The so-called soldier training and muscle exercise are different. Muscle training is to repeatedly practice with heavy or overweight weights in the same place in a short period of time to stimulate muscles, which is actually beyond the natural endurance of ordinary people, because no one will carry a dozen or twenty kilograms of dumbbells forward or run around with hundreds of kilograms of barbells. In this way, after 1-2 days of rest and dietary supplement, hormone secretion increased, muscle recovered, size increased, and so on. Training as a soldier is nothing more than unarmed training. Even if the amount of time is relatively large, it can be regarded as a normal category under natural conditions and enhance endurance.
