It is a strength exercise focused on strengthening the broad dorsal, the rhomboid (located at the bottom of the nape of the neck), the middle trapezium and the brachial biceps. Basically, then, work your back and shoulders.
During the exercise, you should keep your feet on the ground at all times. The spinal column should be in a neutral position, with a slight inclination at the moment of the pull towards the chest, of approximately 70-80°.
The elbows should always look downwards, not backwards or sideways. The wider the grip, the more the broad dorsal will work.
