Harbinger Foam Core Weightlifting Belts are flexible and ultralight, with just the right degree of support to stabilize the core muscles and protect the back during heavy lifting. The belt is soft and comfortable, allowing full range of motion during functional strength training exercises. Wearing the belt during workouts that combine weight lifting and functional strength training can prevent injury and enhance performance. The breathable, plush tricot lining is soft against the skin and comfortable throughout even the most varied workouts. The adjustable, heavy-duty strap with heavy gauge steel tensioning buckle fastens securely, customizing the fit for optimum support and stabilization. Harbinger strength training belts are designed to be worn tight around the waist. The more secure the belt, the more support and stabilization it provides. Harbinger Women’s Foam Core Weightlifting Belts are available in three sizes, each designed to fit a range of waist measurements: X-Small fits 24-28 inches, Small fits 28-32 inches, and Medium fits 32-36 inches. Do not use pant size to determine the size of the weightlifting belt; measure around the waist between the hips and the ribs, starting and stopping at the belly button.
