In general terms, the scientific basis behind the hypertrophic principle is the same as for any other muscle group. Therefore, to learn more, read the articles dedicated to muscle growth.
On the other hand, back training has some peculiarities and drawbacks, which deserve to be treated in a specific way.
, back training is undoubtedly one of the most "articulated".This is above all because the "back" includes over 1/3 of the body muscles, with functions that are also different from each other; this requires a diversification of stimuli - anything but simple organization - and a rather demanding training load.
In terms of strength, unlike almost all other muscles, those of the back cannot be effectively isolated. This means that their function can subordinate to the functional condition of other competitive districts.
Therefore, speaking of the great dorsal, large round and small round, it is evident that there are no exercises that are truly independent from the action of the flexors of the forearm, the posterior deltoids, the trapezius and the rhomboids. Any weakness of theirs affects the relative ability to train the back.
Also, being "less visible" than the chest, shoulders, arms, thighs, buttocks and abdomen, a large chunk of beginners tend to overlook it - superficial and overall counterproductive.
they are also recruited, in a different and often essential way, in the training of the lower limbs and the chest.A greater capacity for specific strength of the back muscles - responsible for the movements of the humerus, shoulder blades, rachis and pelvis - participates in the delivery of greater force even in complex movements, essential for the growth of loads and therefore hypertrophy ( think of the deadlift or deadlift).
Nevertheless, an "adequate awareness (nervous capacity, especially central) in the movement of the back muscles allows to reach a more advanced technical level, with considerable advantages once again on the expression of strength and hypertrophic development.
Furthermore, working together with the "rest" of the core, the back muscles firmly maintain the posture - also essential in everyday life.
