Cybex VR3 Abdominal, the CYBEX VR3 resistance strength line exercises the theory that form and performance belong together. VR3 is a collection of machines that combine striking appearance, excellent performance, genuine comfort and accessibility - without sacrificing the goal of functionality. If you want form and performance, the VR3 line delivers both. Because the design has taken hip flexors, arms, and shoulders out of the movement, the resulting exercise is completely focused on the abdominal muscles.
