Extended data
Sports misunderstanding:
(1), the greater the exercise intensity, the better.
Doing too much beneficial exercise will be counterproductive. Experts point out that excessive exercise is dangerous. Especially those who have just started exercising, their bodies need rest and recovery. In fact, we hope to get positive results from exercise, which happens during the rest period. And after exercise to a certain extent, the effect will decline.
(2) Don't eat before exercise.
This question must vary from person to person. In fact, it may be better to start exercising after dinner. Doing some moderate exercise after meals will consume more calories than long-term exercise after meals. So it is medically reasonable to take a walk after meals.
(3) It is best to exercise in the morning.
