First of all, if the knee joint is injured, if it is not in a braking state, you can do some exercise to help the knee joint recover quickly and strengthen its toughness.
One: Aerobic training
If you want to do aerobic training, it is more suitable to suggest boating opportunities. Rowing machine can not only help you burn excess fat in your body, but also enhance the muscle strength of quadriceps. Because when rowing, you mainly use quadriceps, that is, the muscles on the front side of the thigh. These muscles are mainly responsible for knee movements and hip bending, making your legs more powerful. When your quadriceps is getting stronger, your running endurance will also increase.
Two: anaerobic training
If you want to do anaerobic training, you can also control your knee joint in a painless range. However, squat training is not recommended, and fixed equipment should be selected for muscle strength training. Such as: sitting posture, leg flexion and extension, backward pedaling, bending and leg flexion and extension. These fixing devices can flexibly adjust the weight range and provide some protection for your body relative to free weight. It is a very good training program. However, it should be noted that heavy weights should not be used blindly to avoid secondary injury to the knee joint.
This friend mentioned that exercise hurts my knee. I am used to physical exercise. If I don't exercise or sweat, I will feel uncomfortable. This is your habit of regular exercise. If you stop exercising, your body will not adapt. That's why you flinched. Many people do not pay attention to keeping their knees warm after sweating when choosing long-distance running, which will inevitably lead to knee pain. It is still recommended that you bring knee pads when running. Knee pads can keep your knees warm and protect them from injury. This friend mentioned that he wants to exercise more, but he can't make his injured knee hurt. Then you can choose to practice qigong or stand on piles for a short time! Because practicing Qigong and standing on piles also makes you sweat and feel comfortable, and you can recover your injured knee when you relax. This is the difference between people choosing health preservation and fitness now.
