A person's optimal amount of exercise is closely related to gender, age and physical condition. Ordinary people take exercise as their purpose, and it is best that the single exercise time should not exceed 1 hour.
Generally, it can be analyzed through the determination of objective physiological indicators and the subjective feelings of exercisers, and then we can know whether the exercise plan is appropriate.
The best exercise time in a day is from 4 pm to 6 pm. At this time, when the materials for human eating are basically used up, we can exercise and keep fit, which can promote the decomposition of body fat, complete the actual effect of losing weight, and also convert body fat into muscle. Daily exercise takes 65,438+0 hours to make muscles and bones work, but we can't exercise with high toughness and overload.
When the fitness time is less than 25 minutes, the actual effect of exercise and fitness is not great; After 25~30 minutes, the body is slightly hot, and it just begins to digest and absorb heat, and the muscles and bones just start to exercise, which has a certain practical effect of exercise and fitness. More than 90 minutes will exceed the exercise intensity limit of ordinary people, which is very easy to get hurt. But the reality varies from person to person.
The most critical part of fitness exercise is actually the heart, and the muscles of the heart are the same. After exercise, they will become stronger and stronger. After a year of fitness, the heart rate will slow down, and the slower the heart rate, the longer the life span.
Exercise requires energy, but the energy stored in the body in the morning is not much, which can't meet the heat consumption of exercise. If you don't eat in time, exercise on an empty stomach, and exercise for a long time, it will cause insufficient storage of liver glycogen, a large amount of blood sugar consumption, leading to hypoglycemia, and may cause dizziness, palpitation, black eyes and other symptoms.
Fat doesn't grow in a day, and fat can't be reduced in a day. You can't eat a fat man in one bite. Don't set too big a goal at the beginning, set a small goal that you think you can really achieve first.
