From 5 am to 7 am, the body began to wake up. At this time, you will soon be full of energy after getting up. Especially at 7 o'clock, the secretion of adrenocortical hormone enters a climax, and the immune function is strengthened, which is very suitable for exercise. From 8 am to 12 am, the nerves are most excited, and the memory, heart and enthusiasm are in the best state, so this time is suitable for work, study or travel, and no exercise is allowed. 1 From afternoon to 4 o'clock, especially in spring and summer, people are prone to fatigue and drowsiness. It's best to have a rest at this time and don't do too much exercise after lunch. At night, around 10, the body temperature begins to drop, drowsiness will come to you slowly, and the body function tends to be low, which is not suitable for strenuous exercise.
Many people think that fitness exercise is very simple. I go to the gym to work out. As long as I see what others are doing, I will do it. It's like a gourd painting gourd ladle, just waiting for yourself to exercise muscle health. But the wrong way of exercising is more terrible than not exercising, which will cause irreversible harm to the body.
In fact, even the "old driver" in the gym may be accidentally sprained or injured, and there are even cases in which people despise their bodies and cause death. So in the gym, you need to find a professional coach to guide you, and some dangerous sports even need someone to watch you.
