Number of sets and repetitions (Part 1)

The number of repetitions depends on your goal.

Heavy series (8-12) repetitions are generally more effective to work the volume. For the number of sets, 3 is enough to work well.

There are several factors for muscle gain, burning and congestion (when the muscles swell gorging blood) are the least productive use is more productive "heavy-duty".

Use heavy loads


It is therefore, necessary to define what these heavy loads, in fact according to the number of repetitions, we will train different aspects of performance:

- The heavy series, that is to say, with less than 5 repetitions, promote the development of the nervous system and therefore strength, not muscle mass because muscle fatigue is low due to the short duration of the series. So we will make short and heavy sets with long rest time, 3 to 5 minutes, to allow our bodies to reproduce the intensity of effort in order to increase its maximum strength.

- A heavy training corresponds to sets of 8 to 12 repetitions, it will promote muscle growth and not the nervous system. Indeed, nervous fatigue is less important, but the metabolic muscle strain is more, it allows a much more traumatic muscularly and therefore greater overcompensation work. We use rest periods long enough 1min30 to 3 minutes. This type of training is the most effective way to develop muscle mass and is the one most frequently used, it also increases the maximum force, but unless a program heavy series.

 
-A light workout is a workout of 12 reps and more. There are mainly promotes congestion and burning, and the focus is on the hormonal adjustment resulting from this type of training, indeed lactic acid for example is a precursor of testosterone. Moreover, these workouts are meant to improve the size of glycogen (carbohydrates present in the muscle) and thus slightly increase muscle mass. Rest time is short, from 30 seconds to 1 minute. Here, the nervous system is much less put to use and the charge is too low to allow the destruction of important muscle tissue, we focus mainly on the energy reserves of the muscle.

Be careful however, as an experienced practitioner can make a series of 10 with a heavy weight.
