When done properly, waist training will provide long-term results. With time and proper use, your body will transform into the desirable shape by gradually changing the movement of the diaphragm (just like having hiccups) and pushing the intestines around a bit (just like being pregnant). This was proven by taking an MRI of German burlesque star Eden Berlin. Crazy as it sounds, this is not harmful to your body and in fact exerts less internal pressure on organs than pregnancy. Over time, through proper waist training, the 11th and 12th (floating) ribs will take on the desired shape and retain it for long-term results.
