A gripping power training device includes a first holding component, a second holding component and at least two washers, in which a holding part the surface of which is undulated is installed on the top of the first holding component, and two pushing sticks are installed on two sides of the holding part respectively. An annular groove is formed on the end of each pushing stick for being engaged with the washer. The other holding part the shape of which is the same with that of the first holding component is installed on the top of the second holding component the appearance of which is similar to the first holding component, two cylindrical tanks the inner diameters of which are slightly larger than the diameters of the pushing sticks are installed on the bottom of the holding part for being inserted by the pushing stick of the first holding component and forming a sealed state between them. Then, the air compressed resistance is formed in the cylindrical tank when the first and the second holding components are pushed towards each other, the released elasticity is formed by the compressed air in the cylindrical tank when the first and second holding components are released, thus a gripping power training device is constructed.
