Intensity – not an end in itself but a tool they need to use caution. The key to optimum intensity – to receive periods of training. Explain what it is. All of your work in the gym should be divided into periods. Assume first nizkobemnye training (due to the number of sets and repetitions), followed by high-intensity (weight and effort). This scheme gives good performance and, incidentally, a considerable gain in time (do not have to then terminate employment because of overtraining). It is clear that the catabolic effect of cortisol under such a scheme – is minimal. Changes in the muscles and their controlling neurons in literate 'NATURAL' increased strength and power.

In science, such changes are called neuromuscular adaptation. Curiously, this process is no 'ceiling' for example, some weight lifters can constantly improve the result, without leaving out of his weight class. We often hear such recommendation from the 'experienced' coaches: build up, say, force and muscle itself will increase. There is even a saying: 'Strong muscles – more' mass'. It would seem that everything is correct, that's only logic here is lame: strong muscle, as is known, is not necessarily a big one! We return to the neuromuscular changes. Adaptation – the result of increasing the rate of appearance of additional motor units (the so-called bundles of muscle fibers, 'Run' one neuron) – on the one hand, and an increase in the rate of muscle contractions – with the other. As 'teach' the nervous system to create as many additional motor units? How to make the muscles contract faster? In these two matters secret of strength and power.
