Abstract: A support belt for labores provides increased support for abdominal muscles and back muscles in the lumbar region, particularly for those engaged in work involving lifting. The support belt includes a primary band adapted to extend around the user's waist and a secondary band. The secondary band is made of an elastic material and is adapted to stretch in a longitudinal direction to extend around the user's waist. The ends of the secondary band can be overlapped and secured to one another when the secondary band is in a stretched condition. By stretching the secondary band, the tension forces in the secondary band provide support for the wearer's back and abdominal muscles and helps avoid excessive curvature of the spine during lifting. To assure that the proper support is provided, the secondary band includes color indicating means for indicating when the proper amount of tension is applied to the secondary band.
