Search the Internet for "Swan Arms, Beautiful Ballet" and this video will come out. It is the action of the upper limbs, 14 is a little more, which is available on many video platforms. Pro-test, do it 20 times in 30 days, the effect of thinning the clavicle of the arm is obvious, and the photo comparison will be very obvious. It's been five months now, and I haven't done it 100 times. My thick shoulders have lost weight. I just need to stick to it!
