Not exercising for half a year

Because you don't exercise for a long time, plus the amount of exercise of 1, the amount of exercise may be a bit large, and various functions of the body can't bear it. This should be done step by step. Set the amount of exercise less first, and then increase it bit by bit, just like fitness. It is impossible to say that people's health can't stand it if their weight reaches the limit directly, and it is more harmful to the body.
