Urban Rebounder 1 Lb. Sand Weights

I like that there easier to handle than iron dumbbells and if you drop it on your foot, well it will not hurt it. The con is they are very expensive, $33.00 dollars, they contain iron sand but they are soft to touch. Anyway if your looking for something to use doing aerobics, give these a try. They come in 1lb, 2lb and 3lb.
