Weightlifting belt
Weightlifting belts are used during weightlifting, powerlifting, and less frequently during weight training and strength training. Additionally, they are sometimes employed by employees in industrial settings. In these work environments, the equipment is usually called a back belt or back support belt.
The purpose of a weight lifting belt is twofold: it reduces stress on the lower back muscles by allowing the lifter to safely increase intra-abdominal pressure, and it increases the lifter's proprioception which may lead to a decrease in lumbar hyperextension and other forms of spinal deformation.
