ABSTRACT:
An exercising device is provided with hand grips, being positioned between a pair of torsion springs and carried by a dumbbell are eccentric to the weight of the dumbbell which allows gripping exercises to be performed independently of the dumbbell and which also allows gripping exercises to be performed simultaneous with raising and lowering of the drumbbell. This structure provides an "anti-throw out" guard when the user thereof is performing simultaneous gripping and lifting actions, such as is common in modern aerobic exercises. The device includes an elongated weight bar having reduced end portions which carry weight members and a resilient torsion spring member. The resilient torsion spring member has first and second torsion springs which are positioned substantially parallel to each other for receiving the respective reduced end portions of the weight bar therethrough. Each torsion spring has a pair of spring legs extending therefrom, and a rod is positioned between, and integrally formed with, a respective spring leg in each pair of torsion springs. In a preferred embodiment, a pair of protective covers are annularly disposed on a respective rod member.
