Tell the truth: you are not old! ! Now the world bodybuilding champions are bigger than you. You said I experienced insomnia and sweating at night, but I'm fine now. You didn't take any fitness supplements, did you? You and I exercise for the same time, but I exercise two places every day, and the intensity is very strong, without your symptoms. Do you have any diseases, high blood pressure or something? I suggest you rest for a few weeks and don't worry about muscle atrophy. Joe Kate (2006 bodybuilding champion) will rest for six weeks after the game, and his muscles will grow with proper nutrition. One of the symptoms in fitness is "sports phobia", that is, I am worried that I will give up all my efforts and not stop. As you said, the first few months were very tense. If you don't have enough nutrition, you may lose sleep because your muscles will stay excited. It is suggested to do less explosive movements during sports in the future. If you still exercise at night, don't skip aerobics. High-intensity exercise will continue your excitement. You can try some supplements: branched-chain amino acids and glutamine, which are good supplies for growing muscles and restoring physical strength to see fatigue. Because they are all essential amino acids for human body, there are no side effects.

And you should know whether you are fitness or bodybuilding. Fitness is to make yourself healthy. Bodybuilding does not mean health, because things such as eating habits required by bodybuilding do not meet the health standards.

I hope I can help you. Pay attention to nutrition in fitness!
