How “tough” is Iyengar yoga?
Iyengar Yoga is not “tough” but it is demanding. Correct yoga requires being totally involved physically, mentally and emotionally in one’s practice. As Yoga is concerned with the growth and development of the individual, this means extending one’s current comfortable limits. Thus yoga requires that one work beyond what is necessarily easy but obviously not to the point of distress. Yoga should be a constant challenge but never an assault, and the teacher’s task to continuously raise the standard for the student so that there is always room for progress.
