Generally speaking, an hour to an hour and a half of exercise is appropriate, but the fitness effect varies from person to person. Everyone's body fat, metabolic rate, fat content and personal physique are different, and the effect will definitely be different. Moreover, there is no very accurate exercise time in the world, and the best exercise time is the one that suits you. Sometimes you still have to experiment and try to know the most suitable exercise time for yourself.

In the process of exercise, try not to do the same fitness program every time, but switch as much as possible, because if you repeat a fitness exercise frequently, it is easy for our muscles to remember that the effect of the next exercise will gradually be lower than the last one. At the same time, you can adjust the number of movements each time, and try not to be the same as the previous movements, so that you can exercise your muscles better and promote fitness to achieve faster results.

Also, pay attention to replenish water during exercise. Fitness is a particularly exhausting exercise, so be sure to drink water. In addition, attention should be paid to the supplement of energy and nutrition during exercise. If you don't eat, it is easy to faint during exercise and produce hypoglycemia.

Finally, fitness is something that needs long-term persistence. With the right exercise time and exercise method, we should still pay attention to persistence. Many people fail in fitness because they don't insist. They do it today and give up halfway tomorrow because of laziness or other excuses. The fitness effect is definitely not good, so all that matters is persistence. Another small suggestion is that if we don't have a whole period of time to exercise, we can adopt the method of dividing it into several time periods.
