The Rock Step consists of two weight changes in opposite directions to 2 beats of music. This dance move is typically called, “Rock Recover” and is useful for changing directions. Did you know that no matter which direction you rock (cross, side, back, front) your weight remains on the forward part of the foot-never the flat foot or heel.
Rock Steps forward and backward are the same as Break Step in Latin dances. The feet should remain beneath the body in 3rd or 5th position using a cuban motion. The magic of cuban motion is waiting until the last moment to shift your weight and straightening the knee as the weight is shifted.
 If you lower your heel performing a back rock, you should still keep your weight on the forward part of your foot. For your safety, do not lean back when dancing a back rock, keep an upright body posture with weight distributed between your feet. You may need to watch yourself do a back rock in the mirror to see if you are in the habit of leaning back. If you are leaning back, take the time to correct it to prevent future injury.
Side rocks are performed in 2nd position and the feet are kept close to the body so as not to throw the dancer off balance. The weight remains on the front part of the foot even when stepping to the side. Dancers will talk about rolling around the ball of the foot on a side rock. Try it out!

​A Paddle Turn is usually a 360 degree turn utilizing 7 weight changes on the ball of the foot while leaning in the direction of the turn. 
1 - Left foot steps 1/4L
& - Right foot side R
2 - L 1/4L
& - R side R 
3 - L 1/4L
& - R side R 
4 - L 1/4L
The Push Turn is a variation of the Paddle Turn with one definite weight change and six partial weight changes. Following the above pattern you step your left foot 1/4L on count 1 and the ball of that foot remains on the dance floor and the heel is elevated to allow the turn as you push yourself around on the & counts.
Do you differentiate between a Push Turn and a Paddle Turn in your danicng? I like a Push Turn, but if the floor is sticky; or, I'm dancing on a rough surface, I  substitute a Paddle Turn to protect my joints.
