发明名称 Balanced stackable dumbbell system
摘要 A dumbbell system ( 10 ) is provided including a base weight member ( 12 ) having a ring-shaped body ( 14 ) and a handle ( 18 ) extending across an opening ( 16 ) in the ring-shaped body ( 14 ). A plurality of weight rings ( 20, 22, 24 ) are adapted to be removably mounted to the base weight member ( 12 ) in order to provide a compact dumbbell system which has the capability of providing several weight increments in a compact assembly. The dumbbell system ( 10 ) is ideal for use in areas where space is limited. The dumbbell ( 10 ) also provides for a unique balanced mass arrangement which alleviates undesired stresses on a user's wrist.
