An abdominal belt, sometimes referred to as a waist trainer or corset, is a garment made from elastic materials that compress the abdominal area. It is commonly used during physical activities, including exercise routines like weightlifting, running, and even everyday movements, to support posture and improve overall performance. The primary goal of these belts is to promote sweating in the waist area, which some users believe can lead to a reduction in waist size and body fat over time.

Ribbed belts are characterized by their ribbed design, featuring multiple longitudinal grooves running parallel along the length of the belt. This unique structure provides several benefits over traditional flat belts. Firstly, the ribs increase the belt's surface area, enhancing its grip on the pulleys and minimizing slippage. This design also allows for better distribution of load, which reduces wear and tear, ultimately extending the belt's lifespan.
