All training methods are not blindly following the trend. Some fitness exercises are aimed at one person and may be harmful to another, so we should keep fit scientifically. How can we do scientific exercise? Take the question raised by the subject as an example. Good friends of middle-aged and elderly people should first find out whether the tendons are short when stretching their legs, splitting tendons and pressing tendons. Is it really necessary? Can this solve the problem to be solved? Will there be any harm? Analyze this action, stretch your legs, separate tendons and press tendons, and focus on pulling the muscles on the back of thighs and calves. This action will expand the tension of the muscles, tendons and articular cartilage at the back of the leg, and expand the pressure of the femoral neck outside the kneecap and the energy of meniscus extrusion. If the muscles in the front of the thigh are too tight, splitting is equivalent to adding fuel to the fire, which will make the femoral neck press against the lower end of the femur.

After a long time, it will also cause chondromalacia patellae. If friends with knee hyperextension continue to do splits, it will aggravate the work pressure before the meniscus. Knee osteoarthritis, ligament injury, it is more necessary to choose this posture carefully. However, for people who are absolutely anxious about the muscles of the posterior thigh, this action is a good simple and effective action. Warm-up stretching exercise itself is a kind of fitness exercise, which is good for the body. Most middle-aged and elderly people do these actions in synchronization with other fitness exercises, which can play a greater role in the body.

Middle-aged and elderly people have nothing to do, relax muscles, press the bed in leg press, and exercise bones and muscles, which is good for health. "Running water does not rot, and the human body will make it move." Regular exercise will accelerate the blood circulation of the body, improve the basic metabolism in the body, and be beneficial to physical and mental health. In addition, it can also improve the agility of joints, deal with the adhesion between muscles and muscle fascia, and maintain their elasticity and support. There are also some middle-aged and elderly people who usually exercise by walking, running, practicing boxing, playing basketball and playing fitness equipment. I will do warm-up exercises during exercise, and I will often do stretching exercises after exercise. Warm-up plays a role in awakening the body and transforming the body from a static state to a moving state as soon as possible.

Make muscle tissue warm, make bones and joints flexible, and make the heartbeat rise. It can improve sports performance and prevent knee joint injury caused by sudden fitness exercise. It is to press tendons, reduce muscle tension, muscle stiffness and swelling, and let the human body release pressure easily. It is pressing tendons that can make it easier for body joints to twist their heads or stretch their legs in a wide range … these activities or fitness exercises. Pressing tendons can also prevent muscle sprain or contusion. Young people, in particular, must remember to press tendons before high-intensity exercise. Pressing tendons should be moderate, not too much. All sports activities need moderation. Especially for middle-aged and elderly people, it is necessary to consider the measurement and amplitude of their tendons according to their physical conditions, so as to feel the benefits of tendons and blood vessels brought by lacing.
