Rowing machines have designs that consist of an energy damper or braking mechanism connected to a chain and/or handle. A foot stretcher (where the rower places her feet) is attached to the same mounting as the energy damper. Most include a rail that either the seat or the mechanism slide upon. Different rowing machines have a variety of layouts and damping mechanisms, each of which have certain advantages and disadvantages. The workout value comes from the whole body nature of rowing. If you have the space to devote to an indoor rowing machine, make sure you first try the rowing machine at the store.
