is proposed in two variants: that mainly both from sitting with barbell on his shoulders.
The main purpose is the stimulation of the abdominal muscles with the aim to decrease the waist and reducing localized adipose tissue.
BUT THAT'S WILL?
We start from 'anatomy and biomechanics from the beginning by saying that all our vertebrae while having common characteristics are substantial differences, depending on the level to which they belong, greatly influencing the physiology and the possibility of movement. A thoracic vertebra and a lumbar vertebra have similar characteristics but of completely different orientations which entails very different dynamics during the same rotation movement. In the lumbar vertebra in fact the anatomical conformation determines a movement that is not pure rotation but of -scivolamento rotation, a pairing that urges the intervertebral disk is not rotating but in cutting force. In a nutshell characteristics for the thoracic vertebra can be influenced by rotational movements instead of the lumbar vertebrae suffer excessively such movement in a negative way. In light of these trends, we can say that the rotary work done much to chest level and at lower levels as it is believed;
also requires the exercise of the lumbar spine a movement that presume are already is not able to make and it tests the strength of potentially risky disk cutting.
LA's icing on the cake:
also make matters worse torsion movements do not occur against gravity and this results in a paltry muscle stimulation negligible to purpose of toning the waist.
better standing or sitting?
twists bust standing are far less risky especially if followed with stick, ie a virtually non-existent load. In this variant, in fact, the movement is often composed and unbeknownst to the subject by a twisting of the spine associated with a rotation of the hips. At the sitting version instead leaves little escape: the constraint given by the stopper reservoir prevents any kind of hip rotation compensation by increasing the risks of susceptible species or advanced age.
at this point I feel quietly recommending this are aesthetic model maker is a reinforcement Buddhist.
If you want to get more results properly training the obliques basated on two principles of common sense two points work against gravity and very limited excursions.
