Three elements of fitness: scientific training, adequate nutrition and adequate sleep are indispensable. There has always been a saying in the fitness field that "3 points depend on training and 7 points depend on recovery", which shows that recovery is more meaningful than training to some extent.

Muscle growth occurs outside of fitness. Strength training can destroy muscle fibers, and then make muscles recover and recover excessively through adequate nutrition and sleep, so as to achieve the purpose of increasing muscles. But in reality, many bodybuilders mainly focus on training, ignoring the importance of rest. After exhausting training and destroying muscle fibers, staying up late without a good rest is undoubtedly a secondary injury to the body. Imagine what effect this kind of fitness can have, and the result can only be counterproductive.

Hormones in the human body can promote muscle growth. Generally, the secretion of human hormones reaches the highest value at night112, which is also the best time for human self-growth and repair! If you often stay up late, it will inevitably affect the self-recovery process of muscles and fail to achieve the effect of fitness. Professional fitness athletes pay great attention to the importance of rest and ensure at least 1+7 sleep time every day, that is, 7 hours at night and 1 hour during the day.

Staying up late will also reduce immunity, memory, vision, skin damage and mental fatigue.

Practice, eating and sleeping are three important factors that affect the fitness effect of dumbbells, and practice is consumption and "destruction"; Eating is a supplement; Sleep is to build and repair muscle tissue. Ensuring adequate sleep and excessive muscle recovery after fitness exercise is the premise for bodybuilders to obtain the best effect of dumbbell fitness and maintain the best physical and mental state, because the adjustment and construction of the body are carried out in sleep.

Whether in summer or other seasons, bodybuilders must ensure adequate sleep, especially at noon, so that the body always has enough rest time. Specifically, make sure you have 8-9 hours of sleep every night. There should be 1-2 hours nap time before exercise in the afternoon.
