Proper exercise will bring health. Don't blindly pursue the sense of muscle, which is flashy. Life will be more perfect only if you are healthy. You can go to the hospital for a check-up, which may be caused by heavy physical load or lack of nutrition. I hope you get farther and farther on the road of fitness, and your muscles cramp, mainly because of excessive running and exercise. It's also calcium loss and cramps. I usually drink more milk and tofu. Fish and shrimp. Seafood.

Go to the hospital and ask the doctor for advice first. Stretch after exercise, it's hard for you to pull yourself away. Get a coach to help you pull it (generally speaking, the coaches in the gym have known or been familiar with it for many years). Muscles that don't stretch often are very tense and prone to cramps. Most of the cramps are related to muscles, nerves or blood vessels, and a few may be caused by drugs for chronic diseases (such as diuretics and hypolipidemics), because this will keep water in the limbs, resulting in imbalance of salt in the body, which is more likely to cause cramps.

Some cramps are called muscle spasms, mostly in the calf, so they are also called gastrocnemius spasms, some occur in the thigh, and rarely occur in other places. Accurately speaking, cramp is not a pure muscle cramp, but the tendon and muscle spasm and contract at the same time, making the limbs unable to stretch. Overtraining? Muscle fiber trauma/minimally invasive is too frequent, resulting in muscle decomposition state greater than synthesis state, excessive nutrient loss, and may be accompanied by cramps.

Under normal circumstances, sleeping at night should be the time for the human body to recover itself. At this time, the human body relaxes and the blood flows back to the liver to hide. Should be conscious, if you often find yourself having leg cramps when you sleep at night, don't ignore liver blood deficiency at this time.

When calcium is deficient, this normal proportion is disturbed, which can directly affect the abnormality of nerve sensitivity, increase the excitability of neuromuscular, and the contraction of muscle and the transmission of nerve impulse can not be maintained normally, thus causing muscle convulsion, which is also commonly known as cramp.
