Everyone will wear knee joints when exercising and walking, but they can recover themselves after rest.
However, obese people are heavier, and the pressure on their knees during exercise is higher than that of ordinary people. It is easier to bruise joints than ordinary people, leading to ankle joint swelling and pain, knee joint inflammation and so on.
Therefore, obese people should reduce the exercise that compresses the knee joint, such as squatting, skipping rope and running. This kind of exercise produces several times more pressure than standing, which causes serious pressure on the knee joint. You can choose swimming, cycling, etc. Instead, pay attention to strengthening the training of thigh strength to share the pressure of knee joint.
