Sunpentown International introduces the revolutionary exercise equipment - the Giddyup!� Core Exerciser. This equipment simulates the actions of horseback riding with its single motions: a horizontal 8 motion. As the equipment goes through its motions, the rider is constantly thrown off-balance. This requires the rider�s muscles to involuntarily contract and relax in an attempt to re-balance and stay upright. This reflex action, known as counter-balance exercise, reaches the deep postural muscles of the pelvis and muscles of the thighs, quadriceps, hamstrings and glutei. The most appealing aspect of this Counter-Balance motion is that the user is exercising without really doing anything, as there is no exertion from the user.
