The thickness of the fitness belt determines the hardness. The higher the physical fitness level, the heavier the weight. It is suggested that the thicker the fitness belt, the better the protective effect. The thickness of the weightlifting belt is generally between 5 mm and 8 mm, and there are some cases with a thickness of10 mm.

At present, there are basically three kinds of fitness belts on the market: nylon, weightlifting and strength type. Weightlifting type is more suitable for our fitness, giving consideration to comfort and practicality.
