Do you work in the wrapping exercises with tension as part of (a variation of) the 13 basic exercises, or do you do these as completely separate exercises?

The wrapping exercises with tension are pretty new to me, so I am not sure I am doing them correctly yet. Maintaining two-direction energy seems to be an important aspect of the exercises.

I try to be pretty strict on keeping the 15 basic exercises "pure", and any alterations I want to do, or additions like the tension exercises, I do in addition to the basics.

Agree about two direction energy. It seems extremely important. When I'm first getting started I'll often do the static positions to feel as much two direction as I can.
