A gym belt, also known as a weightlifting belt, is an essential accessory for fitness enthusiasts who engage in heavy lifting or strength training. Designed to provide extra support to the lower back and core, it helps maintain proper posture and stability during intense exercises like squats, deadlifts, and overhead presses. By reducing stress on the spine and improving intra-abdominal pressure, a gym belt not only enhances performance but also minimizes the risk of injury.
