An abdominal and thoracic binder is used to provide support for back muscles and the abdomen of a user. The abdominal and thoracic binder includes a porous band, a fastener, a plurality of ventilation holes, and a plurality of reinforcing rods. The fastening layer is superimposed across and coextensive with the porous band. The porous band presses against the user's midsection and the fastening layer is exterior the porous band. The plurality of ventilation holes traverses through and is distributed across the porous band and the adhering layer, encouraging the breathability of the user's skin that is surrounded by the abdominal and thoracic binder. The plurality of reinforcing rods is detachably attached to the fastening layer and prevents the porous band and the fastening layer from folding. The abdominal and thoracic binder also includes a surface fastener that secures both the porous band and the fastening layer around the user.
