Good.Hmmm... I suppose I curve my right arm first to defend myself from the attacks with my sword. The sword is in front of me and the tip is a little above my head level. Then I stretch my right leg and get up. I only raise my head and square my shoulders when my leg is almost fully stretched and I make a step backwards with my right. When I take the step backwards I start to lower my sword too to clear my sight and get a basic battle stance.
It's important to know why you don't go past your ankle: keeping your knee level with or behind your ankle allows you to use your ankle as a pivoting point. You can simply push backwards and downwards, deflecting through your ankle, and straighten back out, and rather quickly, compared to having to completely stand up by moving forward. When your knee goes past your ankle, you can't do this anymore, as the force is "aimed" at your ankle right. The reason? You're using your knee and ankle as a hydraulic press, to make a comparison. It just doesn't work with your knee past your ankle.
Now, if you're ready, we'll move on to Side-stepping, the first part in movement.
