It is something that we know from using the SkiErg ourselves, but it is always nice to have it confirmed by someone as knowledgeable and influential as Dr Valery Kleshnev in his Rowing Biomechanics Newsletter.

Valery compares the biomechanics of the double poling cross country skiing action with the action on the SkiErg and compares the Force Curves, Velocity and Power of the action, as well as comparing the action to the rowing stroke as performed by the same athlete. His overall conclusion - a workout on the SkiErg (is) a great full body exercise.
