This Erg Uses a Flywheel to Create Resistance

The indoor rowing machine or ergometer (aka erg) is used by rowers to simulate rowing on land, and to test their strength. The earliest machines were created sometime in the mid-1800’s. One design is the water-rower, which used water to create resistance. The most popular design today uses a flywheel to create resistance.
