In most of the skills involved in normal skating where you're on one skate, you need to align your body so that your nose, knee and toe of one skate are in a straight line. The best way to show this is to do the following on grass:
- Stand in a wide ready position.
- Look straight down, you should see grass and the insides of your skates (if you don't make the stance slightly wider!)
- Still looking straight down, move your body towards one foot (I'm going to choose my left one).
- Keep moving your weight until, from your perspective, your knee covers the toes of the skate.
You should end up in a stance that approximates a right-angle triangle: your left leg is the vertical side of the triangle, your right leg is the hypotenuese, and the space between your feet is the base.
