I am also a fitness enthusiast. It is unscientific to just count the time to lose weight. Exercise needs to be systematic. It is more difficult to lose weight only, because fat is not only accumulated in the stomach, but also in all parts of the body. Let's not talk about these things. I'll give you some advice based on my experience: it's best to choose the exercise time from 3 pm to 4 pm (because this time is the most easy time for body muscles to get excited and receive), followed by 6 pm or 7 pm. Eat a small amount of food before exercise, such as a small bowl of porridge or a cup of protein powder. Start exercising after 30 minutes, first do 30 minutes of moderate-intensity aerobic exercise (running, cycling).
