The Cybex VR1 dual abdominal & back extension, similarly to other machines in the Cybex Duals line, utilises multi-function mechanisms to get two exercises in one machine which is an excellent solution for facilities with limited space & budget. The special design of the VR1 dual machine enables focusing on the abdominal muscles without involving hip flexors, arms or shoulders. The machine also offers back extension type of exercises which are often prescribed to minimise chronic back pain. Full range of motion on the device is ensured by the lumbar curved section of the hip pad with six starting positions. The machine comes with a standard weight stack of 86kg (190lbs).
