The exercise ball comprises a spherical hollow rubber bladder () in which compressed air is sealed, and a yarn-wound reinforcement layer () formed by evenly winding a filament yarn around the surface of the rubber bladder, wherein the exercise ball is characterized in that nylon filament yarn, obtained by hard twisting two 30-50 denier nylon filaments--in a single-direction twist is used as a winding yarn ().
