Powerlifting focuses on three main lifts: squat, bench press, and deadlift. In this discipline, maximum stability and support are crucial. Therefore, powerlifters often opt for belts with maximum thickness and rigidity. Both lever belts and prong belts are popular choices among powerlifters due to their ability to provide excellent support and easy adjustability. Additionally, belts with a width of 4 inches or 6 inches are commonly preferred to maximize core engagement during heavy lifts.

Bodybuilding emphasizes muscle development, symmetry, and aesthetics. While a weightlifting belt may not be as essential for bodybuilding as it is for powerlifting, it can still offer benefits during certain exercises, such as heavy squats or overhead presses. For bodybuilders, a belt with a moderate thickness, typically around 10mm, is often suitable. Leather belts are commonly preferred in bodybuilding due to their durability and ability to conform to the lifter's body over time.

CrossFit combines elements of various athletic disciplines, incorporating strength training, cardio, and functional movements. CrossFit workouts are often high-intensity and involve a wide range of exercises, making versatility and mobility important factors when selecting a weightlifting belt. In CrossFit, a belt with moderate thickness, such as a 10mm lever belt or a 7mm nylon belt, is often favored. These belts provide a balance between support and flexibility, allowing athletes to transition between different movements comfortably.

Olympic lifting includes the snatch and the clean and jerk, which require explosive power and precise technique. In this discipline, a weightlifting belt is primarily used to provide intra-abdominal pressure and support during heavy lifts. Olympic lifters often prefer belts with a moderate thickness, typically around 10mm, to strike a balance between support and flexibility. Lever belts or prong belts are commonly chosen due to their secure fit and quick adjustability, enabling lifters to focus on their technique without distractions.

Strongman competitions involve a wide range of events that test overall strength and endurance, such as lifting heavy objects, carrying loads, and pushing or pulling weighted implements. In strongman, belts with maximum thickness, typically 13mm, are commonly favored to provide maximum stability and support during extremely heavy and dynamic lifts. Lever belts or prong belts are often preferred for their ability to secure tightly around the waist and offer reliable support under intense conditions.
