Doing yoga this many days in a row and working hard every day will create a positive spiral. I have thought about this a while as I have watched instructors and others who do daily practice, as they hardley ever stand out a posture.
Working hard -> gives more muscles and strength -> more energy to work with -> working harder ->
Every time I even think of not doing a posture I think of this and how it will stop the positive spiral and add to the negative one instead. When the spiral is above a certain level it needs a lot to break the spiral.
It’s the same with the intensity in the postures. Working intense today will give tomorrows posture a easier start.
