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