Erg (Ergometer)
What is Erg (Ergometer)?
Ergometer literally means "work meter" — a device that measures physical work. In rowing, "erg" universally refers to an indoor rowing machine, most commonly the Concept2 RowErg (formerly Model D and Model E). The erg uses an air resistance flywheel and chain mechanism to simulate the feel of rowing on water. Unlike weight machines or treadmills, the erg provides a variable resistance that responds to the force you apply — row harder and the resistance increases naturally. The erg is the primary testing and training tool in rowing, used for everything from 2K tests to marathon rows. It provides objective, comparable data that allows rowers worldwide to benchmark their fitness.
