HOW TO DO ROTATION DRILL REALLY WELL
Small kicks are preferred over large kicks. The kick starts high in your body, not at your knees. Kick with the front and soles of your feet. Breathe with body rotation and then quickly reset your head to a neutral position, looking straight down. Keep your arms tight to your side.
Your legs will tend to curve behind you. Don't, stay straight in the water. A straight, slightly downhill body line makes this drill much easier. Move your balance point forward. Lean on your shoulder.
Here, Natalie Coughlin does the drill.
