"Anonymous. What are you on about. You are in bad shape if you cannot step straight ahead and apply CBM or CBMP."
First, straight forward relative to what?
As I explained, you can step straight forward relative to your foot. What you cannot do is step straight forward relative to your body - it does not work when dancing with a partner.
Also, CBMP is by definition a step taken diagonally across the alignment of the foot, and so it is not forward either. In dance terminology, "forward" is a direction (relative to the feet) and "forward in CBMP" is a DIFFERENT direction (a diagonal one), also relative to the feet.
"Don't forget to turn at the end of the step and not the beginning."
That depends on the direction and the body part.
For natural turns, the body rotates early in the step. For reverse turns, the body rotates late in the step and the hips rotate before the shoulders.
For forward CBM, the feet turn after they are placed. For backwards CBM, the foot toes in some on the first step, and the following step will be pointed in the new alignment before it is weighted.
"Sigh!! I don't know what the world is coming to."
Well, when you get such basic elements of technique wrong, who do you have to blame but yourself?
