The muscle is contracted when the raised arms are pulled up. The best exercise for training the broad back muscle in weight training is therefore the

The latissimus pulls it down with his arm raised (latissimus pull). This adduction, retroverion and internal rotation take place during the recovery movements of litter and shock disciplines of athletics. In supported arms, the latissimus (M. latissimus dorsi) acts as a holder of the trunk.
The greatest strength unfolds the broad dorsal muscle (latissimus dorsi muscle) similar to the large pectoral muscle after a pre-stretching. This can be seen very well by the example of the stroke of a blow with the hatchet.
The athlete kneels and supports himself with one hand on the side. The other hand is held over the body in a similar way to the oblique abdominal muscles' stretching exercise. The body is tilted sideways, turning the upper body slightly inward.
