Erging is a term used to describe the act of using an ergometer, or "erg" for short, which is a machine that simulates rowing without an actual boat. It is a common training tool for rowers, especially during the winter months when being on the water is not an option. The erg machine is designed to mimic the rowing motion that a person creates when in a watercraft but operates on land. The machine measures the amount of work performed and provides feedback on metrics such as strokes per minute, split time, and distance. Erging involves a sequence of drive and recovery, where the user drives with the legs, rocks back with the back, and pulls with the arms. While erging can be a great way to promote overall body strength and aerobic fitness, it is often viewed as a challenging and even torturous experience by rowers due to the intense focus required on metrics and the lack of the natural environment of being on the water.
