This method works quickly, but the effect is not obvious after 5 days. I must stick to my own experience.

1 Stand up straight, and your hands are naturally perpendicular to your sides.

Walk out of your left leg with a lunge, raise your hands above your head, cross your fingers, palm up, and pull up as much as possible.

3 lean forward as far as possible, put your hands together and straighten forward as far as possible, adjust your breathing and keep it for 20 seconds, just like the second action of changing sides.

Thin arms persist for a week and the effect is obvious.

Put your hands behind your back.

2 Turn the downward hand slowly upward, so that the fingertips are upward. Be careful not to spread your hands when flipping. One side of the little finger is close to the spine. When the hand is pushed up to the shoulder, the arm has a feeling of pulling up. Adjust breathing and keep it at 1 min. Restore 5 to 8 times.

The method of thin abdomen should also be adhered to.

1 Lie flat and lift your feet at right angles.

Put your hands behind your neck, gently hold out your chest and exhale until your elbow touches your knee, then slowly let go, but don't touch the ground and inhale at the same time. Repeat 3-4 times, 30 times each time. Hehe, it takes a lot of perseverance.

Almost effective. That's all I have, hehe
