Exercise is good, but these four exercise habits need to be corrected immediately. Exercise is one of the ways to maintain good health, especially in recent years. With the enrichment of diets, the obese population is growing. Fortunately, people are aware of the harm obesity causes to the body, so they use exercise to lose weight. However, blindly engaging in exercise can easily damage the knees. This is especially true for older people, who often have calcium deficiency and more fragile joints. If they continue to do unsuitable exercises, it will inevitably cause joint damage. Therefore, we remind everyone that if your exercise has the above characteristics, please correct them immediately. 1. Neglecting warm-up: Surveys show that many people who exercise regularly neglect the preparation of warming up before exercise. Some people even think that running a few steps before exercise is enough to warm up. In fact, these behaviors are signs of inadequate warm-up. Therefore, it is recommended that everyone warm up before any kind of exercise. This not only relaxes muscles but also acts as a buffer, allowing the body to better adapt to the change from a resting state to an active state. 2. Excessive Exercise: In recent years, many people seem to pursue the goal of exercising for longer periods and taking more steps. However, what many don't realize is that exercise should be moderate. Doing too much can be detrimental to health. In fact, those who only focus on exercise duration and steps tend to overlook the fundamental purpose of exercise. Blindly increasing exercise volume will inevitably put pressure on the knees, leading to joint inflammation. 3. Hiking or Climbing Stairs: In people's traditional understanding, hiking and climbing stairs are excellent aerobic exercises that can strengthen the muscles of the thighs and buttocks and help improve cardiovascular function. However, various cases have shown that doing this exercise frequently can actually harm the body. This is because hiking or climbing stairs are weight-bearing exercises, in which case the joints below the waist bear a greater weight. First, when climbing stairs, the body's load is about four times the normal weight. In short, if a person weighs 60 kilograms, the load on the knees instantly becomes 240 kilograms when hiking or climbing stairs. Furthermore, the wear and tear on the knees caused by this type of exercise is irreparable. Over time, the wear and tear worsens, inevitably leading to joint problems. 4. Sudden Running: For people who don't exercise much, suddenly starting to run after a planned workout can be unhealthy and can damage the knee joint. Because leg muscles are weaker when exercise is limited, sudden exercise can cause instability in the knee joint. Especially when running suddenly on hard surfaces, the impact on the knee joint is greater with each foot strike. Therefore, it's best to choose a rubberized track for running. In short, while exercise is essential for improving physical fitness, incorrect methods can be counterproductive. For example, if you are currently practicing the four exercise habits mentioned above, please correct them immediately. At the same time, those who sit cross-legged for long periods should also immediately change this habit. When sitting cross-legged, the knee joint is in a bent position and bears a downward force under gravity, causing uneven stress on the inner and outer sides. Over time, this can easily lead to joint deformities.
