I watched my Olympic biathlon brethren go around turns. Some cranked the inside ski around before accelerating into the straightaway. Others put weight on the outside ski and pushed off into the turn, almost like alpine skiing. What is the best form?
Sorry to say but this all depends on every turn, the snow surface and your capabilities. As with all skiing you want to maintain momentum and minimize effort. You want to avoid hockey stop turns that scrub speed. Generally, the fewer steps you make the better. On real sharp turns you can pull your inside ski back and then push it into the turn and then follow that by skating off the outside ski.
Best way to learn is to follow a great skier and copy what they do, or follow a not so good skier and try different techniques and see if you are gaining or losing distance on them. sorry that I could not be more exact via email.
