Effective high-quality sleep can relieve the body muscle pain caused by fitness. Soreness is actually that the muscles we have exercised are repaired through sleep. If you don't have a good sleep, then your muscles can't be repaired well. Therefore, in order to make the exercised muscles less sore, it is necessary to ensure a good sleep.

② For people who want to exercise muscles through fitness, those damaged muscles can only be repaired and grown best during sleep, so lack of sleep will lead to the decline of muscle repair ability and seriously affect the efficiency of muscle gain.

A good sleep can help us concentrate on the next day's training, just like studying. Only by paying full attention can we seriously carry out every training and make the training achieve the best effect, so as not to waste time and energy. Excessive staying up late will reduce the rapid secretion of thyroid gland in human body, leading to lower metabolic efficiency, which is very difficult for people who want to lose weight through fitness.

Adequate sleep can make our spirit more pleasant. Studies have shown that adequate sleep can enrich people's spirit and delight people's body and mind. When we do something more happily, we often get twice the result with half the effort, and so does fitness. Adequate sleep and proper rest are the nutrients in our fitness process.
