A device for enabling a workout while providing balance training and methods for using the device. A specific embodiment of the device is in the form of a circular inflated body formed of polyvinylchloride plastic having a needle valve for inflating the body with air, a curved vertical surface, opposing generally horizontal surfaces, an ellipsoidal cross-section, and a diameter of between 12 inches and 18 inches. A flat circular depression centrally located on one of the horizontal surfaces has a diameter between 8 inches and 10 inches with a ratio of the diameter of the body of the device to the flat depression of from 1.2 to 2.25., the flat depression having a depth of 1 1/16 inches to 2 inches. Nubs are distributed over a horizontal surface opposite the flat depression. A method is provided for using the device to work out while providing balance training. A pair of the devices is used to support the arms or legs of a user while the user is performing an exercise. In one method, the devices support the flat surfaces of push-up handles to facilitate push-ups while providing balance training. In another method, the device supports the feet of a user to provide balance training while he or she uses weights.
