What is the primary function of a weightlifting belt?

The primary function of a weightlifting belt is to provide additional support to the lower back. When weightlifters perform heavy lifts, particularly in exercises such as squats and deadlifts, the belt helps to stabilize the core and maintain intra-abdominal pressure. This pressure acts as a natural brace for the spine, which can potentially reduce the risk of injury and enable the lifter to lift heavier weights more safely.

The support provided by the belt encourages proper posture and alignment during the lift, allowing the lifter to focus on technique without compromising their lower back health. While other options may relate to aspects of weightlifting, they do not capture the main purpose of the lifting belt as effectively. For example, while a belt might indirectly contribute to performance enhancement, its main role is specifically related to back support, rather than enhancing grip strength or promoting breathing techniques.
