An indoor rower, or rowing machine, is a machine used to simulate the action of
watercraft rowing for the purpose of exercise or training for
rowing. Indoor Rowing has become established as a sport in its own right. The term also refers to a participant in this sport.An indoor rower is also known as an ergometer (colloquially erg or ergo), an ergometer being a device which measures the amount of
work performed. The indoor rower is calibrated to measure the amount of energy the rower is generating. Ergometer comes from the
Greek word's ergon, meaning work, and metron, meaning measure. "Ergometer", therefore, literally means "work measurer".
