Shoulder Training

, mostly due to the so-called subacromial conflict (impingement syndrome). In addition to inflammation and the functional limit, it can be associated with calcifications, thinning, ruptures, etc. Immediately after we find the arthritic conditions, some of which may require the implantation of a shoulder prosthesis - in this case, the restoration of the 100% functionality is very difficult, especially in the application of a reverse prosthesis.

For all these reasons, it is good to remember that the "training of the shoulders - but also that of the chest and back, which exploit greater loads - is always very delicate and subordinates to the so-called" joint form ".

In this article we will try to better understand how to train the shoulders. We will not only talk about the system or method - which is the same for general hypertrophy - and we will not even describe the execution techniques in too much detail - which would require a tutorial - but instead we will offer useful insights to understand how to choose the exercises and above all why .

For further information: Back Training they are closely related and a single small chiasmatic space - through which the cephalic vein passes - prevents the two muscles from forming a continuous muscle mass;

Acromial (central, pars acromialis): arising from the upper surface of the scapular acromion;

Spinal (posterior, pars scapularis): starting from the lower lip of the posterior edge of the spine of the scapula.

However, electromyography suggests that it is made up of at least seven groups that can be independently coordinated by the nervous system.

A study of 30 subjects revealed an average mass for each individual deltoid of 191.9 g in humans, which ranged from 84 g to 366 g [Potau, JM; Bardina, X; Ciurana, N; Camprubí, D.
