The stance - Think of your knees as a peak of an 'A' . By inflexing your knees, you set your skates on their inside edges which translates into some major wheel-edge friction, keeping your speed low & overall control high. Remember; bent knees are the key to all forms of the swizzling technique!

To move forward, do the a-frame shuffle; keeping your knees inflexed (wheels on inside edges), push outward a few inches (stroke) with one skate, the other & after the outstroke, unweight your skate & slide it back to its original position (recovery). It is not necessary at the earlier stages to actually lift your wheels off the ground during recovery---unweight & slide.
