Iron Woody "Fat Bars" are a great way to progressively develop your hand and forearm strength. If you have never tried them before, you won't believe how much harder it is to lift the same weight you have been lifting using thicker handle bars. Just ask someone who already uses them.
As usual, Iron Woody offers these dumbbells because everyone else charges too much for them. (We don't like getting hosed either.) Each set includes the clips. Check around and you will see they are a great deal.
