The key is that swimming can make people feel comfortable, but paying attention to posture, such as breaststroke, can easily cause meniscus injury.
Cycling is also a good way to exercise. If you go out to ride a bike, you can also see the scenery along the way. If you are in a gym, you can also pay attention to adjusting the position of the seat. Also, don't ride fast and hard. Although this kind of exercise does little harm to the knee, strenuous exercise is different and counterproductive.
Compared with running, walking is a kind of exercise to protect your knees, and it can also achieve the effect of exercise. If you walk normally for a while, you can sit down and have a rest. If your body is obviously tired, you must sit down and rest. Don't force yourself. Because if you force yourself to exercise, it is easy to have problems, especially for fat people. Scientific weight loss is the key!
