aspiration to progress of intensity should not affect correctness of performance of exercises. Each additional repetition and each increase of weight of a shell should be fulfilled "honestly" - only then your weight will grow together with growth of loadings. The correct equipment means very much and many.
And what is the correct equipment?
There are many different opinions in this respect. Personally I do not advise during repetitions to consider seconds: like, there are so much seconds on rise, it is so much on lowering. It will distract you from the main thing - from performance of the greatest possible number of repetitions provided by your "working" set. And here repetitions can be considered, without losing concentration. When you get used to trainings, you will keep count to repetitions subconsciously, without noticing that. And this calculation, certainly, is necessary as it will help you to hold in the head an ultimate goal all the time and to aspire constantly to it.
The first several repetitions in a set come easily so here you should not work at full capacity. If too "to try" at this stage, the bar will fly up too quickly, and it can lead to a trauma. But at the end of a set you have to "give all the best" really and watch closely that there was no chiting. The bar has to move measuredly - not 'drop" it! It does not matter that by the end of a set the speed of its movement can become much more slowly.
Between repetitions it is necessary to make a pause. In the beginning this pause will be very short - we will tell, one second. Then it will begin to be extended because by the end of a set you should take breath before each new repetition. At separate stages of training process and in separate exercises of a pause between repetitions it is possible to increase considerably.
At the end of a set, having accurately executed the necessary number of repetitions, you are able to afford one - two additional repetitions with a chiting, but only in some exercises. For example, at squats and stanovy draft avoid a chiting as fire.
If you have a skilled partner, can do in these exercises the forced repetitions. Carrying out presses lying, you can make the last repetition with a chiting, having slightly bent a back if with a waist you are all right. If the back can bring you, do the forced repetitions with the partner. However it is not necessary to be fond of the forced repetitions: at peak of a cycle it is quite enough of one - two in a final set of each exercise (and no more, than once a week).
So far it was talked of a standard manner of performance of exercises. But it is possible to carry out them and a little differently, for example, to reduce speed. Some conform to the rule" two seconds on rise, four on lowering"", and someone in general considers it only right speed. Sometimes apply also slower speed when on each repetition not less than fifteen seconds leave. Change of speed can bring a variety your trainings. But you should not abuse experiments, otherwise you will not manage to understand what way is better. Within one training cycle it is desirable to carry out the same exercises at the same speed, and the following cycle can be carried out slightly differently.
The efficiency of trainings is defined by the whole set of factors. Once you neglect one of them, and the efficiency of a training will fall. Progress of loadings in bodybuilding is the most important, but only at observance of the correct equipment and accounting of all other requirements.
