Ashtanga Yoga developed by K Pattabhi Jois is a dynamic, physically demanding practice which synchronizes breath with a progressive series of movements to produce an internal heat designed to purify the body. Ashtanga is great for building core strength and helps to tone the body. Prepare to sweat as you briskly move through a set sequence, detoxifying muscles and organs. The result is improved circulation, a strong body and a calm mind.
