A support garment assembly for supporting a lower back includes a belt that may be worn around a waist thereby facilitating the belt to extend along a lower back. The belt is comprised of a resiliently stretchable material to support the lower back thereby treating symptoms of a lower back injury. A strap is removably coupled to the belt and the strap extends beneath a crotch. In this way the strap inhibits the belt from riding upwardly on the waist.
