Picture the golf swing as a symmetrically balanced motion.

• For example, in the backswing, that is anything that happens right of the ball (for a right-handed player), the right hip and shoulder turn to the right, the right elbow folds, and the left knee moves slightly to the right. In the forward swing, the left hip and shoulder turn to the left, the left elbow folds, and the right knee moves to the left.
  .
  The only difference is the range of motion may vary from backswing to forward swing, due to momentum. The backswing is started from static, and the forward motion has force through motion.

Thinking of the golf swing as a symmetrical motion; this will aid your consistency.
