Started using goodarch on march 2012 until now about 1.5 years...
this is a photo taken by goodarch salesman comparing my posture, as you can see, my hips are are bend and my legs are Oshaped.
But maybe it's bcoz of the pants....?
During the period, I also went to JKl, a Chinese sort of massage for approximately less than 10 times (not really a massage, they r like pushing my spine...)
So I'm not sure which one helped me, or actually works, but for now my o shaped legs is still ther, n I feel like one side of my hip are heavier than the other.... feel free to ask me for enquiries.
