Are rowing machines and sitting rowing machines aerobic?

Rowing machine belongs to aerobic equipment, and sitting rowing machine belongs to special strength training equipment. Can't replace each other. From the picture, we can only see that both instruments are single-arm back-pulling, but in fact, the rowing machine is more complicated. Its seat can move back and forth. When the arm is pulled backward, the leg pedal and the seat move backward. Just pull your arm back, kick your leg, and pull the handle back with the same force at your waist. This is a simulation of rowing. The sitting rowing machine has a fixed trunk, and the handle is pulled by the strength of the arm and back. Rowing machine belongs to whole body exercise, while rowing by boat belongs to isolated muscle exercise. The rowing machine can be used for more than ten minutes, while rowing in a sitting position for a few minutes will cause backache.
