2, the principle of progressivity, whether it is strength, speed or movement difficulty, in the training process should be gradual, only in the low difficulty, low load, low speed state to do a hundred times, and then try to faster, heavier, more difficult training.

3, the principle of repetition, the human body is always in the metabolism, muscles, ligaments, bones, blood circulation, nerve conduction, energy supply and other systems are an organic, constantly changing whole.

As long as we have a little slack, the body will be like a car in an idle state - like into a state of rest, if long-term, the body will be like a car - like, not only will the engine carbon, even the transmission, cooling, brakes, air conditioning and other systems will be due to the lack of exercise and cattle failure.
