The SkiErg is a great tool for working on ski technique. I use it to practice short, medium and long styles of poling. I also use it to develop a strong, activated core position that I can maintain while skiing. Once I figure out how to make a new element of ski technique "click" by using the SkiErg, it becomes easy to apply the change on snow. I have become a more efficient skier over the last few years thanks to the SkiErg.
