I've heard of belly wraps before. A lot of Asian women use a belly wrap after they have children. Usually they use some type of material to wrap around their belly and it helps to loose the sag women have after having a baby. This works because it helps put everything back in place (which is knocked out of place when pregnant). Also, the belly sweats which helps to loose fat also. But many Asian women have told me this works, and has been done for years.
