The answer upstairs is very good ~ Stick to it, the landlord will develop a very beautiful scapula ~ Allow me to add ~ Below the scapula and above the lower back can be improved by pulling down in front of the neck, 15-20/ group, 3 groups at a time, with the interval between each group not exceeding 1 minute, and then the lower back. There are two methods, one is prone, the hind legs are straight and fixed together, and the hands are held behind the waist. The number of groups is the same as above. Another method is to use a barbell, with the body upright, legs slightly wider than the shoulders, and hands holding the barbell in advance, with the distance being shoulder width. When exhaling, bend down and lift the front side of your body straight. When inhaling, get up. The number of arrays is the same as above.
