Squat exercise can exercise quadriceps femoris, lumbosacral muscles and pelvic muscles, which can play a certain role in losing weight; When squatting, the leg muscles contract, and the blood of the lower limbs will return to the heart faster, which will promote the blood circulation of the heart and lungs and reduce the incidence of coronary heart disease and stroke; If you squat with your back against the wall and your back is straight, you can exercise your back muscles, which has a good preventive and therapeutic effect on diseases such as lumbar muscle strain and disc herniation.

However, not everyone is suitable for squat. For example, when people reach middle age, most knee joints have degenerative diseases. If they have severe tearing or pain when squatting or getting up, they should be careful to squat.

There are many reasons for knee pain, such as rheumatism, strain, trauma, etc., but the more common is the metabolic degradation of bones and cartilage, which usually begins in middle age. Knee joint is the largest load-bearing joint in human body, and its surface lacks the protection of muscle tissue and is covered with cartilage.

When going upstairs, the weight of the knee joint is basically its own weight, while when going downstairs, the knee joint bears downward force besides its own weight, so the impact increases the wear on the knee joint. Squatting will also aggravate this kind of wear and tear, and the consequences may not appear immediately, but the consequences of wear and tear will appear in a few years or even longer.
