Fixing the Body Rotation
the reason why most people’s legs twist and cross is because their legs are trailing the body rotation, instead of moving with the hips and body. The key to fixing it is making sure to get good range of motion with the entire leg, not just from the knees down. Make sure to control the kick all the way from the hips/upper thigh. That way when the hips rotate, so will both legs at the same time. This is definitely not mentally or physically easy if you’re not used to it, so be patient. If your legs are only crossing when you breathe, it could mean that you’re over-rotating to take the breath, and it’s simply impossible to sustain an even kick when your hips are rotated too much. If this is the case, try not to twist your body as much to take the breath.
