This happens: first, it may be because the body has just participated in sports and has not adapted to this change for the time being, leading to insomnia; Second, maybe you can't sleep because you exercise late and your body is still excited when you sleep. If so, I suggest you listen to some relaxing music before going to bed to fully relax yourself. Drinking a glass of milk before going to bed is good for sleep.

If your body doesn't adapt, it will get better over time. At the same time, for the sake of your health, I hope you can consult a professional bodybuilder and work out a suitable exercise program. This will be better for your health!
