What is Iyengar Yoga?

The Oxford Dictionary defines Iyengar Yoga as: "a type of ashtanga (hatha) yoga focusing on the correct alignment of the body, making use of straps, wooden blocks and other objects as aids to achieving the correct postures."
Iyengar yoga is named after BKS Iyengar (1918 -2014), who devised this method through direct experience and personal practice.
BKS Iyengar pioneered the use of props in yoga practice and developed therapeutic applications of yoga for those with illness and injuries.

What is a Certified Iyengar Yoga Teacher?

Look for the Mark

Iyengar Yoga is taught world-wide. To ensure that teachers protect and maintain the method developed by BKS Iyengar and his family, a standardized assessment system was developed.
In the U.S., the Iyengar Yoga National Association of the US (IYNAUS) is responsible for the assessment process.
Teachers undergo a rigorous assessment of standards in 3 categories: practice of asanas and pranayamas, a written exam, and demonstrate teaching skills.
Certified teachers must continue their yoga education to maintain their certification.
Only certified teachers can use the Iyengar name to describe their classes and use the trademark.
