The present device relates to a gym ball capable of preventing the slipping or falling of users who have difficulty in keeping their balance, such as, children and the elderly, when they do exercise, and capable of allowing the users to freely do exercise to build up the health. To this end, the 'spherical shape' of the gym ball is changed into a 'cylindrical shape' to prevent the gym ball from slipping aside. Edge frames are formed on both sides of the gym ball, and the diameter of the edge frame is larger than the diameter of a main body (100) of the gym ball. Further, rubber protrusions (200) are formed on a lateral surface of the cylindrical gym ball to prevent the users from slipping frontward or backward during the using of the gym ball. Further, the gym ball provides an acupressure effect. |
