Because ice is so hard and slippery, you need to push really hard on a razor-sharp metal edge to get any traction. On ice, if you are not on an edge, your blades tell you immediately by making a loud scraping sound. When you eventually learn to find your edge, skating becomes a beautifully silent activity. This sense of security, in turn, lets you relax and concentrate even more on your technique. In order to move from your inside edge to your outside edge, you must learn to controll your weight transfer from one stroke to the next.
Weight transfer is a skill that is common to all forms of speedskating.
Because of the two-edged nature of ice speedskating, weight transfer is learned with greater subtlty on ice. Weight transfer is an especially important element in complex movements such as the double-push. In other words, ice can do nothing but improve your inline technique. Your first move should be to try ice speedskating out locally. This is easily accomplished.
