When you choose to use a back support belt, you can't just throw it on any old way. First of all, you need to make sure it fits and has not lost its elasticity. A back support without elasticity is like a boot without laces. Once you have the belt around your waist, cinch it up as much as possible to avoid straining your back. The front of the brace should be near your navel and the back of the back support brace on your lower back.
