In fact, it is really simple to go from thick back to thin back swan neck. I personally tested the super shoulder exercises. Two strokes, swan neck. Two movements form a swan neck. The first movement, arms crossed and raised, left hand in front, brought back a little by the strength of scapula, then brought down right hand in back and front, and made three groups 15. Please retract the protruding abdomen and cooperate with breathing.

In the second movement, the scapula is stretched backwards, and the arm is pushed backwards with the strength of the scapula. The left and right 15 are a group of three groups, but remember not to move the core and trunk. Practice quickly!
