The Harbinger FlexFit Contour Belt is ergonomically designed to fit the natural shape of the body. The light, 6" wide belt provides comfortable support to stabilize the core muscles for weightlifting and allow full range of motion during functional strength training exercises. Wearing the belt during these activities can prevent injury and enhance performance. The overlapping design, with a rigid central panel and two kidney pockets, provides additional stability to enhance abdominal engagement and protect the back for safe lifting, while the flexible foam core and soft tricot lining offer comfort throughout even the most varied workouts. The adjustable, heavy-duty strap with heavy gauge steel tensioning buckle customizes 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.
