Much like other lifting belts, the Harbinger lifting belt would offer you a roller bar enclosure system, which gives you more stability. Instead of the belt coming loose, you would have to release the roller bar for the belt to be loosened. Ideally, you would want to wrap the belt around your waist and lock the buckle. Once this is locked, you can engage your core, whilst expanding it into the cushioning of the belt. This would provide you with stability and the perfect size. It should allow you to understand how to wear a Harbinger lifting belt correctly. Keep in mind that the nylon version also incorporates the additional 3-inch strap. The strap can be wrapped around your lower back and should provide some additional stability to engage the lower back muscles.
