Abstract: A back support belt comprising a primary support belt including fasteners for fastening the same generally at the frontal area of the waist of the wearer, and a secondary tensioning belt comprising fasteners for fastening the same around the primary support belt generally at the frontal area of the waist of the wearer is provided, and includes back support belt color tensioning indicators on the secondary tensioning belt which are visible only from the rear and side areas of the waist of the wearer, and thus not by the wearer, and which are operable to indicate both when the back support belt is properly tensioned around the waist of the wearer, and when the back support belt is not properly tensioned around the waist of the wearer. The back support belt color tensioning indicators are operable to indicate proper and improper tensioning of the support belt independently of the relationship between the size of the support belt and the waist size of the wearer to thus be virtually foolproof in operation.
