The secret to flowing and powerful forward crossovers is knee bend. More knee than you ever thought possible. And then some. It will feel ridiculous to start with and you'll be certain it looks even more ridiculous than it feels but, trust me on this, it isn't and it doesn't. And once you get that knee bend, you can start to actually have two pushes in each crossover, one from the outside, crossing foot and one underneath from the inside. Keep your bottom tucked under and your head up, with your outside arm forward and your shoulders facing towards the inside of the circle.
