Weight and holding training device

A weight and holding training device comprises:

• two sets of end casings, each set of the end casings being composed of a pair of half casings and forming a substantially hollow structure by assembling said half casings' hollow sides together, said two sets of end casings being facing each other, each set of the end casings having two openings on the facing side of said two sets of end casings, said two openings being separated by a predetermined distance;
• a balance weight element being substantially bacillary with predetermined weight, both ends of said balance weight element protruding into the corresponding openings of said two sets of end casings so as to be fixed;
• an elastic element being a spiral spring with predetermined resilience, both ends of said elastic element protruding into the other corresponding openings of said two sets of end casings so as to be fixed, said elastic element being flexible;
• aforesaid elastic element and balance weight element being assembled with said two sets of end casings and forming a close-loop frame, a distance being set between said elastic element and said balance weight element, the distance allowing said elastic element to deform while a user is holding said two elements, said deformation further creating a resisting force against said user's hand or fingers simultaneously so that both functions of weight training and holding training can be achieved.
