Q: It is said that running and climbing stairs are not suitable for fat exercise? Then which aerobic suitable for fat weight people exercise? A: Climbing and running are really not suitable for people with a large weight base, because the pressure on the joints is relatively large. Obese people are suitable for low-impact aerobic exercise. Low-impact exercise is the movement of less pressure on the joints, such as elliptical bicycle swimming. In order to reduce the lower back pain that may be caused by abdominal fat, obese people also need to strengthen some core training and lower extremity stability training. Some mat and fitness ball core and lower extremity training is quite good, the pressure on the joints is small. In addition, in addition to running and climbing stairs, obese people should also avoid some high intermittent jumping and squatting exercises, and then do such exercises when the body weight is reduced and the body stability is good and the fitness is up. Q: If I wear knee pads and running shoes with shock absorbing function, is it also impossible to avoid the injury to the knee joint of large weight base? A: This is not recommended. Although shock-absorbing shoes reduce the impact pressure on the bottom of the foot, but it is also because of this shock-absorbing function that weakens the sensation and response of the plantar receptors to the outside world, the foot lands as it pleases, which will cause bad running posture, and this vibration will still be transmitted to the joints, causing injury. Knee pads can protect joint stability, but it is not recommended to always bring, long distance running or fatigue downhill protection use, but daily exercise as far as possible to train the body’s self-regulation function. For obese people who want to run, it is recommended to lose weight first. Q: What are the exercises that are less stressful to the knee? I have had meniscus surgery on my right knee and I am currently six months post-op. I want to slowly resume exercising. I used to enjoy playing ball, but now I can’t jump and feel weak. A: Two kinds of exercises are recommended for those who have had knee surgery. Swimming and Pilates. Swimming, especially freestyle is less stressful to the knee joint. Pilates is a mat exercise, originated from sports rehabilitation, exercises body control and strength, and also has little pressure on the joints. You can learn about it and try it. The principle of post-operative knee rehabilitation and knee joint protection is to try not to let the weight load directly on the legs, and to reduce the lower limb impact even more. So, swimming is most suitable. Other, such as dynamic cycling is also good ah, if the knee can withstand some strength, also try the elliptical machine. Why do you say cycling, the principle is very clear, is to let your buttocks have bearing force, the legs do not directly bear the weight. So, everyday cycling is a very suitable form of travel + exercise. But considering the feasibility, you can buy an adjustable resistance dynamic bike at home (a few hundred dollars), as for the intensity and rhythm, must be in accordance with their knee can withstand the intensity to adjust, not blindly follow the existing dynamic cycling music or video. As for the gym’s very high kind of dynamic cycling, too much emphasis on dynamic, easy to be driven by the atmosphere and movement over Mong, but may hurt the knee.
