The Iyengar system of yoga emphasises precise and careful body alignment, muscular balance and maximum spinal extension. The postures, known as asanas, have a variety of different effects, stimulating, calming, energising, building stamina and vitality, promoting sleep and soothing internally. Many physical ailments, including chronic disorders, can be improved with steady practice. It helps release tensions, improves posture and gradually retrains the body to become stronger, more supple and healthy. This course is suitable for those who have already completed two to three terms at Bishopsgate Institute, or have substantial previous experience, and wish to deepen their understanding of the practices. For Level 2 and beyond you should be steady in standing poses and familiar with inversions.
