I met a Canadian from Squamish, British Columbia on the 2nd day of Haute Route. He used to telemark and now he parallels. Well, I don't want to just rely on parallel turns. It is too much fun to miss.
Yes, if you parallel ski, you are missing something; telemark turns. I do parallel turns but the most enjoyable ski experience is telemark turns. It makes me feel I am in a luge going fast and stable in big forever arcs. When doing a good carve, centrical force makes the telemark stance so natural.
This is the site for stretches and conditioning and exercises that will help me enjoy "telemark ski forever".
