Iyengar Yoga, named after and created by B. K. S. Iyengar, is a form of Hatha Yoga that has an attention on detail alignment and precision in the performance of posture (asana) and breath control (pranayama). The development of strength, mobility and stability is gained through the postures. B.K.S. Iyengar has systematized over 200 classical yoga poses and 14 different types of Pranayama, all designed to guide students toward more advanced understanding and inner intelligence as they gain flexibility, strength and deeper meditative practices.
Iyengar Yoga often makes use of props, such as belts, blocks, and blankets, as aids in performing asanas. The props enable students to perform the asanas correctly, minimising the risk of injury or strain, and making the postures accessible to both young and old.
