The Marcy Pro Water Resistance Rower with Pulse Sensor NS-6023RW delivers the intensity of a lake rowing workout to your home gym. By using water as a form of resistance, the NS-6023RW replicates the quite, smooth and natural feeling of rowing on water. Water resistance rowers are preferred by many because the resistance produced by the water naturally increases the faster / harder you row. You can't make progress if you are not tracking progress. The Marcy rowing machine has a high-density foam seat that is ergonomically molded to provide comfort during long workouts. The firm handle provides excellent grip to ensure it does not slip during use. And, the large pedals with loops ensure your feet do not slip. In addition, the NS-6023RW helps save space by storing vertically. Once you know where you want to place the rower, you can lift it vertically as shown in the manual to save space while storing the unit.
