Placed Footwork
Practice footwork that looks placed, not forced, in this house drill. Keep your knees soft and the bounce going, since jacking is the heart of house.
Your upper body does the lifting. When a heel pushes forward, the body goes forward with it. When the toe goes back, the body goes back too. Used this way, your abs help the feet move faster, instead of the legs controlling everything.
Heel-toe, then a cross, then legs going out, in and out with a bounce between each one. Precise timing matters more than speed.
