Abstract A dumbbell provided with a weight at both end portions thereof. The weight is detachable from the dumbbell so as to make it adjustable in weight in accordance to the weight dealing capacity of a trainee. This dumbbell is also equipped with a grip promoting member at the grasping portion thereof also detachably therefrom, thus this invention is meaningful from the view point of economy and efficiency in training. The dumbbell has a handle and a threaded bar at each end thereof to receive threaded weights. Each unit of weights at each end of the bar is spherically shaped. Each unit of weight is composed of a plurality of parallel sections passing through the sphere. The axis of each sphere coincides with the longitudinal axis of the handle. The weights of each unit are in abutting relationship. The grip includes a spring and is mounted in a cantilevered manner to the handle. One end of the spring is detachably anchored in a reduced section of the handle at a position toward one end of the handle. The grip has a finger receiving portion.
A combination dumbbell and grip exerciser for performing lifting and gripping exercises simultaneously, comprising: (a) an elongated handle with a threaded bar at each end having a reduced cross-sectional area in the form of a notch toward one end thereof; (b) globular weight means detachably mounted on the bar at each end of the handle for providing resistance to lifting, each of said globular weight means comprising a plurality of units engaging each other in abutting parallel planes, said units when taken together form a sphere, the axis of said sphere coinciding with the longitudinal axis of the handle, each of the units provided with a threaded aperture for securing the units to said threaded bar, the outermost unit to be secured to the threaded bar without the threaded bar penetrating therethrough; (c) a grip force developer mounted in a cantilevered manner within said reduced cross-sectional area of the handle, said developer comprising a detachable plate spring having a finger receiving portion; (d) a holding member engaging an end portion of said detachable plate spring within the reduced cross-sectional area, such that the detachable plate spring is secured between the reduced cross-sectional area of the handle and the holding member.--
