A waist trimmer is a fitness accessory designed to be worn around the waist during workouts. It typically consists of a wide belt made of neoprene or similar materials that can trap heat and increase sweating around the midsection. The main idea behind waist trimmers is to increase core temperature, which can potentially help burn more calories and promote weight loss around the waist area. Some users also find that waist trimmers provide support to the lower back and abdomen during exercise.
