An inertial exercise device includes an internal hollow casing containing one or more spherical shaped weights for rolling and/or sliding movement within the hollow casing. The weights have an initial force imparted to them by a user of the exercise device. Once set in motion, the mass of the weights provide an inertia to the exercise by requiring the user to maintain the movement or work against the movement of the weights. Different types of motion can be imparted to the weights so as to provide exercise of varying difficulty and to provide exercise to different muscle groups.
