Utthita Trikonasana a simple pose.
Sometimes my teacher asks me if the session was too hard or too easy. I reply as always - “It is never too easy.” You can think alignment, you can think breathing, you can think pranayama, pratyahara and if it is not enough try to put your ego aside for a milisecond before the chita vritis again.
Instructional designer works hard to identify an exercise or a situation, that will enable a learner to practice her core skills and reveal attitudes.
Utthita Trikonasan is doing it for years.
