The best state of human body-building exercise is from 2 pm to 6 pm, when all physiological functions of human body are at a high level. At this time, exercise can give full play to its own strength. At 2 o'clock in the afternoon, two hours after lunch, lunch is almost digested.

Moreover, even after training, there is a long time to supplement nutrition, and the time for supplementing nutrition twice is enough, which can better restore the body and does not affect sleep at night.

Generally speaking, you don't need to consider the body fat rate. If you are thin, you should think about it, even if you are fat. Fat is not useless in the body. If the fat is too low, the qi and blood of the human body will not be balanced, which is what Chinese medicine calls imbalance, which is not good for the body. And fat can protect muscles to some extent.

If it is pure aerobic training, one day 1 hour is enough for physical fitness, and people who lose fat should not exceed 2 hours a day. If there is still equipment training, 30 minutes to 1 hour after strength training is enough.
