Weights are available in both hard and soft styles. Hard weights come in two basic shapes: block weights and bullet weights.

Block weights are flat in shape and have two slits for weaving the belt through the weight. These weights are available in sizes ranging from one to over ten pounds.

Bullet weights are cylindrical in shape, and have one slit. These weights are available in sizes ranging from one pound to five pounds.

Most hard weights sold today are coated with rubber. This prevents your skin from contacting the lead, which is a known carcinogen. Another benefit is that it prevents the weights from scratching surfaces such as pool bottoms.
