Chinese soldiers and armed police have less body fat, strong endurance, good physical strength and clear muscle lines, but generally lack girth, that is, "lean". Running, jumping, climbing, turning and other practical maneuvers are very strong, but the pure strength is very poor.

Speaking of it, this is actually related to the supply capacity of the troops. American soldiers are very big, and a person's weight is twice that of China soldiers. But such a body will consume much more energy to maintain physical strength and complete movements. Your individual soldiers can afford it, but the army can't afford it or won't buy it.

That's how China's army was trained. If you want to join the army, you'd better get used to it.

Push-ups can develop pectoralis major, deltoid toe and triceps brachii to some extent. However, if you gasp quickly and your muscles are not fully stimulated, the exercise effect will gradually weaken with the enhancement of your physical strength and endurance, and your muscles will stagnate when they develop to a certain extent. Push-up load is small. Doing one hundred at a time is good for the development of muscle endurance, but it won't grow big and thick chest muscles. Big shots must be stimulated with heavy objects.

To lose weight, aerobic exercise must last for more than 40 minutes. If you can do push-ups for 40 minutes without rest, you can lose weight.
