You can't lie down
If you have perseverance.
You can stand against the wall for half an hour.
Head and shoulders
buttock
hand
Keep your legs and heels close to the wall.
Can not help stovepipe, correct posture.
Effect is very good
After standing up, I hit my leg 200 times.
That's how I lost weight.
I also recommend you to try it.
It usually takes 10 to have obvious effect ~ ~ Come on ~ ~
When I was in college, I climbed stairs and wrapped in plastic wrap.
At least half an hour at a time.
It will take effect within a week.
