An exercise device used to provide resistance to the contraction of a muscle during weight lifting. The exercise device consists of a handle with two weighted members connected on opposing ends of the handle. The weighted members are connected through a press fit manufacturing technique. Each opposing end of the handle has at least one channel about the periphery of the handle ends that is used to collect metal shavings generated during the press fit manufacturing process. By collecting the metal shavings, a connection that not only has a tight tolerance, but also has few imperfections at the interface between the flushed surfaces is created.
