If the hip joint is not active enough, many postures that need to open the hip joint will cause excessive pressure on the knee joint and make the knee joint overwhelmed. At first, you can rotate your hips and ankles, and practice butterfly and cow face poses. To strengthen the extension of your hip joint. After the hip joint is opened, it is much easier to sit in a pan and other positions. 2. Strengthen the protection of the knee through the balanced pose. Experts said that in the balanced pose, because the body needs to adjust itself to find the best position, at this time, the wisdom of the body will rationally use the muscles and ligaments around the knee to find a balance point. In particular, the standing balance type that needs to bend your knees, such as the eagle type, has the best effect. This dynamic balance is mainly through strengthening the function of ligaments, not just muscle strength, so it also helps to prevent future injuries. 3, pay attention to the subtle feeling of the knee, timely adjust the ligaments and cartilage of the knee and the meniscus are not very sensitive places, if you feel pain, at this time, the injury is often inevitable. So you should feel it carefully. Once you feel a little uncomfortable, adjust it quickly to avoid causing more harm. If you feel pain when you come out of the pose, the injury has actually been done. 4. Avoid overstretching your knees. Experts say that it is easy for your knees to overstretch inward in a posture that requires your legs to be straight. For example, the position of the knee tends to tilt inward in triangle type and leg extension type, and the ligament strength around the knee is easy to be unbalanced at this time. In standing posture, you can bend your knees slightly so that the soles of your feet are evenly close to the ground. In sitting position, you can put a small towel roll under the knee socket. 5. In the kneeling pose, keep your knees and ankles vertical. In the kneeling pose, keep the knees and ankles vertical. For example, warrior pose and side angle pose, let the knee be directly above the ankle joint and open the five toes. After bending your knees, the position of the patella should be consistent with the direction of the second toe. If you lean forward a little, don't let your knees exceed your toes. At the same time, pay attention to the instep, and don't let the instep fall. 6. The adjustment and construction of posture begins with the placement of feet. Experts point out that to ensure that your sole can touch the ground stably, the four corners of the sole (two points on both sides of the forefoot and two points on both sides of the heel) should be evenly distributed on the ground. Force. Strength goes deep into the ground through the ball of the sole of your foot, and your toes are as wide as possible to keep moving. At the same time, pay attention to the arch of the foot. In this way, the stress on the ligaments on both sides of the knee joint is evenly distributed, the patella can move freely, and the meniscus is not easy to be over-squeezed. 7. Pay attention to the active use of auxiliary items. When sitting cross-legged, if the height of the knee exceeds the crotch, a brick or blanket should be placed under the hip to at least make the height of the knee parallel to the crotch. When the hero is sitting, he can also put a cushion under his hips. If you can't put your hips on your heels, you can put a rolled towel between your thighs and calves. In any pose that requires deep knee flexion, such as children's pose and Maric pose, you can roll a towel near the knee socket and sit down, which can greatly reduce the pressure on your knee without damaging it. 8. Pay attention to relaxation after practice. Experts say that relaxation after practice is very important and can help muscles, ligaments and bones recover well.
