of immune function, and the failure of immune function occurs after the mental balance is disrupted.” Clinical diagnosis and treatment have observed that about 3/5 of cancer patients are due to trauma and emotional depression. And suffering from cancer or causing cancer to develop. Persistent exercise can regulate the secretion of human hormones, promote blood circulation in the brain, invigorate people, and cultivate sentiment. Exercise can make the human body secrete the brain chemical substance called “the river of happiness of consciousness”-cephalin. The chemical substance can regulate the function of the nervous system, improve mental stress, exercise will, make people feel happy, help eliminate worries and worries and improve the ability to prevent cancer. Which cancer risks can be reduced? Regarding the cancer risks that exercise can reduce, this article studied 26 types of cancer and found that exercise significantly reduced the incidence of cancer. The percentage of reduction in the incidence of 13 types of cancer is shown in the figure. Of the top 10 cancers in China, 8 of them can reduce the risk through exercise. Esophageal adenocarcinoma was reduced by 42%! Liver cancer 27%! Lung cancer 26%! The cancers with the highest mortality rates for men and women in my country are lung and bronchial cancer, gastric cancer, liver cancer, esophageal cancer, colorectal cancer, accounting for three-quarters of all cancer deaths.In order to make the conclusion rigorous, the researchers analyzed the surveyed subjects’ race, geographic location, education level, age, body weight, smoking, drinking status, hormone therapy, and other conditions and found that the above conclusions are not affected. How long is the best exercise? Understand the principle that exercise can prevent cancer, so what exercises can prevent cancer, and how long is the appropriate exercise time? Experts from the American Sports Association believe that aerobic exercises such as jogging, cycling, and swimming are most suitable. The ideal exercise rhythm is three times a week for at least 30 minutes each time, or four times a week for at least 20 minutes each time. As long as you go to the gym and walk or jog easily, you can easily achieve this rhythm. It is important to persevere. In fact, in summary, exercise does not really prevent cancer from occurring. It can only help you exercise your body, regulate immunity, and reduce the chance of cancer, but excessive exercise will also reduce your body’s immunity! In addition, there are air, water sources, mentality, etc. that affect your health.Exercise is not omnipotent, but no exercise is absolutely impossible!
Braking is simple, just press the lever, but is it really that simple? Of course not, let's take a look at the correct way to break! The front brake is important Many novice friends don't like or are afraid to use the front brake. In fact, the front brake is still very useful. Especially in the case of emergency braking, the front brake is more efficient than the rear brake. But you need to pay attention to two issues. The focus should be shifted back if you don’t want to fly out. Also, the brakes are now very easy to lock, so be sure to pay attention when using the front brake. This can be felt slowly while riding. If it is downhill, you can't just use the front brake, you need front and rear cooperation.It is not recommended to use the front brake when cornering. It is easy to slip. When using the front brake, the wheels must be straight. The rear brake is not that safe Many friends think that it is safe to use the rear brake. In fact, the rear brake is also very dangerous, especially in the case of high-speed riding. If the rear brake force is too strong, the rear wheel will lock and the rear wheel will slide. Sand or slippery, the consequences are disastrous. Friends who often ride bicycles must feel this deeply. Of course, the role of the rear brake is still great, mainly depending on the road conditions and your riding situation. When riding slowly, in bad road conditions, such as slippery roads or when the front brake of the front wheel fails. The rear brake works very well. Do not brake to the end, it is better to brake if it is a particularly critical situation.There is no fixed requirement for left front right rear or left rear right front. It depends on personal habits to adjust. Is disc brake or v brake better? This is a problem that many novice friends struggle with. In fact, the two cannot be compared at all. Different types of things have their own advantages and disadvantages. The biggest advantage of the v-brake at present is that the structure is very simple and convenient for maintenance.Therefore,the v-brake is generally chosen for long-distance riding. Disc brakes can adapt to a variety of environments, and the rain will not affect the braking efficiency.

1.Too tight Bicycles have become lighter and lighter, and the fault-tolerant rate of installation is getting lower and lower. Excessive torque will cause slippage of the chainring, twisting of the handlebars, and serious breakage during cycling. For many novices, some torque values seem very low, especially most of the control components. But in fact, these parts don’t need so much torque! The brake lever is a good example. The torque required to install the brake lever is usually only 4 Nm, which looks a bit weak, but it is enough to prevent the brake lever from turning up and down. Moreover, the lower torque can ensure that in the event of uncontrollable events such as crashes, rotation, and absorption of energy occur to avoid damage to accessories. Although you need to readjust after this, it is better than seeing a broken brake. Don’t forget to use a torque wrench, trust the recommended torque value when installing any components! 2. Spend too much/too little on accessories Of course, we can’t tell you how to spend your money, so if you have a large budget, just spend it. However, for those who have to plan carefully, some upgrades will appear to be much more. Those fancy/expensive carbon fiber handlebars may not enhance your riding experience. However, relatively inexpensive components like tires can have a big impact on your handling and average speed. 3. Do not bring spares, tools, etc. Your mountain bike can take you to some amazing places, which means that it is necessary to bring spare supplies and portable tools, at least to ensure that you can come back from deep in the mountains. Such as inner tubes, tire sticks, portable tools, and pumps are undoubtedly essential items! But if you plan to go further, or the riding environment is worse, then we have some suggestions worthy of reference. Such as a pair of brake pads, a pair of magic buckles. 4. Tire pressure is too high Too high air pressure is a mistake that almost everyone has made, especially those stubborn novices. Although too high air pressure will not cause snake bites, it will greatly reduce tire grip and reduce comfort. These two points should be avoided! We recommend starting from around 30psi and increasing or decreasing the tire pressure a little. Generally speaking, you will choose a slightly lower tire pressure to get the best grip and comfort, while excessive reduction may lead to snake bites. I know some truths are unclear, if you don’t believe it, please try and make mistakes yourself! Certain experiences should really make you try. 5. Like spray lubricants such as WD-40 If you want to clean disc brakes, choose a special cleaner like Muc Off. If you have to use a lubricant like WD40, don’t lose the slender plastic tube, it can lubricate the parts you need more accurately.
1. Cyclists are the strongest people. When cycling on the road, they don’t know when they will fall, but they are always ready to get up after falling. 2. Cyclists are the ones who enjoy life the most. They usually ride their beloved bicycles to the West Lake to enjoy the wind of East Lake, as if there is nothing more important than living in the world. 3. Cyclists are the most energetic and passionate people. They can pick up a map and ride their beloved bicycle just because of a simple dream as if there is no place in the world they can’t reach. 4. Cyclists are the most motivated people. They will never be satisfied with the configuration of their own bicycles at home and start to save money and buy new equipment for themselves. 5. Cyclists are the most romantic people. At their wedding ceremony, there are no luxury cars, only two long rows of bicycles swagger through the street, but they give you happiness that no one can compare. 6. The cyclist is the one who loves home most. After your child is born, he will teach your child to ride a bicycle. On weekends, he will take the three of you, mother and son, on a bike ride out for a picnic. 7. Cyclists are the most politically promising. There is a cowboy in the United States. He used to ride a horse and had nothing to do. Later, he switched to riding a bicycle and became the president of the United States. 8. Cyclists are the people with the most sense of humor. You can see the person who wrote this post. 9. Cyclists are the people who are most prepared for danger. They know that they are a disadvantaged group on the road, so they must take protective measures before riding a bicycle and never rush to the road with motor vehicles. 10. Cyclists are the most attentive people. If there is something wrong with their car, they will find it out. Likewise, if their beloved girl is in a bad mood, they will definitely find ways to make her happy. 11. Cyclists are the most passionate people. When they see the same cyclists on the road, they will definitely wave their hands and face them with a smile. 12. Cyclists are the most optimistic people. If they encounter any troubles, as long as they ride to the West Lake to blow the air, all troubles will disappear, and then they will say to themselves: There is no hurdle in this world that cannot be crossed.
1. Bicycle is one of the best tools to overcome heart function problems. More than half of the people in the world die of heart disease. The exercise of leg muscles when riding a bicycle can help lower limb venous blood return, increase the pressure difference between the entrance and exit of the capillary network, promote blood return, and promote blood return. In fact, it also strengthens the microvascular tissue, which is called “collateral circulation.” Strengthening the blood vessels can keep you from the threat of age and stay young forever. 2. Habitual cycling exercise can strengthen your heart. Otherwise, the blood vessels are getting thinner and the heart function is getting weaker and weaker. In old age, you will experience the troubles it brings, and then you will discover how perfect cycling is. Cycling is a sport that requires a lot of oxygen. There was once an elderly person who completed a 460km bicycle trip in 6 days. He said: “Older people must exercise at least 3 times a week to strengthen the heart and restore normal function. You must make the heartbeat fiercely, but not for too long. A good heart allows you to adapt to emergencies, such as driving or resisting. Dilemma.” 3. Cycling can also prevent high blood pressure, which is sometimes more effective than drugs. It can also prevent weight gain, hardening of blood vessels, and strengthen bones. Bicycles eliminate the need for drugs to maintain your health and are harmless. 4. Bicycle is a tool for weight loss According to statistics, a person weighing 75 kilograms, riding 100 kilometers at a speed of 20 kilometers per hour, can reduce their weight by half a kilogram, but they must be consistent every day. 5. Cycling can not only lose weight but also make your figure more symmetrical and charming. People who use exercise to lose weight, or those who exercise while dieting, are in better shape and more attractive than those who only rely on diet to lose weight. I don’t know how to describe “more charming”, but in fact, people with strong muscles and small ankles trained by cycling are always better-looking than people with haggard and bulging veins. Right! Proper exercise can secrete a hormone, which makes you cheerful and happy. From experience, we know that cycling can produce this hormone.
A cyclist who wants to succeed must not only make his cycling posture very aerodynamic but also improve his pedaling efficiency. In addition, pedaling symmetry is also something that cyclists need to pay attention to. In addition to affecting our cycling efficiency, pedaling symmetry may also affect our physical health. Cycling is not a sport with very demanding technical requirements, but this does not mean that cycling technology is not important. Mastering the correct gear ratio, maintaining an efficient pedaling rhythm, and reducing the physical consumption of cycling are the basic skills that all cyclists who want to ride farther and faster must master. If you want to get good results in the time trial, you have to learn how to make your posture more in line with the requirements of aerodynamics and minimize the resistance to forward. Anyway, although the above is very important, there are some details that we can not ignore, that is the stamping itself. As far as the essence of pedaling is concerned, the most perfect pedaling is to draw a circle. Through the combination of locking pedals and locking shoes, the trajectory of your muscles and joints has been determined by the height of the seat cushion, the position of the hip joint, and the position of the foot. As long as your cranks are equal in length on both sides, then Your pedaling dynamics are symmetrical. However, if you look at each stepping from a biomechanical point of view, the truth is not as good as you think. Everyone’s pedaling action on the bicycle is not necessarily completely symmetrical. Simply put, your left leg may use more force than your right leg. This will lead to two results: you may feel tired prematurely during long-distance cycling (in fact, you can ride farther! JAY note), and secondly, different pedaling power output will make your body lose balance, Brings a higher chance of injury. How unbalanced? The difference in strength between the left leg and the right leg can be very large in the pedaling special study. In a set of research data, six rigorously trained male athletes used SRM power meters to simulate a 40-kilometer time trial to test the pedaling strength of their left and right legs. The experimental results show that the power on the left and right sides is not balanced, with an average difference of 13%-17%. In the final stage of the simulated time trial, all the drivers increased their cadence. At this time, the difference between the left and right feet was reduced. However, the dominant foot of each driver still dominates. Unbalanced power can lead to overuse and increase the chance of injury In another study of pedaling asymmetry, scientists conducted a biomechanical study of pedaling on 11 professional cyclists who often train for long and long-distance cycling. The average age of these cyclists is 53 years old, they have a wealth of cycling experience (the annual cycling distance is between 4,500 kilometers and 14,000 kilometers), and they think they have very good cycling skills. In addition, they have no continuity before participating in the research. Or realize that they may have a biomechanical asymmetry of the pedaling. These cyclists carried out an 18-minute ride test on a bicycle equipped with an SRM power meter. At the same time, they used a TACX power meter cycling platform and adjusted it to the best geometry according to the cyclist’s body. In the test, the pedaling force exerted on the left and right cranks of each tester can be recorded corresponding to the power output data. In this way, the pedaling force applied by each tester at each point in the pedaling process can be understood. Significance of improving pedaling symmetry The asymmetry of pedaling, apart from the increased risk of injury, the imbalance between the left and right legs will cause the body to feel fatigued prematurely. The stronger leg will compensate for the weaker leg with greater force. Maintaining power output is a less efficient way. In view of this result, it is of great significance for qualified drivers to test their pedaling biomechanics, improve pedaling efficiency and reduce the chance of injury. How to check the symmetry of leg strength Don’t “feel” symmetrical and just think it’s a balanced force. The feeling is generally inaccurate. You need accurate measurement and look at the data to analyze whether your left and right output power are balanced and smooth. Use accurate, power meters with left and right output tests, such as SRM, for accurate measurement. How to improve the symmetry of the legs If your left and right legs have a very obvious asymmetric pedaling output, then you need to carry out special strength training for the weak side to improve your pedaling symmetry, thereby increasing the pedaling efficiency. Lunge squats and side lunges are both very good methods. Through certain training, the output power difference of the legs is gradually reduced, and the symmetry of the output on both sides can be improved. Of course, it is also a good method to use a power meter on the cycling platform to perform pedaling force balance training on both sides (the power meter is required to test the output torque of the two legs separately). Your pedaling goal is to minimize the difference in output power between the left and right feet. This, like strength training, can effectively improve your pedaling imbalance.
