After a period of fitness, I feel more and more tired and bored, which may be related to anemia, blood pressure or blood sugar. I should go to the hospital for examination, find out the cause and then treat, drink more water, eat more foods rich in protein and vitamins, and don't stay up late to ensure sleep.

Keep exercising and feel exhausted. In this case, it is suggested that you take your temperature to see if you have a fever, improve your blood potassium and creatine kinase to determine whether you have hypokalemia or myopathy, and improve your electromyography to determine whether you have peripheral nerve injury. You can consult a neurologist.

The first reason: normal phenomenon.

The first reason is simple and comes from our normal phenomenon. Normal people generally feel weak after exercise.

On the contrary, it is strange that we still feel energetic after a fitness. If we still feel that we have a lot of strength after fitness, it may be that you haven't exercised enough. Try to add some weight and strength next time. Therefore, it is normal to feel general weakness after exercise, which may be due to the exhaustion of our own strength during exercise.

The second reason: excessive overdraft.

The second reason may be that we exercise too much during the exercise and our physical strength is overdrawn. In the process of exercise, choosing the wrong sports or choosing the strength beyond your ability will lead to excessive exercise. After exercise, our bodies will feel exhausted and have no strength at all.

If you have no strength after exercise, feel uncomfortable and don't want to exercise all your life, then you may have exercised too much, and you have overdrawn your physical strength and health. This has no fundamental impact on fitness, but it will affect our health. So please know yourself first, and then choose fitness programs and make plans for your fitness efforts.
