ABSTRACT:
An exercising device includes a ball, and a rod extended through the ball. Thus, the ball has a periphery formed with two through holes each having a peripheral wall formed with a pressing lip which presses the rod closely after the ball is inflated to form a sealing effect to seal the chamber of the ball to maintain the air in the chamber of the ball, so that the ball is sealed on the rod exactly without incurring air leakage. In addition, the manufacturer only needs to form two through holes in the periphery of the ball without having to form a hollow channel which is extended through the whole diameter of the ball, thereby facilitating fabrication of the ball, and thereby decreasing costs of fabrication.
