It supposed to be for chest and lats.

You start with your hands up and lower them in your sides until they touch side of your thights.

This 180degree movement is quite long and im wondering is it lats who is strongest mover in whole process? Or is some muscle stronly assisting it at some degree point like chest? Also how much is posterior delt involved in exrx site it says that it isnt involved at all.

Lats are the most like the most working muscle there. Pecs are assisting as well. The shoulder muscles are more in a stabilizing and antagonising role on this one, because especially the middle and front delts are supposed to abduct the humerus. The rotator cuff muscles also are more in the stabilizing role on the exercise. Supraspinatus is also the antagonist on adduction. Also working on the exercise is biceps and a less known muscle near the biceps called coracobrachialis. They both assist on the adduction of the humerus.

I don't really see a huge point of doing this kind of exercise tho. There are way more better ways to train the lats and pecs.
