The GR rower is designed for fitness. Utilising a 1.23m rail and 6.5kg flywheel, the ZR Rower provides a smooth action for your workout. With 12 pre-set programmes, heart rate control, race mode and a manual programme, the opportunities for versatile cardio exercise are almost endless. The 16 resistance levels provide you with the platform to adjust your workout easily through the LCD monitor, coupled with a wireless heart monitor to keep track of your heart rate. The rower works on an electronic resistance system.
