Iyengar Yoga is a technical style of classical yoga. The classes focus on correct alignment, (inner) strength and deep concentration. The postures are studied with much detail and more time is spent in each pose.
Several props are used in Iyengar yoga, these include blocks, belts, ropes and chairs. These props can support less experienced students to fully experience the yoga poses and are also useful for the more advanced students to study the yoga poses (asanas) in detail.
Iyengar classes help to develop flexibility, strength, focus and relaxation.
