Hard weights are designed for use with a 2-inch belt. The belt is woven through the weight, and weight keepers secure their position. The figure to the left illustrates the weight keeper configuration for both block and bullet weights. As you can see, with bullet weights the keepers are placed at each end of a row of weights, while with block weights, the keeper is placed between the two slits.

The weights should be positioned on the belt so that when worn, the weights are positioned over the hips. Also, make sure an equal amount of weight is placed on each side of the belt. This helps prevent your body from rolling to one side while diving.
