ABSTRACT:
Exercise dumbbells are made with weights at opposite ends of a handle member. Exercise kettlebells are made with weights beneath a handle member. The weights may be selectively connected to the handle members using knobs and springs, for example, to alternatively hold the selector members in weight engaging positions and weight releasing positions. The dumbbells and the kettlebells may be made using some of the same components.
