BP Gradieter / Indoor sports equipment

BF Gradienter is a kind of fitness ancillary product. When bodybuilders do freestyle bench press, as their power generation towards barbell is uneven in consequence of dominant hand, as well as the weak self-awareness, their breast shape becomes asymmetric gradually. The supporting role of this product lies in that when the barbell is tilted, the water level meter will be off-center position, which suggests the bodybuilders to adjust their actions.
